90 Ozark Deck Boat rebuild

PAR,
I have my transom made and finishing 3 coats of epoxy on it . My question is after setting it in PB should I cover the entire piece and around the sides with several layers of biax a then begin tabbing the sides. or the reverse.
Best regards
Phil

 

PAR,
Sorry should have incl some pics

 

No you don't have to cover the transom, the biax is just the "bridge", which we call tabbing, between it and the hull shell or other structural elements.

 

PAR
Would you kindly take a look at the repair to the transom and see if you feel this is adaquate. I have 6 layers of tabbing on the inside and outside corners and 3 full layers covering the entirety.
Hope this finds you well.
Best regards,
Phil

 

The gel coat should have been ground back to mat, before the new laminate went on, but I'll bet it'll hold up fine anyway. I'd also like to see the edges have fabric wrapped over them to tie both sides together. A few layers will do. Now you have a bunch of fairing to do. Keep us posted . . .

 

PAR,
Finally got her back on the trailer. I have wrapped the edges with 3 continuous pieces tying in each side. Is this what you had in mind.
Best regards
Phil

 

Yep, you've learned well Grasshopper . . . now lets see her get wet.

 

PAR,
Thanks for the compliment, keeps me motivated. Im getting ready to buy the deck materials. My local yard has APA Exterior 3/8 Fir $25.75 and yellow pine $19.97 Dont mind spending the money is the fir a better choice?
Best regards
Phil

 

You have to be careful about APA grades. There's only one that's half way good and it's "Exterior", not "Exposure 1", or "Exposure 1, Exterior". Even this stuff is marginal at best, mostly because it lacks a reasonable veneer count and internal defects are quite high. The pine will finish a lot better than the fir.

Thank you for the reply. I made sure to ask if it was APA Exterior 1. No one here carry Marine grade 3/8 however, they do have 1/2 but that would set it above the top of the hull flange.

MDO is available in 3/8" and is a slightly better grade than Exterior.

 

PAR
I thought there were problems with MDO holding a screw

 

The problem with all relatively thin APA sheets, is they don't have enough veneers. Both 3/8" and 1/2" will have only three veneers. MDO is all Douglas fir. Exterior can use a few other species.

 

Phil,
I am new to the site, and I am about to undertake a very similar project to this one. Do you still have any pics of the lay out of the deck support system you used and how did you like the results?

 

Phil was last here around 2.5 years ago, so he may not respond, you may need to start your own thread.
