Well it really depends on how long you intend to be down there. If you are just passing past the capes, then I think that would work. Would not be my first choice, but I am a bit more traditional in taste. But if you are going to spend much time down there take a look at Skip's videos in the Yachting World series. If you plan on doing extensive time down there then yes I think it would make sense to look at a purpose built boat, or at least something with some protection. I would want someplace to get out of the inevitable weather at least.
