You might want to consider the Nacra F17. It sails well with 2 people, with or without the optional jib kit, but is raced single-handed without a jib. I think it is probably more durable than the F16, is a foot and a half longer and weighs about 320 lbs. Based on your statements, it seems a better choice.
The attachment is a picture of several F17s on the beach.
WOW, thats 90lbs heavier as well. Foot and half is 18" so that boils down to 5lbs of weight per inch in length.
Why is it called an F17 anyway? I asked this question a while back and no one gave me a straight answer.
