23' Tremolino T-Gull 23

A very rare, well maintained, factory-built, 1997 Dick Newick designed folding trimaran. One man mast raising, opening of amas, and sailing with 30-40 minutes setup time. This Tremolino folding/swing wing trimaran is in very good condition and has recently had numerous upgrades to modernize the vessel its ready to sail.

Boat has been stored on the trailer, covered, and launched for each sail at marina, so no extra wear from being on dock or mooring. Most of its life was sailed on a freshwater lake, I recently sailed her in the Pacific Northwest but have washed the boat and trailer of all salt water afterwards.

Asking price $18,000 (including delivery within 1,000 miles of Northern Colorado)
