Both will boats will do fine if not too heavily loaded and not blown up hard. A 16 ft cat is not a big boat on the MFS. When you think things are looking tight, remember that there is a rather large sweep boat not too far in front of you and there is another one not too far behind you. The cat will allow you to straddle a few rocks on the upper section.
