Without seeing the specific boat it is hard to tell what the specific repairs
would be required. There are a number of aft cabin layouts on the Morgan Out Island
51 but on the most common layout the mizzen mast appears to come down on the cabin top adjacent to the longitudinal bulkhead at the head
of the 'tub/shower'. If the mast has sagged into the deck this is potentially a very big repair. To begin with the mast would need to be removed and the mast step removed from the deck.
If the 51 is constructed the same way as the 41, I believe that Morgan
cored the deck in this area with plywood
. If the deck has sagged it is highly likely the plywood
has separated from the fiberglass
laminate and the plywood probably has some rot
and splitting. To get access to that area the glass would need to be cut away, removed and built back with epoxy
On some Morgan
layouts there is a post that is below the mast step and on others there is a simple longitudinal plywood bulkhead. The bulkhead and post are wooden and glassed to the hull
. If the bulkhead or post shows sign of movement then they are more than likely no longer properly bonded to the hull
. This can be a very serious problem. The cabin sole
would need to be removed in the area to get access to the bilge
and the joint between the hull and the bulkhead, and post, with the hull. If the bulkhead or post is rotted in the bilge
(a very distinct possibility) they will need to be replicated and glassed back into place.
In the worst case this is a very major repair if you consider the costs of getting access, making the repairs
, perhaps replacing the bulkhead and post, and putting everything back. This is especially true if you factor in the costs of finishing the new work areas.
But, and this is a big 'but', when you say that there is a mast step problem this may be as minor as replacing the maststep fitting which would simply require removing the mast and constructing a replica maststep.
Depending on the reality of the situation it could be a little as a couple grand to as much as $10-15K.
My best advice would be to get a surveyor
or an experienced boatyard manager to look at the damage and give you an estimate and whatever that estimate comes out to, I would allow as much as 50% to 100% more for surprises and aggrevation.
