Thanks for the reply, although I'm still a little confused. The Surfsides I know are made from the Trillium 4500 molds, which are about 14.5 or 15' in manufacturer-measurement, which means the actual shell is about 12' long (a bit less I think). At least that's what I understand to be the TM-14
The Trillium 1300 (13') would be about 13' in manufacturer-measurements, and about 10' for the shell.
I thought that Triple E might have made some Boler
clones, but I didn't know they made any 13-footers based on the Trillium 1300 mold.
Thanks for clarifying,
