Mast base with block mounts

C&C 27's, in common with most boats of the day, don't have ideal arrangements for the numerous blocks we want to attach around the mast base. One common solution, seen on Marcus Opitz's Carriden, is to bolt an alloy "L", drilled to accommodate the shackles of the required blocks, to the side of the standard mast base. Stand-up springs are often used here (commonly with the "L" the other way up), a good idea that keeps blocks from toppling and tangling when unloaded. The stainless rods that retain the mast fore and aft may need to be replaced to make allowance for the additional thickness of the "L".
