As the pr.egr t,hat fits on the foot of the mast with a tension screw to give defi- nite Eitopping pressur.e. Also used a Small t.ensionometer to reoor.d amount of prossur`e exerted at heel of mast. Results were amazing. For one thing, it proves my contention that dowri- thrust is a oonverBion of forward drive, and t,her.efoz`e detrimental in effect on I.elative forward speed. I have Checked all Bor.ts of oonditionB for thl.ee weeks, taking notes. Downthrust has one beneficial result, na,mely, its help in correcting the amount of leeward movement of the hull. ‘i.Jith the gpr.ing set a,t exactly 7 lbB. pressur.e, and a wind velocity of 12 in.p.h. the pl-eBsure was found tohave a. negative effect, or By OLINTON T. SIMON in Other. words, Cancelled out the down- thrust to a point where it was equal ized by the f orwar.d hull thl.u the water. motion of the The a.mount of leeway was oheoked by the simple ex- pedient of running the hull in a lane about 10 feet wide antl GOO feet long. The amount of leewa,y was about tlmeo to f.our f eet over the length of this lane. With the spr`ing get at varying preBsureB fl.om 5 to 20 lbs. I noted a oor.r’esponding tendency to nor.e or less sidewise movement of the hull proper, in relation to the length of sure mounts, the Speed f orwal.a drops more notioibly on the beat. Kick-up has r’etar.ding ef.feet also in I.©latlve speed.The less kick-up the bettor drive obtained in light winds of. 5 to 10 in.p.h., at which point f’orward drive is cancelled by any lift whatsoever on the boom. The foot of the nainsa.il I have found. to be oo- operative with the kick-up in the boom.. They should wor.k hand in hand. This method gives a proper. aerofoil automatica,lly without a,ny guess-work on the part of the a,ttending Eil`=ipper. Thor.e iB a ra,tio however t,o be main- tained, the amount of which I still have to work out, a,nd this will be a variable fact,or in cliff er`ent areas of sail. It ha,a proven out that the jib shall always be tl.immed f or. effioiency I.ather than started. As the ar.ea, Contained therein is of such small pr.opor.Lion that it Should be used str`ictly as a, method of inorea.ging the pressure on the lee side of the mainsail. It’s pulling power is only a,bout 1/4t,h that of t,ha main, and is thor.efore not to be sa,or`ificod in or.der’ to get the speed out of the la,rse and nor.e capable sail. Also i,he jib shall not have an excessive a,mount of down-pull at the t,aok; ra.thor. let the jib lip t as it devel- rtm covered by the hull. Therlefol.e the conoluBion is that ag the amount of downthruBt i8 minimized, the a,mount of leeway is increased. However the. angle of heel had also been ohal+ has been proven in wind tunnel tests 91ng I.elative to this variance of pressure on the hull.
