Re: Bay Fishing!
you hit it on the head when you said you'll have to pick your days. Your 16 footer can get you into some good fishing, though, no doubt about it. Once I'm done rebuilding my 21' starcraft, I'm thinking of acquiring a 16 footer for the early season estuaries. If it's stripers and blues you're after, it doesn't get much better than cape cod. I belong to some other fishing related boards, and I certainly don't want to burn any spots, but I'll give you some clues as to what to look for.
Cape Cod: early season striper fishing in the estuaries is fantastic - you can fish estuaries pretty much any day in your boat - but be sure you're protected if the wind is up. It should be starting any time now. If it were me, I'd start looking on the south shore of the cape. You don't need to go far - halfway out on the cape is far enough. Again, in the estuaries. This time of year, you need shallow water and warm days. check a map for boat ramps close to shallow water and protected areas.
With a 16 footer, you'll REALLY want to be picky on fishing open ocean. but like I said, there is plenty of great fishing to be had in well protected areas - mostly early season. As the season progresses, those areas warm up too much and the fish move out to colder water.
Word to the wise: however nice it may be in the morning - it will very very likely be rougher in the afternoon. Be sure that the ramp is within striking distance if it gets bumpy out there.
