Have you nothing better to do HO2 !
There are only one or two that are simular to what I will be building.
I will use carbon and high denticy closed cell foam.....as I want strength and low weight.
My vision is that it will be a slopping carpeted hinged ramp that will be adjustable by the davits and possibly can take the tender.
Unfortantly I have enough jobs at the moment so it will remain in the design ,beer and bull**** corner for now.
