M_Boats: Mast Crutch

Here's an interesting side-line on the M17: When the mast is resting in the crutch, I can't pin the base into the step unless my companionway hatch is closed. The lip of the hatch sits too high when it's open. More than once I've had frustrated friends forcing the mast against the hatch-lip, trying to wedge the mast base into the step (oy!). Fortunately, no damage to the hatch, structural or cosmetic, so far.
