Re: Super Maramu Rear Cabin - Proposed New Top hatch
We get great airflow thru the aft hatch. The secret is to close all the other hatches and leave the companion way open. A wind scoop definitely helps at the rear hatch and on light wind days we have a fan mounted on a board in the hatch.

Regrettably, Bali Hai was lost in the Atlantic near the US shore when the crew abandoned her.
Here are some photos of an aft cabin hatch install on a SM. I do not recommend the wooden outside spacer used in this modification. If an external spacer is used I believe it should be fabricated from GRP.
That coach roof is balsa filled, so any penetration should be done by experienced people and care should be taken that the exposed balsa in sealed correctly.
