Sean...look thru this Gallery at what Emmet Fitzpatrick did...you'll see a barrier fixed onto the front of his splashwell that prevents water from coming into the boat...will stop it in the splashwell...I've cut a similar piece for mine, but haven't finsished installation...this may be something for your consideration...
