I agree.. The BIM F18HT looks like a great boat.. I guess there are two designs as far as Im aware building the F18HT class.. Thats fantastic..
My choices ..
I hate heavy boats.. Too old to pick up a heavy boat.. Coupled with the knowledge that heavy boats/classes are reserved for those that cant build reasonable hulls..

So this leaves me only a few options
F16, F18HT, M18, M20, A class, B class, the C class or the D class..
D's never really took off and needs three to compete.. (would put together an 18teen if I wanted that option)
Cs.. look fun but not really any competative fleets or really for off the beach competitions..Also the 300k cost is a little daunting..

B's are another idea guess I could sail against the Tornados.. But then I could seek out a M20.. Still require two adult males to sail.. In my local conditions Ts are a handle even with the old smaller rig and two on trap..

This leaves A, M18 & F16 and F18HT
I sail solo weighing 168lb.. The local wind strength averages at 22 knots each afternoon.. Gusting between 30 and 40.. Call me chicken but Im not going to sail a F18HT solo.. That leaves F16, M18 and A.. I have a nine year old son.. He enjoys being with dad on trap sometimes.. kites are fun being a skiffie...So that takes out the A..
which leaves?
F16 and M18..

M18 could I guess be rigged with a second trap.. but I enjoy mucking about building..
leaves the F16...
