I apologize in advance for the vague subject line. As I read the following I realize it may be difficult to follow, please feel free to ask for clarification, no offense will be taken.


I need to know if the bump in the deck just above the rubrail on a 41 Marinette is solid or not. This bump up is to assist in the channeling of water on the deck to the rear of the boat. The problem I am having is that the water does not fully drain from this channel and I have about 6 inches of water about 1/8" deep that accumulates on the boat on a daily basis. It is on the NE side of the boat and the sun does not get there at all to dry it out. The water has accumulated at the extreme rear of the boat and has lifted up Awlgrip paint. Awlgrip rep claims this is an issue because Alwgrip top side paint is not designed to be under water. I need to get this water to drain out fully.

I was planning to cut a small kerf in this bump to allow the water to fully drain out. I need to know if any one knows if this bump is solid or not. If I cut the kerf and bump is not solid then I will need to fix the cut and then go to plan 2.

Plan 2 was to put a small drain hole in the deck and route it to the hull to drain over board. I am not sure of the access to this area from the inside. I have already removed the failed Alwgrip paint and need to repaint this area. I was thinking about a 1/8 inch drain hole.

I would also appreciate any information any may have on this and additionally if anyone has addressed this issue in some other manner.

Thanks in advance

Minn.Dan,

I’m not positive but I’d say it would be a solid piece of 1/2 round stock ahh it just came to me take the
smallest drill U own say a 1/16" & drill thru depth of the round where U plan on cutting the kerf but not the deck U’ll soon find out if it’s hollow or not. If & when U do this chore how about letting the rest of the forum know the out come so we don't have to do this

Norm,

Keep your hooks wet & your Butts dry also make sure your whistle stays wet

For just this small area, consider using a different paint that can be kept underwater - epoxy bottom paints are designed for this.

I almost didn't find this post this evening....

I was rooting around on my boat a bit earlier and found a couple of cross-sections of hull construction laying in the bilge area under the forward bunk. I guess these were used as sales tools back in the day to provide some detail on construction. Just a guess. I took a couple of quick photos. Will try to get some better ones later. This cross section of the extrusion with deck and side pieces welded in should answer the question concerning what is under the 'bump' on the deck. The other cross-section appears to be the keel.

Awesome photos!
When I sanded the deck to raw aluminum it looked to me that my had a red rubber between the deck and the upper part of the extrusions U. This coud have just been a thick primer coat but the only place I found it was near the rub rail. Either way it would seem that welding eiher side would have cooked either material away.

Thanks for taking the time to post the pictures. They are like Xrays.

Now, that photo I can understand. The other ones are still confusing.

Thanks for posting!

"There is another class of coloured people who make a business of keeping the troubles, the wrongs, and the hardships of the Negro race before the public. Having learned that they are able to make a living out of their troubles, they have grown into the settled habit of advertising their wrongs -- partly because they want sympathy and partly because it pays. Some of these people do not want the Negro to lose his grievances, because they do not want to lose their jobs." Booker T. Washington

Yes...great!
Norm dosen't even need his quad-focal glasses.

My topside deck was not welded though. I've got that red rubber stuff on top and too much black crap underneath to tell if it was welded there. Maybe it's just JB Welded together...

drilling a hole will cure the problem of the water standing i to have this on my 32 but the hole needs to be big enough so that it does not clog up with just normal dust and lint the drain holes in the front of the 32 look like 1/4 but they still clog with dirt and spiders, if you do put a hole in it make it big enough for like a #3 an fitting x 1/8 npt and put the fitting up from the bottom to flush off with top skin with a little piece of screen in it and then you could plum it to any drain you wanted fitting woud be 1/8 npt male by #3 an male (3/16) and also would be aluminum

dont drill ! ! i have a 32 with same issue what i think you need to do is as fallows buy a 45 gallon keg of C/M spiced rum and a spunge and put the keg on affected aria so she sits lower in the water then i will come by and sop up the standing water and drink all your rum repeat as neccary
