Many thanks for the info guys!

I had contacted many of the Craigslist boats, but rarely get reply from the owners (like is the mast straight?). I guess they are looking for someone to drive up a buy the boat immediately. I tend to research. No internet when I bought my last boat! What a valuable tool, otherwise I would have gone out and bought another Hobie 16. Was great boat, just need more options now.
I think the cat forum advertisements are probably better kept boats and were I will concentrate my efforts.
Steve, very nice boat, I will consider it.
Thanks Turbo for the suggestions to keep the tramp clean, that is more important to me than infinite trimming options. Just the kind of practical advise I was looking for. I'll check out the Nacra F17.
Dave, I will also research the GCat, I have not seen one.
Thanks again, back to shopping.....
