interior access ports
« on: March 07, 2018, 07:59:21 AM »
I am considering replacing the two access ports (inside the cabin just forward of the keel) with larger ones.  Does anyone have any experience or comments on what a good hatch and or hatch size would be?

I am looking at increasing the diameter of the hatch, to about 10 inches, but I am concerned about structural integrity of the decking in this area.

thanks for any thoughts you might have.

I wouldnít be too worried about it.  The loading there canít ever be very high since you canít walk on it. Fiberglass is tough stuff, especially if you have no square corners. If you are really concerned you could put a rigid backing plate under the deck before you installed the large port but itís probably not necessary.  Good luck.
