1979 19 ft Sea Ox rebuild

[Mr Pamlico]

Stringers look good. How far apart are they and how thick is the hull between them?

They are 30 inches apart. I am not exactly sure the thickness of the hull there. I don't know of any way to measure it without drilling a hole. I think I am leaning towards putting one there just to be on the safe side.

I do not know if you need the center stringer or not. But I know you think you need it so I would add it in. But then I tend to over build just a tad

Good progress!!! Jeff

The last picture is where I am at right now. I got that center stringer glued down last night. I plan to start tabbing it in tonight. I then need to cap the stringers and tab them to the transom. I will be doing that with 1700 as well. What would yall recommend for the capping and the tabbing to the transom? They feel pretty dang solid right now. I wasnt sure if I needed to cap them being that they are composite but I'm sure that would add to the strength even if I just do one layer. The gas tank pad is glued down and I plan on putting one layer of glass over it too.

[Mr Pamlico]

I just looked back and saw where fallguy recommended capping with 3 layers of 1700 so I will plan on that. I just need to figure my tabbing to the transom out. I figured when I cap the stringers and the glass is still wet I would go on and tab to the transom at the same time

Nice work!!! Jeff

I would tab stringers to transom 8",6",4" both sides at a minimum. 1708, not 1700, largest tapes first

1700 is fine...no need for 1708. If you've got it, use it.

I'm not a huge fan of the stringer butt joints nearly lining up across the hull. A larger stagger would be preferred...but that's just me.

Sure, but for me, I'd then use four 1700 tapes to get the same or similar weights/thickness. The only reason I default to the 1708 is less work. If you don't have it; that creates more troubles.

1708=25 oz x 3 = 75 oz
17 x 4 = 68 oz

It's my firm belief that the mat adds less than 1/2 the strength, and uses nearly twice the amount of resin. I've not read this entire thread (to be honest I skipped from page 1 to this page...the last page as I type this). If the OP is using poly, I won't say not to use 1708...but if he's using epoxy, then I stand by the '08 being a waste.

And I would absolutely use four layers of 1700 for those stringers.
