Moved from a Hobie 16 to a Macgregor 26M. Wouldn't go back unless I could have both.
I was quite worried about dealing with the slower speed and it's a non-issue. The comfort and trips that I do are something that I could not do on my Hobie16. Anchoring out is absolutely fantastic - a real getaway.
A Telstar is fast but not such a great cruiser. All sailboats have their trade offs.
