I agree with ncik. I would never put a port in the hull foward of the front beam. That is the area that takes the most load on the catamaran. This is just my thoughts. I don't think I would put them on the side of the hulls either. You might try drilling a hole in the center of the foward bulkhead and find a bore scope or something the will let you look through the bulk head and on both sides of the hull.
