I think you have some pretty good options mentioned above.
Elkrun mentioned hewscraft boats and they are some fantastic boats for the uses you mention, unfortunately they are not exactly cheap (especially the searunners) and almost impossible to find used.
I have a 17 Arima SeaRanger. Great boat for the sound and strait and close off shore stuff.

Piper, as to your question of what size I was refering to, it is very important to know which of the two, the blonde or brunette, has a wider beam, what their draft is (how deep they go) and if the flotation devices are adequate for your needs!!
