I would like to tell my opinion , although it is only mine:
-If your boat is going to be a double-handed one and of the extreme kind
(extended foiler moth), then she may be a bit too small and I would try to keep the weight of the hull as low as possible ( the width @ transom do not need to be so great ).
- If you are trying to do a more" traditional" dinghy (australian skiff 14') then I would say (if its a double-handed boat) that it should go with:
1 - a lightweight crew = 130 kg
2- wings = only carbon tubes with nets.
3- a whole Displacement = 220 kg (necessitate a high tech constru.)
4- perhaps fuller lines on the forward part of the hull ( Unless your craft is going to have a bowsprit with genakers that force the crew to stay very aft on the wings and close together.
