F17 will handle 230lbs+ just fine.

In single handlers, I guess, you have to decide if you want A-cat. A-cat is ultimate boat, if you once sailed it and liked it, there is no way you'd like anything else as much.

If you don't want price tag and extra care of A-cat then there is not much difference between F17 and F16.

F17 is big and powerful and heavy. F16 is subtle, powerful and light. Both are excellent boats, there is just little different twist; you get to choose what you like most.

I’d look at local scene and see if there is any local class racing.

I do strongly recommend having a ride on “big and heavy” boats prior to purchase.(N20, F18, F17) It may surprise you how much power you are getting with the boats. You may like it, or you may want something more subtle….

Anyway, welcome to the dark side….
