John "Shiraz" should not leave a sour taste in the mouth but rather a full bodied one with a peppery after taste.
I have one question which is not specific to your design but relates to the newer flush deck hulls. How do they drain water from around the mast base or do they not concern themselves with it? Well that is two questions really.
David has Porky Pig been turned on a lathe to gain the circular sections? It looks like a turning centre in your photo.
The challenge with any NEW design is competing with the tremendous amount of R&D that has gone into an established design. Many of us know how difficult it is to tune any new boat. Best wishes to all the new hull designers for a successful campaign." May you always be on the correct side of the lift."
