“Sonata is project number 648 of the prestigious American naval architect John Alden. She was designed by Carl Alberg in 1937 and built in Boston, Massachusetts in the F.F. Pendleton shipyards. She is a cutter sloop, 15 meters in length, with 3.60 meters in beam and 1.95 meters height from keel, ideal for shallow waters. She has 15 tonnes of displacement of which 6 are in ballast and a sail surface area of 114 square meters.
Structurally speaking, she is built with the so-called double hull with keel and classic ribs. On this is a double lining of planks making 32mm of thickness that are covered so that its seams do not provide openings, thus eliminating the need for caulking. The first interior lining is of red cedar and the second of marine mahogany. This lining is connected with the keel by several 40mm thick solid mahogany garboard strakes attached to the keel by caulking. The Alden design has harmonious shapes and very delicate sheer. The American was a master at creating vanishing lines between this curve, the cambers of the deck and deckhouse and the different elements of the tackle resulting in incomparable harmonies.”
