Seal lauched today!

While most of the boats at Great Bay Marine are being hauled for the winter, we launched Seal for the first time today. Everything went perfectly, though we're still way above our lines because we still have about 7 tons of interior furnishings and mast, sails, food and water to add.

We plan to be in the water for about a week, commissioning the engine and testing all the mechanical systems before hauling for a winter of carpentry.

First voyage: Great Bay Marine's tugboat took us on the hip to the float, where we comissioned our engine.
