Hi UFO, I am based in Port Bouvard and been where you are in the purchase
cycle several times .
My requirements only needed up to 40 ' .
I spent a whole year flying all over to reject most of what was on offer .
You dont say if you realise the differance between the heavy displacement
apartment type Cats whose performance and ride quality is compromised by weight and hull
aspect ratio figures .
With your apparent healthy budget
might I suggest you focus on the Queensland
area where I eventually have made all my four purchases.
As above my focus is always on performance and ease in sea way handling ability.
Might I suggest you look for Grainger 50's (Chincogan's) and or other excellant Australian designers .
over polyester and believe it or not the big name manufacturers took years or never worked out that polyester resin absorbs water so be very careful of blisters
My point on performance is not only in relation to speed but the motion of the boat when underway , and to keep everyone on board comfortable happy and confident the last thing you want is a low bridge deck
slamming along trying to hold a course to windward.
Another option to investigate is the differance in dagger boards
v's fixed keels , there are pro's and con's for both ,I prefer daggers for their superior pointing efficiency however having had both my fixed keels on a Fusion 40 worked fine .
