Subject: Mast step fiberglass compression issues

WIth or without the reengineered mast support on bulkhead, decks crack thwartship just aft of the step, parralleling the hinge of the step.

Is this where your step is cracked; or all around??

Rigs racked aft just do this . . . one solution is rocker the front edges so the rig can rock forward under compression.

Cracks first issue;. water damage that will destroy the plywood core under the rig; allowing the rig to smush down even further. Lacking reengineered structure, and with water damage, this is how rigs have broken through deck and original structure.
