If building a new boat, the 27’ makes a lot more sense, which is probably why the 25’ is so rare. Hull cost is $700 more for 2’ extra hull, that’s a bargain. Both boats would cost the same to finish, power, etc. And I bet the 27’ is more efficient than the 25’. No brainer. The 27 and 29 H&H’s are nice boats and have a lot of volume for their length.
