Harbormaster

Designed by Glen-L Marine

A 23 ft 2 in replica steam-era harbor launch from Glen-L Marine, a round-bilge displacement hull with tumblehome aft and a deep skeg, running about 6 knots on a 5 to 10 hp gasoline, diesel, steam or electric inboard. Built in conventional or epoxy strip planking with a double veneer skin, or in one-off fiberglass, and finished with brass and bright wood. Glen-L publish a beam of 7 ft 3 in, a hull depth of 4 ft 9 in and a draft of 1 ft 9 in.

Displacement is 3160 lb. Headroom below is 6'-3". The hull is a round bilge displacement of traditional power launch form with tumblehome topsides aft and deep skeg. Glen-L say the hull should not be lengthened. They draw a matching trailer for her. A strip-planked round-bilge hull plus a lot of finishing is patient work rather than hard work. Budget 800 to 1,400 hours. Measured medians from logged builds show below.
