That's what makes trailer-sailers interesting: their keel swings up into a "trunk" inside the hull. With the keel retracted they can safely beach, and sit in a very low profile on a trailer. MacGregors and a few others feature water ballast that is drained at the ramp when the boats come out to lighten them for trailering.
They also have a relativley quick way to take the mast down and trailer it fastened to the top of the boat.
