Alberg 37 or Cape Dory 36
I have always been a little leery of Cape Dory construction quality as well. The really early ones were really poorly constructed. While they greatly improved over the years, and they added a lot of expensive details (bronze ports, nicely done interior joiner work etc.) the glass work and framing spacing never looked all that great to me.
I can''t say that I am familiar with Paul Coble but the Triton was definitely designed by Alberg. The Ariel was also ascribed to Alberg but I have always understood that the changes to the Ariel that produced the Commander (a weekender version of the Ariel) was done at Pearson in-house. Perhaps that is the boat that Paul Coble was responsible for.
