Hi it is generally held that the longer , that is deeper , fin will give more fighting moment, most people reduce sail area as the wind strength increases

I used a trim tab net frisky but I use spectrum and they have a 3 position switch, I tied fairs settings but the only one I found any good was At one 3 to 5 degrees

Johns book does have some interesting designs with brief notes on why he went the way he did but, seriously the A is to me one of our most underrated classses, it does not need to be modern it can vary in weight from less than 10 kilos up to 19 or 20 kilos, and they certainly are so graceful on the water, there are some very pretty designs out there and when you consider the cost of a top one metre the A is a cheap boat, I am an ex International Canoe sailor and the A and the 6 ( my other love) are very similar.

Richard, I would say that a removable fin and a tin box would be.my preferred route it makes it much easier to change things in the future, apart from my humble opinion GB nearly always used a fin box, imitation/flattery

A litt!e aside John Lewis in s design book said Gabrielle 1000 sq in stoke for an A kind you designs then we're a fair bit heavier

Just having a look at the lines of Moby Dick, very pretty but might suffer if measured as a 6 but should be a nicely mannered yacht

Hi Richad, from tabs are allowed but my personal feeling is that they really only seem effective on long legs to windward, that's a personal thing,but you for one and you don't like it just don't use it

Hi Richard right been out and about with the tape measure ,my fine are from a renaissance and a Ravenna and both are fitted into fin boxes, total dimensional of fin 60mms long bottom of fin 290 mms long, from hull to top of lead 80 mm, length at base of hull 223 mm. the leads are .com Sails egg and are both the original shape, I believe there is a drawing on their website. do remember the draught of the yacht is set by the measuring and Carrie a high penalty in the titular so you do not want to exceed this it is determined by the overall length and the weight, I th will we some flexibility in fin depth and weight to get the best t r whatever design you have, what is it by the way. sorry it is not more straightfrward, but the penalty of this rule am a and the most of the older designs change compete with the newer designs

Hi Richard I will apply a tale measure to my sixes in the morning and get back to you, Typical sixes are from 10 kilos to12.5 to 13 kilosthe12 something is probably the common weight but lots depends on the complicated formulae

nice

What design is it

My local model shop suggested I buy direct from vape tex
