Not every owner needs that kind of speed or fuel burn. Let's go back to Asticou. Its engine is a 2003 Cat 3196B, an early electronic version of today's C12. It makes 660 hp, and with 2,260 hours on it when we visited it and Savage last fall, this durable Cat will probably outlast him. It suits the way he uses his boat very well. In our sea trial, it cruised easily, with a lovely, flat wake at 16.1 mph (1,600 rpm, 39 percent engine load) and a fuel burn of 11 gph. We had only five people aboard then, but Savage says that on whale-watching trips with 20 clients aboard, Asticou makes the 21-nautical-mile run out to Mount Desert Rock in 90 minutes, burning less than 20 gallons of fuel. For a boat that displaces 27,000 pounds, that's sailing easy.
