The FX-One has the most hull volume of them all, its also quite a lot faster than the I17 and with your weight you will have no trouble righting it.
US version of i17 - F17 is faster than FX-1, I believe, from personal observation and Portsmouth numbers.
I'm not sure that FX-1 has more hull volume as well. Distribution of valume is different, F17 looks skinny, however it has highter freeboard and a lot more volume in bows.
I can not comment on F16, I see the boat ones, liked it, but never sailed.
F17 can support heavy skipper, and I believe, it acctually fawor heavy guys.
I would choose a boat based on local fleet and availability of OD racing. Is there any other FX1 or F17 of F16 racing in the area?
