My Friend has 36 NB whose bomar indeck hatchs are raised up just enough to scupper water away from Hatch. (Keeping water out, and of course no water gets into material.ie wood.My new deck will have no wood, but still want water to scupper away.) I plan on having my hatches raised as well, but have no idea how they did this. My friend bought boat, not a builder so he's out as far as info. So anyone here know how to raise hatch just enough?
