well, that's pretty much what I'd use it for anyway out here on the Gulf, although chop may be problematic?
I know the A class has a bit of a bad rap when it comes to boats/masts being "fragile", but how bad is it really? I'm not (or at least try) going to crash into docks, but will the mast handle the occasional flip?
I have a 13 year old boat that was and is still 6 pounds overweight. I still get good results with (split 2 races with Harper last weekend). It's all original and I fear no wind with it. Do stupid things, get stupid results. You do need to be more diligent with releasing the downhaul downwind but its still a durable boat.
