WD 12 deck and coaming question

Submitted by Jharr - Fri, 4/21/23 » 7:14 PM

WD 12 builders ... 

When you attach the two piece deck, the bow section overlaps the stearn section leaving the bow top,  sitting on top of the stern , the thickness of the plywood that eventuly comes to zero as the pieces meet at the middle area of the cockpit.  Sort of looks like  |_  

 

Questions - can't find a pic or instrutions on this so please help

1. What are you supposed  to do with the gap area when you fiberglass? Glass all the way to the edge of the intermost deck area and then just fill the gap area with resin and then mount the coaming on top?

Or

2. Glass only to the edge of the bow deck, leaving the little overlap area in the front and then fit the coaming so it sits into that area?

 

thanks

They don't overlap, they butt up against each other, so there's no gap.

It's late here, so I'm signing off for the night, but if the answer is not clear I can try answering it again tomorrow morning.

   Thanks for responding...

Right - that's my question- on the overlap it leaves a space the thickness of the plywood where the deck piece is higher than the stern. Are you suppsed to place the cloth all the way down to the edge and then fill the space with epoxy? Or hold the cloth short just on the top piece?

Just seems weird to place the cloth all the way and fill the area with epoxy and sit the coaming on top. It cretaes an area right under the lip of of the coaming where it's just that area that was filled in with expoxy and on top of the deck (the wood)

If you pulll the coaming forward so it sits on the deck, it then creates about 3/4 of an inch on the back where the spacers and coamng are forward of the back part of the deck

No, you missed my point. Here's another picture that may show it better:

Click on the pictures to enlarge them. Zoom in. You can see that here is no overlap. The front half of the deck does not sit on the back half. The halves butt up against each other.  When they are properly shaped and stitched together the 2 halves match up and sit flat next to each other. It's a more or less flat surface under the coaming. The problem you are worried about does not exist.

If your front half is sitting on top of the back half, you're doing it wrong and need to re-stitch the deck pieces to each other. Have you put the under deck formers in place? They will shape the deck pieces correctly. See the picture below.

   OK - I see what you mean,

So - somehow then I've built my boat wrong as i do have an overlap. When assembing, it all fit and the horns fit well and the bow and stern fit well. Not 

To late now, guess I'll have to glass over the areas and see what i can do to adjust the coaming so it i get a reasonable fit. 

Here are some pics showoing the overlap and how the horns blend
