Does anyone know suppliers of large access hatches

[Guest]

I would like to install an access hatch in the deck of my cockpit to gain access to the rear of my 1GM10 Yanmar and the shaft coupling area etc. The boat is a Marcon Striker 22ft. There is no strenghthening ribs under the deck so i would be looking for a watertight hatch within a frame which i could drop into a hole cut into the deck. I would want a fairly large hatch around 2-3 ft wide and 3-5 ft long.
Any suggestions warmly welcomed.

I suspect that you're going to need some sort of strengthening with such a big hole cut out. You also might have problems at sale time when either a prospective new owner or a surveyor asks to see your calculations.
