G'day,
 
Before you do anything rash, there should be some pictures and build instructions of my new ww hull for a 50' solo race boat on the next web update, due soon.  Worked pretty well although there are a few things I will do differently next time. 
 
Not sure yet whether we will be changing the designs, but if you don't want or need any fancy 3 dimensional curves it is a very quick way to build hulls.  Took me about 8 hours actual work (fair bit more than this making mistakes and thinking) to get two half hulls and decks ready to join amidships.  With some cutting and shutting, more elaborate deck shapes will be possible.  Under water shapes are fine as is.  Not sure whether the cutting and shutting will be more or less work than KSS, but as they are only along one axis, and this is on the deck so it is easier to conceal, less critical to fair and should be less work.
 
A KSS workshop would be a great idea.  Learn about infusion, table making and tricks for getting panels how you want them, even if you don't use the actual KSS technique.
 
regards,
 
Rob

I'm hoping to use a modificaton of the KSS system of derek kelsal
using polyprop honeycomb. I have made a couple of 1:20 models in
cardboard-of a Harry using the half hull technique and managed
something pretty close to the design as I remember it so it seems
plausible. Rob is playing with polyprop at the moment and he and Mark
should have some idea of the practicality of the idea, though I don't
know how keen he is about once again having to modify the designs to
be able to use the technique and i am not sure of the ethics of not
slinging a few dollars dereks way for his intellectual effort.
Possibly going to one of his workshops would be a good idea.
regards
Robert
