Westcat,
Where are you located? That would help in directing you to find boats for sale or try out. Crew weight is fine! I have sailed against another F16 w/ 1-up weight of 140lbs in very windy conditions--no problem but does take skill. Smaller sails okay per the rules, but you won't need them--F16 rig is so tunable you should be able to depower when needed.
