this part of the op's post I felt was important....
"I'm not looking for something seaworthy enough to cross oceans in (yet ) but if one day I wanted to hop over to the Bahamas etc, it would be nice to know that I could without having to get another boat. (with the right weather window, and a lot more experience then I have now of course )"
Of the tubs you're looking at (for the above), the grampian and bene would be more suitable... but, I'll bet by the time you want to do the bahamas thing, you'll be looking for a bigger hole to throw money into anyway, so, given that, I'd go with the catalina.
but hey, thats just me
We are not primarily on earth to see through one another, but to see one another through
Some people are like slinkies: not really good for anything... but you can't help laughing when you push them down the stairs
