[Rhodes22-list] deck shape

[Gary Novotny]

Graham,

When I replaced my bulkhead, I placed a Jack on a 2x 10 laying flat on 
the floor (high side) and used a 2x8 a temp compression post to press on 
a 8" square piece of 3/4" thick plywood on the underside of the cabin to 
raise the cabin top up about 3/4". This worked easily to restore the 
cabin to the proper height and relocate the compression post to the 
proper height.
