Sailboats are slow, but large sailboats can be heavy. That boat displaces 22,000 lbs. dry (no fuel, no water, no provisions, no accessories or equipment). In a sailing configuration it can easily reach 25,000 lbs. Move 25,000 lbs at 7 knots and you are carrying a lot of force. In crash Diesel fuel is safe as it's flash point is much lower than gasoline. The good news is that a person moving at 7 knots in a crash probably has the strength to hold and stop himself with no serious injury unless he is at the point of impact where the crushing fiberglass would seriously hurt him. sailboats do have a keel that protrudes from the bottom of the boat and depending on the depth of the water it could slow or even stop a boat as it grounds. This boat has a Draft of 6 ft. and that keel has weight of almost 7,000 lbs or 1/3 of the total displacement of 22,000 lbs. It keeps the boat right side up. In case of crash the boat could jump up or get crushed against a jetty up to where the keel starts. No fiery crash like a power boat, not likely to sink as held by the jetty and very survivable unless the man set the autopilot and went to sleep in the V-berth at the bow.
