Raising the cabin top

Back


The inboard slope from the chainplates to the cabin top was about 3 inches.  A well pronounced hump in the side decks showed the damage from a shaky original design and over tightening of the shrouds over many years.


A previous owner had installed a wooden compression post, but it was a little on the short side and clearly installed while the mast was stepped and shrouds nice and tight.   

A screw jack was used to very slowly move the deck back into position.  The process took about 6 weeks with lots of creaks and groans in the process.  The two cardboard cores are backups so the jack could be repositioned under the mast step in preparation for installing the permanent compression post.  

The compression post is made from 316 stainless which should hold up for many, many years to come.

The compression post in place.  The base goes through to a 316 stainless plate in  the  bilge/keel.  There round stanchion base on the cabin sole is to tidy up the hole in the cabin sole.

The cabin top now measures 38 1/2" from the cabin sole to the bottom of the mast step.  This dimension came from the Cape Dory website.  Although I don't know that this is the exact dimension at the time of manufacture, the cabin top looks like it is back in place.

Our big surprise came the day we rigged Miranda in the driveway the day before her launch.  Apparently the rigging had been replaced to make up for the lower cabin top and all of the shrouds were 1-1/2" too short.  This was confirmed based on the dimensions provided in the Cape Dory manual.  Stainless tangs were added to the tops of the stays to make up the difference in the length.  As the rigging is replaced, we will use the correct dimensions and remove the tangs.
