The spinnaker chute is of composite manufacture. The bow moulding is joined to a sail- cloth sock inside the hull. The sock is tensioned and has a drain through the stern. The design of the splash boards around the chute opening was found necessary in choppy conditions. A new RA being built has a solid chute right through the total length! This may have advantages.

FLYING THE SPINNAKER The Halyard winch is geared to hoist the kite in ten seconds. This winch can be switched to hoist before reaching the windward mark because of the ten second delay. Care is needed to stop hoisting once the spinnaker is near the topmost position. Brace winches can now be used to position the spinnaker for best results. With careful adjustments it is possible to carry the spinnaker with the wind slightly forward of the mast. Dropping the spinnaker 1 accomplished by reversing the Halyard winch so that the down- haul retracts the spinnaker centre into the chute, care is needed to release the brace winches at the appropriate time as well as to stop the Halyard winch on full retraction so as not to overload the Halyard system. EXPERIENCE SO FAR As mentioned before the system has been fitted to our RM and RA, both of which I used in the last Australian Championships in Hobart. The RM never looked like going and ended up well down the fleet. Subsequent evaluation confirmed problems of boat balance, fore and aft trim and too much lead in the keel. A skipper must be prepared to change battery packs during a series of races to maintain voltage. It is my opinion that an RM using a spinnaker needs to be in the 161b displacement range or too much lead is lost from the bulb and the model becomes tender when the wind blows. A spinnaker system is more feasible on an RM (or even a R10R) where the model weighs more. With the RA the loss of length in the spinnaker pole due to the method used does necessi- tate making allowances when reaching due to its insufficient length near the forestay. Whilst my KNOW-ALL was fitted with a spinnaker in Hobart the system was unused as up my spare battery pack and could not afford to lose voltage unnecessarily. I blew The model proved to be competitive without anyway. Subsequent development on my own part has been to design two new RM’s not using kites and find the best one for future development with a kite. The new KNOW-ALL 2 is slightly heavier to take advantage of improved performance in heavier winds. development on the spinnaker system in The only new the making of new pole-pivots which will give a cleaner deck appearance.

Perhaps much reduced from last year’s 22 boats to only 12. a factor common to many races this year, the small band of enthus- iasts entered were almost out-numbered by the members of Birmingham M.Y.C. who mustered to assist the running of this first national at the Witton Lake since a rather unhappy RM event in 1975. Wind conditions on Saturday were light but definite, and a long course gave 15-20 minute races for 8 boats, meaning that no-one had long off the water. Indeed one or two skippers were amazed to find they were in 4 successive races, a total time of around 14hours on the wter without a break. Sunday morning brought beautiful sunshine and no wind! Disaster! Worse still I listened to about 12 different versions of the ideal course and ended up with one that pleased no-one! Fortunately the wind veered to a breath coming from basically one direction and we completed 2 schedules. Each race in this latter period was surprising how many boats were able to stay with the taking 25-30 minutes but it was leader unless they suffered a real “hole”. The design situation is rather like the RM scene of 4/5 years ago, in that converted old heavyweights with lots of sail are normal, ideal for them. and of course the conditions this year were John Cleave’s boat was a Ken Jones built Lewis design to their usual standard and when he threatened to sell it at the pondside a queue formed!

The 0.0.D. gave his briefing at 10.00am on Saturday and sailing started promptly at 10.30am. with light S.W. winds. A course was set giving the desired long beat to windward and leaving the mark to port. During the day the direction of start was changed several times to accommodate wind shifts. On the Saturday it was planned to sail two standard 17 entry 8 boat schedules. Skippers agreed to race as late as necessary to get through as many of the 34 races as possible. Racing had to be abandoned, with four races left, at about 6.00pm as the wind completely expired. Racing started at 9.45am on the Sunday with moderate winds but still not too strong for “Nookie Bear 80″ the over night leader. After sailing the four races to complete the schedule three six race fleets were sailed finishing at 3.45pm in time to add the scores for presentation of the prizes by the Mayor of Charnwood Borough Council at 4.30pm.

The hole in the inset in the tube (A) is suggested as No.70 drill; making pins are between .023-.025 ins. most dress- and a No.70 drill gives sufficient clearance without being sloppy. (b,c) Again, the average pin appears to be about one inch under the head. In order to give enough protrusion with the pin inserted to see where it’s going, (c) should be about -875 ins.

Insert the pin Assuming the pin length Dimension (b) controls the maximum length of I suggest about .625in. This latter dimension (b) should be repeated where indicated on drawing. MATERIALS The prototype was made from the scrap box and as the sketch only indicates a general principle, it is suggested that those made by the readers are also likely to be put to- gether using odds and ends. It may be important to point out that if pins are left to locate timbers during a glueing process, some glues are corrosive. a mild steel punch and is not subsequently cleaned out, If glue feeds back to punch and tube may become perman- ently rust-welded. Brass, stainless or other material generally non-corrosive are preferred. A warning with regard to the knob; if birch ply is being pinned (the punch will reasonably easily push a pin through .375in birch faced ply) some effort is needed and if the knob breaks the thinnest round metal bar used will penetrate the hand as easily as the pin goes through the ply – perhaps more easily! The tube (E) is the same tube used for (A). It is in fact drawn to a dimension that will give maximum penetration of which the tool is capable. Spare tubes (£) that reduce the dimension (b2) can be used to reduce the penetration. Several can be made and used as needed; they will of course be longer. If the tool is used to pin balsa, it is suggested that the weakest possible spring (F) is used and that the tool is made with a large diameter at it’s “operating” end. This will minimise “bruising” of the timber. Further, it is essential to remember that the tube is only the carrier for the pin and needs only sufficient spring force to return it to the “static” position, all the “push” should go through the plunger. The slot and pin in (A) and (B) are only needed to ensure the plunger stays within the tube. Any suitable method can be used to hold the nipple in (A), the pin in (A) and join the knob (B) to (C). As far as possible the tool is very simple; it is the principle and not the method of construction that is suggested and readers can adapt scrap material to produce a similar model which takes a lot of the fiddling out of planking a boat hull.

(Copied by permission from the Tasmanian R/C M.Y.A. Australia) The racing rules are primarily intended to prevent collisions in the close-quarters sailing situations encountered in racing. However, by placing one’s yacht correctly and anticipating one’s opponents’ intentions, it is possible to make use of the Rules’ inherent right-of-way “rights” in such a way as to hamper, hinder, frustrate, and infuriate the opposition. down, and it gets This enhances one’s own chances in two ways – it slows the other b—‘s ‘em edgy, so they don’t sail as well. Some typical ploys include: When a Port-tack start is favored, sail along the line during the last few seconds of the countdown on Starboard. This causes mild consternation among the fleet, which will typically be tightly bunched, on Port, and heading for you on a collision course. You have the choice here of – Bear away to avoid shouting PROTEST at the top of your voice, and thus penalize the entire fleet, or – Tack onto Port – this puts you over the line in front of the fleet! Again you must shout PROTEST and complain bitterly about people who don’t give right-of-way to boats on Starboard. Moan enough and you’ll be first round the windward mark before anyone realizes they’ve been foxed. If the OOD tries to recall you for starting early, demand a general recall on the grounds of “unduly prejudiced”. There are risks attached, naturally. If the fleet does avoid you, you finish up in dirty wind at the back of the fleet. If the fleet sails into you, you may get them disqualified, but your boat will be in a helluva mess after being sailed over by a dozen RA’s. Still, faint heart etc. When you’re well behind the leaders, position yourself (on Starboard, of course) as you approach the windward mark so that you can intercept a group of yachts who have rounded and are running towards you. They, being “windward” yachts, must keep clear. This is especially good fun in heavy weather, as the avoiding yachts may broach or gybe and, with luck, may be dismasted. For maximum effect, try to aim to cut across their bows with about two millimetres to spare – that really makes ‘em jump.” At the leeward mark, if you are on Starboard and boats are tacking back on Port you have rights, and should aim for them and claim your rights. As a running RA can be a fearsome sight, they will keep very clear indeed, and if you make some comment about “not handling so well downwind” they may even go ashore to avoid. If the awkward b—s are on Starboard as they tack away from the mark, it’s your duty to avoid, and you sail by the Rules, don’t you? So avoid by crossing his bow with half a millimetre to spare – it’s legal, if he didn’t touch you, you avoided him didn’t you? This is known as ‘giving way’ – if you do it right, and you’re moving fast, it’s the opposing skippers knees that will give way! In open water, when someone tries to overtake you to windward, luff PROTEST as he bounces off you. Point out that an overtaking yacht should beware of unintentional luffs caused by its own wind-shadow, it. Suggest that Bernoulli deflection is a common occurrence in a and he’ll accept his Being overtaken to established. up sharply and shout must keep clear, and but be technical about lee-bowed configuration penalty points without a murmur. leeward offers less scope – you need to keep clear once an overlap is If you can’t drop down in front of him so that he rams your transom before he overlaps, you can still drop down on him very gently until a bounce occurs, then whine loud and long about luffing rights and mast abeam, etc. Or, better, tack away just before the bump, shouting (guess what?) PROTEST, advise the world in general that the moron supposedly in charge of that thing has forced you to tack to avoid collision. long – if you can convince the OOD that he should be awarded two points, Moan loud and the sore throat is worth it. At a mark, the astute skipper must be first in the shooting stakes to claim (or, if he’s “outside”, refute) buoy room for an overlap. If you are within half a length of the yacht in front when approaching the buoy, shout OVERLAP, at the top of your voice, some apologetic remarks about having to observe these rules even Tf you are ‘outside’ yacht, abeam or slightly ahead. late and that you must Make overtaking yachts then make though they are irritating. shout NO OVERLAP unless the inside yacht is clearly comments to the effect must keep clear, 12 then that he established park him on the buoy. the overlap too These are only a few possibilities for winning friends and influencing people. Rules are full of situations which the crafty skipper can use to his advantage. The A VALUABLE PRIZE will be awarded to the reader submitting the tactic which, in the opinion of the Editor, is most likely to lead to personal abuse and violence whilst still being “within the Rules” to the extent that should a Protest result, the Protest Committee would probably accept tion if suitable, the manneuvre as “legal”. So, let’s have ideas, for publica- so that we can sharpen up our tactical sailing prior to the Nationals.

The first day saw very light winds giving slightly fickle conditions but just maintaining a strength to allow a starting round of 6 boat races to find a rough order of merit. The scores in this round were not carried forward to the fleet racing which followed. A glimpse at the results sheet will show that “A” fleet comprised a number of very well Starts were known names and in fact the sailing in this fleet was of a very high order. always in a close bunch and even at the end of a race lasting 15 minutes the entire fleet would finish within close range of each other. In other words, the one-design concept was producing boats capable of sailing on equal terms and sailing tactics were crucial. Unfortunately this applied to “B” fleet as well and there are some of us who managed to win their way back into “A” fleet after one round only to sink back into obscurity after a brief moment of tactical lunacy, or simply discovering that most of “A” fleet could get the same boat to point higher and faster than we could. Nevertheless, the entire entry enjoyed the sailing and the second day produced enough wind No-one did so in the end, and as a result to make people think of using second suit. those with less experience soon found that a long run down 200 yards of Fleetwood bordering on broaching at any moment was an exciting experience on it’s own, let alone in company with several other boats in close proximity. The sad fact is that the event failed to attract even a small percentage of the nearly 500 kits sold so far in the U.K., and even members of the class association who do not otherwise sail competitively. Was it the prospect of meeting the “superstars” that put them off, or the expense of Either way the class is not producing travel and living costs for a two day event. newcomers to model yachting and only spreading the existing people over yet another class. A move to a one-day event next year, hopefully in the Midlands, may be one solution.

SCOTLAND At the risk of offending Hughie Shields I include Scotland in this section as many are unaware that it has a separate Association which controls racing and registers boats. Recently met Chris Mackenzie, the R/C man from Inverlieth Edinburgh. A lake I have sailed on myself, whilst staying in Scotland, I was pleased to hear that the current strength includes 30 6 metre boats and a similar number of Mclass. Radio-control is just catching on and may give a new lease of life to many of these boats which have a long history in the club. Before moving to the present site near the centre of Edinburgh, the club sailed half way up ARTHUR’S SEAT, which in case you don’t know is a very large outcrop of granite commanding wonderful views of the surrounding city. The road which traverses the peak has two small lochs which always struck me as suitable for model yachts and it seems that back in 1891 they were used for the purpose. Wind conditions would have been rather different to the sheltered water now used which usually gives top-suit winds.

This A short Graham managed to keep in the top fleet but was disappointed to find that the final had been sailed before he even knew what it was! Winner was Harvey Hensen, winner for past two years in RM class and also 1980 and current RA Champion (two RAs only!), He used a Trapper II and a Trapper IV placed 3rd with Graham 4th! A week later, and not put off by the lack of regard for the rules in Denmark, Graham sailed in the Swedish RM Nationals in Stockholm. Again the race was organised in a fleet system with 23 entries taking part. Here the band of quality competition was somewhat broader and the local’s knowledge of the rules and tactics much higher. As a result the 7th place gained by Graham, now almost addicted to RM racing, was a little more pleasing. Winner was Bengt Bellander using a CF mast and sails with a very familiar label in the head patch on a 101b total displacement boat. Second was the previous year’s winner with another Swedish design and Nylet sails with Torvald Klem, Norway, 3rd, using a Challenger and Bantock sails. A second Norweigian entrant used a Trapper IV and told me that the four Trapper Vs sent out by Oliver Lee only a few weeks prior to the event were already sailing and very fast too! This whole event was efficiently organised by SMSF who are seeking recognition by IMYRU in place of the existing Swedish authority who held their own Championship the following week. U.S.A.

On Bank Holiday Monday we piled into the car and headed towards Southwold, our arrival timing nicely (another coincidence) with the 2.15 start.

The family spread their lengths on the grass around the lake. and if little else turned up to amuse us we could at about until the effects least It was a sunny afternoon sunbathe and generally laze of our collective gluttony in the Tea Bar wore off. After the initial inactivity, Southwold seafront suddenly burst into life, cars pouring along the promenade in an awe inspiring parade. Every type of car, filled to capacity with fully rigged boats of every shape and size, masts and sails flapping as they protruded from windows, opinion, boots and hatchbacks. The winner of this hilarious procession, in our being the brave fellow who arrived with a fleet of at least 10 fully rigged craft ranging from 15 to 36 inches in length, all crammed into one estate. In no time the lawns around the lake were festooned with dozens of yachts in every rig imaginable, Bermuda, majority of hulls Ketch, took the Square and others we were too ignorant form of fishing boats, beamy craft with deep keels and no rudders, the general to put a name to. The impression was of broad, a motley collection that did not appear to promise much in the way of speed to a family reared in the tradition of sleek radio Marbleheads. As spectators I can only presume we appeared more prepossessing than we felt for the Commodore’s son introduced himself and offered our 7 and 4 year old offspring their own boats to sail throughout the afternoons events. Papa was given a quick run down of the rules but speedily removed his anorak adorned with M.Y.A. badge in case his performance (under 7’s were allowed total assistance) on behalf of the toddlers was less than average! The fleet was divided into three classes, C 15 to 20 inch, B 21 to 27, A 28 to 36 inches. All boats allowed a bowsprit of half the boats length allowing these amazing craft to carry vast areas of sail in proportion to their modest size.

To his chagrin he also learnt that our 4 year old son can run faster than he can! In fact I’m not altogether sure my son knew that the boats were part of the racing, his total dedication being devoted to pounding round the lake at great speed. Each class set off with a 2 second handicap per inch, this worked beautifully and had obviously been perfected over the years to give very close racing and exciting finishes. Even the dumpiest of the little boats having a suprising turn of speed and size alone did not guarantee mastery of the waves.

Sixteen out of the 25 invited skippers accepted their invitations and arrived at Forest sailing water and true however, to form at New Forest, it was raining and blowing a gale, over the weekend conditions slowly changed for the better, with force to end on the Sunday 1 to 2 winds and sunshine.

Once again the standard of sailing was very high, ment non-existent. as the first day. Tony Owens won the second day although his lead was not auite so big I think the overall quality of the skippers can be seen from the fact that every skipper had at least one race in were spread between 6 different skippers. giving each skipper 25 races long distance for. the judging good and argu- ‘B’ fleet, and the fact that the A fleet wins Everyone had 11 long races on the second day for the weekend and making the event well worth travelling a During the second day there was one protest, not about the interpre- tation of rules but about the relative position of yachts at a position of 4 boats lengths from a buoy. that these All skippers were invited to sit in on the protest and it became apparent skippers who had seen the incident were divided 50-50 in their opinion. decided that there would be a match race between the two protestors, Fuller to decide the point, It was Barry Jackson and Tim and it proved to be a very close race with Tim maneging to just stay in front over most of the course and Barry making a real fight back over the last so that both boats were neck and neck for the line to push the bumper of his boat leg finishing line, Tim luffed his boat on the the two inches in front of Barry that he needed to win. Exciting stuff!! In conclusion then, an excellent weekends sailing for everyone, no hassle and lots of races. Dave Waugh can take the credit for running a very smooth meeting which in my opinion was the best event.I have ever been to. I must add that I think 16 is the maximum number that can be accomadated for an event of this type, because if all 25 invitations had been accepted we would have had to sail 320 races on the first day, and not even New Forest could do that! Perhaps there should be a priority of invitation, so that a high position in the district event, means you are asked before another skipper lower down, up to a maximum of 16 boats. For those who try and draw conclusions it should be mentioned that all the 10 different designs of boat were all tuned and set up well and that the finishing positions came about because of skipper ability and not design of hull or sails, I would bet that Tony Owens could have sailed any of the boats at the meeting and still won.

At last year’s 0.0.D. came least the fact that more entries were made suggests a certain renewal of interest and we understand that some further orders were placed during the meeting. C.W. SYKES.

Part of the answer was that I was developing the boat to handle with radio control as opposed to vane steering for which it was designed, which but the other purpose was to test several fittings I had seen lying around in certain workshops. JIB-BOOM Taking the jib first, and bearing in mind that I have always used a radial-jib kicker on my vane boats, I was attracted to the unit made both by E.L. Jones and also by Ashton Models. Very similar in layout, they comprise a through deck cylinder with a captive nut which allows a varied rake of radial post to take account of the different angles of luff for each suit of a rig. tight angle to be A stainless-steel insert in the cylinder is formed round a the fore end of the jib-boom. Mounting is via a plate screwed to the deck and an extension rod to the main load. the keelson to take Unfortunately this means that one has to estimate the position of the fitting fairly accurately. I was conservative on the first go, far aft, with the result that and ended up with it too the lower rigs of the RM had excessive flow in the jib which I could not control as the tack of the sail was some way from the boom end. A second effort was much of an improvement hole on the rach just in front of the as I got boom. the tall rig tack back to the rear Clearly no problem with a 10 Rater or even an A Class boat. Practical use shows no great problems except that water gets through the gap between plate and cylinder and of course in light-weather the whole thing is at advantage against deck. a distinct dis- the counter weighted jib booms with only a simple hook connected to the If you normally sail in working-suit breezes then definitely worth considering. MAIN-BOOM The main-boom assembly was Bantock. in fact a prototype kit for the item now sold by Graham This was assembled from the plastic bag of bits provided to see (as he put it) whether it was foolproof. The action of this unit is shown in the accompanying sketch and is based on the one used on his A boat the previous year. Apart from sail-shape control it also allows an extra length of luff which with a restricted mast height should give a small gain in efficiency, but the boom does not boat keels on follow the deck-line because it would trail in the water when the the reach and run with dire consequences. This was tried on the A boat, but meant a sail-change at each end of the lake for a whole week (vane-steering remember) and this is obviously not suitable for radio-control. In use the unit has been completely without snags, except that the bottom gooseneck pin- tle wire pulled out on mine (under tension) and I extended it through the mast forward to give extra security.

The weather mark of the course (shown on diagram) required a Starboard rounding. ‘A’ and ‘B’ approached the mark in line approximately 2 boats apart when boat mark (Ref: M.Y.A.

Boats sailed. In bearing away contact occurred, resulting by both boats. The Protest Committee ruled in favour of boat ‘A’ applying: Rule 42.2.a. Boat ‘B’ appealed (withdrawn before end of Championship) claiming that Rule 42.3.a.ii applied. The above incident was submitted solely on a question of interpretation of the rules.
