IIRC the seawards are CB boats, and will probably be good. Along with performaing better than the IP. The telstar or equal tri, like a farrier 27 will have the performance, but not sure if the cabin on any of them will be as large or nice as the IP or equal.
My choice would be the seawards or a tri. The others are WAY to slow for my needs. PHRF IIRC your SJ was 240-250, the IP is 220-230, need to look up, but it is slow, C30's about 200, the tri should be 70-80. Or at least Farrier 27's here in puget sound are about 80.
She drives me boat,
I drives me dinghy!
