plywood recommend

junoir woody,thanks for sharing info.i appreciate all input,knowledge is power.i did learn from your link,thank you.i was just poking fun at the god reference in one of the posts.when people feel the nedd to inject a little faith into everything it gets under my skin,i hope i dont offend.thanks again.

If exterior fir plywood and the same size/grade in marine plywood were the same price, would marine plywood be the better choice?

Hey bishop,

It would appear that the fir with a layer of cloth will suit your needs. As a matter of exercise only I would suggest that you price the cost to purchase and send ply to your home from Bateau. It may well exceed the budget. Just good to know the difference to make an informed decision.

The forum at Bateau is a good one. Though I haven't participated I shall as soon as I start the building of a Phantom 18. I ,purchased the plans and marine ply to build her before my son found the 1950 CC we are currently working on.
as with this site, I have found the members for the most part are very willing to share and always mean the best with their advice. I do enjoy reading about their fishing adventures also.

Jack,
I don't feel you are comparing "apples to apples" here. Again, please understand we are talking about ply with glass on it for a floor in a no foam hull and some bulkheads and not hull sides or bottom.

As mentioned, CC used Fir ply for it's painted hull sides and bottom. I have NO problems with the typical Fir checking problem since it was CPES'd and this is without glass. Fir ply no matter what grade it is, will check.

The poster should have used some CPES to bind the outer layer of Fir veneer together.

The original foam backed up the glass cloth. in it's absence the ply will take over the support it offered. therefore it needs strength and longevity. I'll let this one rest for now I promise.

I have a hankering to get back to work on the stem but life gets complicated at times. Mama needed a new kitchen and then there's that little cottage in Florida that beacons this time of year. don' fear Pete, I will return to the utility soon and there will be pics. Need to dust off the topic.

Hey Pete, Just saying here that the the deck could be built with 3/8 in. Marine ply for a couple hundred bucks. This would provide a good base for the glass as it is a scaffold which bears some structural responsibilities. Please don't underestimate it's importance.

as always thanks for the replies.greg,i think you got me straightend out.i realize it doesnt have to be pretty.this stuff looks much nicer then the regular 3 ply exterior and its halfthe price.maybe i'll buy a peice this week and post a pic.

you would think that attached to the plywood that it would be waterproof, its not, i belive at the time i too did research on marine ply and found out that it was the final finish that was the difference and for its intended purpose, it did not warrant the extra money...i believe it had the name attached and as everything with the label of marine on it....you get twice the money,
but, i will to do some more research Sheldon and get back to you

easy now,pete doesnt want us new guys getting lazy with free answers.i assure all of you i have been researching and taking notes for a year.this site is by far the best resource i have found.greg's rebuild on his BFN used fir plywood which i thought was listed as cabinet grade.my question is regarding the glue.if what i found at $26 a sheet is infact cabinet grade fir can i use it?

x4, lol

$96 a sheet .not happening

several people have mentioned that marine ply is a waste of$$$$

Just curious here. Why not get a sheet of marine ply?

thanks guys.label says made from fir harvested in northwest.i'll look to see where it was actually made.too bad this particular HD is in the city with a not so knowledgable staff.
