The Commander has a compression post under the mast that transfers the load right to the keel. Only a knuckle head would want to change a strong and fool proof design like that!
I'm kinda a knuckle head.
In an attempt to create a roomy, private head with easy access I want to remove the compression post and put in a strongback, full bulkheads and a door like the Ariel. looking at the Ariel drawings I don't see how the load is carried to the keel. It appears that the bulkhead is relied on to carry and disperse the load. It looks like there is a vertical support on either side of the doorway, but I don't see anything under it. does it just terminate at the sole?
The manual (pg 23)shows diagonal supports, but does not show how they terminate on the lower end. Is there any additional structure not pictured in the drawings?
