Hi Ralph:

Under mast step I have the super beefy upgrade. I has the crack parallel aft hinge on my boat inspected. Report back it was just in the gel coat. Sealed with epoxy. For compression, I recall remove the old core and replace.

These gel coats cracks can also show up at the forestay fitting; especially earlier hulls where the bow pulpit feet are bolted horizontally in doted line with the forestay bolts. Through bolt with 1" wide piece of track at port rail bolt, forestay forward (I think bolt) starboard rail bolt.
