Addison –who choreographed a pirate jig for the occasion — was the youngest person on board.Don Berry, 79, on a field trip with Glennwood Place Senior Living, was one of the oldest. Passengers of all ages seemed to enjoy the three-hour battle sail as the Chieftain and the Lady Washington pelted each other with gunpowder shot from three-pounder guns.But the crews who spend days and nights for weeks on end in close quarters at this work, were downright jovial.Eric Ahlvin from Corvallis, Ore., known as the “boat papa,” balanced on the ropes high above the water, casting gaskets to unfurl the sails.His son Teddy Ahlvin, the bosun in charge of everything from the deck up, was busy ensuring all the lines were working as they should.
