I need to purchase the wood for my floor. Not going with marine plywood cost is too high. I need 3/4". What would be some good options. I am thinking 3/4 bc with epoxy on bottom, polyester glassed and gelcoated on top. Thanks! |

| Exterior grade ply is just fine. 3/4" is overkill... 5/8" should be more than thick enough. 1/2" may even be fine depending on how you support it. I'd put a layer of cloth on the underside, and a layer of cloth + mat on the top. |

I done mine in 3/4" cabinet grade ply. I cpesed all sides then covered all sides with three layers of 8 oz satin weave. Overkill yeah, but my floors are solid as concrete when walking on them.lol ------------- “Tact is the ability to step on a man's toes without messing up the shine on his shoes.” ― Harry S. Truman |

Wil, Go with Tim's recommendation. I agree with him however I question you using polyester resin and not epoxy. Regarding Vic's cabinet grade ply, yes, it's way overkill and the extra weigh is why his boat is so slow!!  BTW, at least he CPES'd and epoxy /clothed it since cabinet grades are typically not bonded with waterproof glues. They are made for interior use.------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

| We used exterior fir AC 5/8" for our 1st boat, and marine 5/8" for the 2nd boat which turned out to be beautiful mahogany veneer plywood. Probably much nicer than it had to be, but it has 11 plys, no voids and is really solid. Probably cost 3-4 times what fir AC exterior grade costs, but you only need 3 sheets. |

Pete. To correct you the ply I used indeed does have the marine glue and doesnt have the voids in the plys that exterior grade has. No voids equals less chance of water intrusion. And as for as slow......well if you want to keep up with me Ill gladly throw you a rope, as thats the only way your atom bomb or your all original tique will do it. Lol Also on a side note last I checked most cabinets have sinks mounted to them so even though its interior its still subjected to moisture. And as far as weight, my boat actually lost a pound or two. No foam remember....I dont remember the axact weight the tique is supposed to be but weighing it I do remember it was a few pounds shy of specifications. Any way I put my two cents in, no need to hijak his thread. ------------- “Tact is the ability to step on a man's toes without messing up the shine on his shoes.” ― Harry S. Truman |

What does the APA mark show? Post it please.
I'll run my X55 against you any day we meet up!  What does you Tique GPS at? "Atom bomb"?? Give me a break Vic!! Sounds like you're cutting down my Atom which BTW has won several best of shows at sanctioned ACBS events.
Tell me of a cabinet maker that uses exterior grade ply? Manufacturer?
Add up the 3lbs per cu. foot and compare that to the extra weight. Hijak? I thought the thread started with ply for the sole?  ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Pete. Number one the apa mark is buried under layers of glass and carpet now and it doesnt matter because I have to prove nothing to you. Number two. I have GPSed 54.0/54.5 so if that ole gray will keep up good for you. Number three I have no reason to insult your boat even though you opened your mouth hinting that mine was slow. number four. I dont know of any cabinet maker using exterior ply. Im sure he would be using cabinet grade ply. number five. I dont care about the weight even if you care to arque with me that its more. I weighed the boat against what it should of and it was a little less than spec. And the hijack is you referring that my build was inferior because I didnt use what pete said to. The OP wanted opinions and what folks here had used and my two cents was delivered.I think the OP wants info not arguements hence hijack ------------- “Tact is the ability to step on a man's toes without messing up the shine on his shoes.” ― Harry S.

CPES is not original Epoxy is not original Laminating the floor bottom is not original or even hot coating it for that matter. Sealing the limber holes isn't original either. Or tapered prop shafts, CNC machined propellers or Gortex packing. Crappy old plywood and polyester is what it was made with. Use that. ------------- Jesus was a bare-footer............. |

Glass and epoxy over 2lb foam makes a solid, lightweight floor. And yes, I know the arguments. Consider this though; that nasty foam is the first thing we see when the old floor comes up and that's where much of the water is as well. No wonder it gets a bad rap. I used fir ply(1/2 & 3/4) drenched in CPES for the secondary stringer system and the bulkheads(all vertical, mostly I copied what CC did). I spent some extra time fitting the pieces after a lot of time prepping the hull so I'd have something to fit to, and did the peanut butter and wonder bread thing carefully. Also, I used the pour method so I had to sand the uneven surface to make the floor flat. The sanded(open cell) surface took a fair portion of epoxy before I started laying glass. The compartments held water before they were foamed. ------------- http://correctcraftfan.com/diaries/details.asp?ID=2331&sort=&pagenum=12&yrstart=1986&yrend=1990" rel="nofollow - 1988 BFN-sold "It's a Livin' Thing...What a Terrible Thing to Lose" ELO |

I used 5/8 BCX ply for my 64 and my old 68 cuda. A little less cost than AC. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1117&sort=&pagenum=6" rel="nofollow - 64 American Skier 62 Classic.. 73 Ski Nautique |

Just a simple thing to do... when looking at ply check out the glue lines for a dark brown/red looking glue ( Resorcinol Phenol Resin) as it’s the best type of WBP ply the cheaper ones tend to be made with melamine glue (Clear Looking) still WBP Ply but will delaminate in less than ½ the time of Resorcinol. ------------- Lets have a go 56 Starflite 77 SN 78 SN 80 BFN |

Wil, Roger "nailed" it as far as telling what the ply bond is without the APA ID. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |
