We expect to see more of Mr. Polwin and hope he will persevere with his racing. A number of interesting fittings and adjust- ments were noted. In particular we were impressed with Doris’s out-rigged Vane gear, which carried it clear of the mainsail: the use of a celluloid school protractor on anothe r Vane- geared boat, an out-rigger of alloy to carry the extended shroudlines clear, and the clever tse of a knitting needle complete with head to carry a burgee. Altogether twelye clubs provided entries , including a father and son team from Scotla nd, who were represented by J. Cunningham Senior and Junior from Victoria and West of Scotland. These enthusiasts had travelled all night by bus without sleep but still seemed full of high spirits at the pondside. An informal supper was held at a nearby j ili cafe on the evenin g between the two sailing days, when everybody had a grand get-together. The principal were present to support the event.

The next stage consists of cementing in blocks A, B, C, etc., between the deck blocks. The position of these is readily determined from the plan (Fig. 5). The top planking is then com- pleted by the addition of a panel of 4 in. balsa, 16 in. x 3 in., with the cockpit shap e cut out (Fig. 6). When set, the whole assembly can be carved and sanded down quite smooth (Fig. 7). For the final surface finish, cover with thin silk or stout HE “Moth” as a class of racing yacht. originated in America in the early 1930’s, one of the principal limitation s being a hull length of eleven feet. The scow type hull resulting has exceptional stability for its size and, therefore, should have a parti cular appeal for modelling. The lines given do, in fact, very closely follow full-size practice. Also retained is the single sheet rig, with the mast located well forward, which may prove rather tricky in mate of the amount of rudd er required is an That knowledge will only come The model has been designed on simplified lines, so you shou ld be able to get it into the water quité soon and get in all the fitting. these deck down without wrinkles. with dope thin and This will both strengthen the wood and fill the grain ready for the paint finish. Actually, this carving and finishing is best left until the under- body has been completed as, in “block” shape, the hull has a square base to rest on when inverted to assemble the chine block s, etc. Work on the underbody proceeds as in Fig. 3. First cut the keelboard from 1 /16 in.-thick brass and outer profile lines. In plan form they are left rectangular. These are ceme nted to the ply 3 inches apart and parallel to each other. Cement in blocks F and L at the same time. The intermediate blocks, G, H.

The chine blocks are carved down to inner practice you need to master the unusual rig. When all the parts have been cut to appropriate shape, build up the uppe r hull on top of the ply false deck as shown, step-by-step (Figs. 1,2 and 4). The deck blocks are cemented to parallel. or Make sure that the keelboard is assembled over the centre line and true in the fore and aft direction. The three keel strips can then be added, the centre one being cut out to clear the keelboard and sandwiched together with the keelboard between the two outer keel strips (Fig. 8). These keel strips, it will be notic ed, finish short however, setting the tiller in a fixed position should prove satisfactory, provided your esti- from practice. applied cement and bend up two tags on the top part so that it can be screwed to the ply false deck (Fig. 8). variable winds unless a form of automatic rudder is used.

COERCRRIDGE blocks to conform to the chamfer on the chine blocks (Fig. 10). Then work over the whole of the underbody assembly to prepare the surface ready for the ply bottom covering. It is imperative that this covering seats down properly if the resulting hull is to be truly watertight. Nose and bow blocks are shaped and finished at this stage also. Bottom covering is a single sheet of 0.8 or 1 mm. ply 17 x 64in. Mark the centre line and cut a slot 34 in. long so that the ply panel can be fitted over the protruding keepboard (Fig. 11). Then score along the centre line with a pointed instrument and crease the ply into a shallow V bend. Coat the underbody blocks with cement, locate the ply covering in place and then mark round to oversize plan shape with a pencil. Remove the ply again before the cement has set, trim down to rough (oversize) outline shape with scissors, coat all jointing surfaces REDUCED again well with cement and re-locate the ply bottom in place for the last time. To clamp this assembly when drying, bind round with a length of strip rubber, drawing fairly taut so that the ply is forced to conform to the curve of the underlying blocks. Leave ample time for the CONSTRUCTING cement to set properly. Then simply trim off excess ply and shape the whole hull down to finish after adding the ply transom (Fig. 12). If silk covering is employed, make this extend over the ply bottom as well as the deck and sides. After covering and painting the hull, add the coaming fretted out of 1 in. thick wood. Detail fittings are simple. The rudder hinge is a small length of brass tube strapped to the transom with a brass strap, secured with wood screws. The rudder itself is cut from 3/16 in. thick stock, drilled as shown so that a wire spindle can be pushed through to provide a suitable hinge, and also make the rudder detach- able. Lash the tiller on a line doubled back through the three small holes shown and with each end made off on screweyes on either side of the cockpit. Instead of screweyes, incidentally, which do not hold particularly well in balsa, you can use small cleats instead. These are made from } in. dia. dowel, glued into holes drilled in the deck, leaving about 4 in. of dowel protruding. About 1 in. from the top of each dowel, drill a 1/16 in. dia. hole and fit a 4 in. length of 1/16 in. dowel through to complete the cleat.

The racing on Sunday started in a flat calm but advanced. sailing conditions improved as The wind veered and backed the day through seven or ten degrees at times and as a result some crews were dozen new new, having these, only prize list, in caught out. There were about half-a- boats sailing, or rather comparatively . been built within the last two years. Of one, “ Maid of Lorn,” appeared in the second place, and she might have done betier but for the fact that the crew are newcomers to the sport about three years ago. Their boat was one of the best im hull finish. She was from the board of Mr. Wm. Smith, of Largs, Ayrshire, and bears out, to some extent, this designer’s comment, when shown some remarks in recent numbers of the M.Y.A. News, “ Boats of my design, if properly built and handled will sail well in any weather conditions.” Mr. Smith was Chief Draughtsman with the late finm of Wm. Fife and Sons, Fairlee, Ayrshire, yacht builders. As reported in the Scottish Championship last month “ Kelvin,” the winner, was sailing and gaining prizes as far back as 1938. “ Mary Dee,” of Port Glasgow, which took third place, made her first appearance in 1950 and won the six-metre British Open Championship that year on her home waters. She also won the Scottish Championship in the same year at Dundee but only managed to run third the following year in the Scottish Championship. She was built by her owner-skipper, Mr. Alexander Smith. Racing finished at 6.45 p.m. when Mrs. Wm. Logan, wife of the Scottish judge, handed over the Cup and prizes to the successful competitors.

Tie for third place were D. Barber, of Southgate, with ‘“* May II” (who won the sail-off) and E. Croxford, of Lymington, with “Calypso,” each having 464 points. Other leading scorers were as follows:— * Ailsa,’ R. Fry, Hove and Brighton, 43 points. “ Anguila,” J. Cocken, M.Y.S.A., 39 points. “ Blue Belle,” R. F. Searle, Ryde, 39 points. “ Carol,” G.

The Mayor presented the Cup, and prizes to the first, second and third place skippers (with souvenin crested forks to their mates), and on behalf of the Borough Council extended the wish that the visitors would return next year. ; On both days the competitors were entertained to tea by the Ryde Club. Bournville Model Yacht and Power Boat Club For more than 20 years six-metre model yachts have been entered fon the annual contest to win the Sanderson Silver Yacht Trophy. Tie A good entry of ships provided many exciting heats and the final result redounded to the skill and enthusiasm of the popular Sailing Captain of the Club, Ron Harris, who was followed closely by Allan Davis, winner of several previous trophies. An exceptionally encouraging performance to the officers who have been giving him instruction was put up by Junior John Kellagher. aged about twelve years. The Commodore placed “Una” at his disposal and by diligence, John proved the lessons he had learnt from Mark Fairbrother, the Club Secretary, and from W. H. Ray, Commodore, by finishing fourth. man of the M.Y.A., Mr. Charles R. Seabrooke, who travelled to Glasgow from London specially for this event. Results:— 1, Mr. Wm. Brown’s “ Kelvin,” Dennistoun Club, 79 points. 2, Mr. J. McCallum’s “ Maid of Lorn,” Alexandra Club, 73 points. 3, Mr. A. Smith’s “Mary Dee,” Port Glasgow Club, 63 points. 4, Mr. Hector McNithan’s “*Saramac,” Paisley Club, 60 points. The prizewinners were all fin-and-skeg models as were most of the other competitors. The second and third prizewinners used Vane steering gear and the first and fourth Braine gear. Leading scores:— 1, “ Ethel,’ R. Harris, 61 points. 2, “ Dare,” A. Davis, 59 points. 3, “Dainty,” J. Ward, 45 points. 4, “Una,” J. Kellagher, 41 points. Yachts of the 10-Rater Class were engaged in the gontest for the Mr. and Mrs. Edward Cadbury Silver Yacht Trophy on 11th October. A strong S.E. to S. wind created excellent sailing conditions and there were several individual races won by the merest margin. Allan Davis did remarkably well and again Junior John Kellagher put up a distinguished performance’ emerging with points equal to the class yachtsman, George Leeds. In a deciding race for second place John lost to George and so finished third.
