The TCBW 21 Runabout is a complete new construction from the plans up. I was contracted by a local business man to build him a classic utilitarian runabout style boat that he could use for waterskiing, clamming, ferrying people from the beach to his sailboat as well as evening cocktail cruising in Nantucket Harbor. He also wanted to look out of his window at his house on the water, at something more aesthetically pleasing than his current 17ʼ Boston Whaler. After browsing through the Wooden Boat Magazine plan section, we settled on plan #WB142, “Pretty Marsh 21”designed by Doug Hylan, Brooklin, Maine.
The hull is made up of 3 layers of 6 mm (1/4) Merrenti Mahogany plywood on the sides and 2 layers of 13 mm (1/2) Merrenti on the bottom for a total of 3/4”sides and 1”bottom. Each layer has been epoxy and vacuum bagged together. The entire exterior of the hull has been covered on 10 oz fiberglass cloth and System 3 Epoxy and then vacuum bagged. The spray rails and keel are made out of solid Honduras Mahogany epoxied and covered with 10 oz cloth. The interior stringers are 3 layers of laminated 13 mm Merrenti and there are a total of 4 main stringers. The cockpit has seating for 6-8 adults comfortably. The owner of this boat wanted a Port side helm configuration for his own personal needs but any layout is possible. She is powered by a 150 Yamaha 4 stroke outboard and has a cruise speed of 30 knots and a top speed of 35.5 knots. The building process went very smooth and turned out a great looking and fantastic performing runabout.
