drain hole configurations?

[Kracker Jack]

Here is what I have as of yesterday. the other picture is the style of wall or "splash well" i want to build around the sump well in the floor.There would be three half moons cut out at the bottom of the wall to let water from the floor drain into the sump well. I would also have flot switch operated pump in the sump well to pump out water.

The pic on the right is what I call a normal splashwell and is the same thing my V has factory... the only difference is that it has, and I suggest building, a floor in it that angles back to floor level at the transom and draining it through the transom instead of into the sump... then whatever water hits your deck would still drain to the sump and be pumped out.

like Maco joe said im thinking to hard. what i kinda want to know also when the boat is on the trailer how does the sump drain from rain water? i take it there is a drain plug i need to drill in that recessed sump well? I apoligize for asking all these questions but the po had the transom set up all wrong he had the sump well draining into the bilge, and the only other v20 ive been on was my dads and it was a self bailing with a higher floor.

well generally if you have a sump (V-20's don't) the garboard plug drains the sump and there are holes in the sump going into the otherwise sealed bilge that you keep plugs in while in use but pull for storage.

If my suggestions are not what you want to hear, don't hesitate to tell me and I'll stop but I suggest that you get some cardboard and build it a few times.... adding an angled floor to your "box" to turn it into a splash well really is a negligible amount of added work and ANY water that you can make self drain is an advantage..... Honestly, as high as your floor is, I'd strongly consider covering up that sump and letting your deck just drain overboard. Leave the sump to just draining the under floor area....

I agree with smoke. I can not think of any reason i would want a sump vs. a self draining deck.

Being a 74' hull I was told the floor is water level so unless I raised the floor I couldn't make it self bailing. So I installed the sump well and was gonna make it a hybrid type transom with a sump and a well type box built up. What I can do now is cover up the sump well with a piece of ply and glass it flush then cut out a circle for a 8 inch inspection plate and make kind of a dry storage in the rear. Then drill my holes for my ball scuppers and make it self bailing. The stern of this boat is lite weight and I don't think I will have a problem.

When wellcraft took this design from bilge-draining to self-draing floors, they raised the floor several inches and built the cap up several inches as well...you're saying you expect yours to be self-draining at only 3/4" above outside water level...plus the splashwell you're thinking about will only add weight in an area you don't want it...Smoke mentions having water drain into the sump to be bailed out by the bilge pump(s)...basically what I suggested early in this thread before there was mention of a splashwell...still makes sense to me...but a word of caution...WE are not there...YOU ARE...it's your boat and you know what you have in mind and conditions the boat will be used in...your craftsmanship is great...I wish I had HALF the skills you show...but the greatest workmanship won't forgive a poor design...
