Was that 1 or 5 questions?
This is a chined version of the second generation hull shape.
It is considerabley more bouyant than the earlier Blade shape particularly forward of the front beam.
The relatively flat bottoms of the hull are now converted to chines.
This should deliver even more dynamic lift off the breese. The additional fore/aft stability will allow the crew to trim upwind for min drag and the sharper bows will slice very efficiently through the chop. There is no steaming required to achieve this shape and very little fairing so building can be from either ply or foam glass sandwich. The insides construction has been significantly simplified. It is no harder than building a pair of kayaks. I found it all just good fun. But I like this type of stuff.
I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!

What many forget is ply was the most advanced high tech solution, (and with the correct skills, still is), up till the Kiwi's (Jennifer Julian) started using cores in glass boats.. The US & Europe were at that time using solid glass boats or cold molding.. The impoverished kiwis and Aussies builders could not afford the expensive materials of resin and glass. er But what they did have is many learnt the trade of building Aussie and kiwi WW2 planes. And good supplies of quality ply.
If you look around there are pages and pages of historical documents of well build offshore races built out of ply.. So the answer.. is yes a 8.5 meter cat could be built from ply if the builder has a good skill set and ply is available.. Its no longer as available as in the 70s and quality has become an issue as well..
Don't mean to thread hijack but ply 8.5s are still being built, from reading the forums at crew.org.nz a ply boat 'atttude' is one of the fastest and lightest.
You don't fancy designing an 8.5 Phill, I hear there is some interest in Oz!
