Marine grade? or salt-treated plywood?
I was wondering abotu using salt-treated plywood on the Marquis deck.
I'm not a feared of paying for marine grade, but Jimmy the carpenter told me that the newer salt treated woods are about as worthy as marine grade at a fraction of the cost. So, what's the opinion? I'm even wondering abotu using hybrid decking like you'd use on a porch. synthetic mylar etc mixed with wood. The stuff is weather resistant as all get out! |

Marine ply is the same wood and glue but more layers and a solid core. Fir stands up to wet environments, unlike pine and the glue is waterproof. Exterior fir was 1/2 the price last time I did bought any. maybe 2 years ago. |

I think a lot depends on how long you expect to keep the boat, and how much value you put on your time and effort. There's no question that the marine grade is more durable over the long term and it has fewer voids.

The artificial decking that we have on our dock is quite heavy. |

Does the composite stuff come in sheets, or were you going to use boards, like this: http://tinyurl.com/29auaun I'm thinking of resurfacing my deck with that stuff. Expensive stuff though. -- John H |

It's at least 15 years old, and still looks great. Only problem is that they have sagged in places between the joists holding them up, worse than a wooden board would have in the same situation. They seem to need a little more support? Might be worth talking to a local professional about that. |

I'm even wondering abotu using hybrid decking like you'd use on a porch. synthetic mylar etc mixed with wood. The stuff is weather resistant as all get out! I looked at everything when I decked my pontoon boat 20 years ago. We had a Wolman plant here at the time and they offered to pressure treat any plywood I would bring them but the guy who ran the plant said PT really only protects it from bugs. If water is your issue, save your money. I ended up with MDO plywood (one side) and it is still going strong after 20 years in salt water. That is basically 7 layer exterior grade plywood with one MDF layer. You would probably have the same luck with BC The main thing is to be sure everything is sealed before you put it in and seal all penetrations. The only bad spot I have found in my current rehab is from an unsealed penetration. Cut all of your pieces to size, paint them on all 6 sides with 2 coats then install them. Paint it again to cover the screws. Bristol Palin will be running for president before that plywood goes bad. I worked on a sailboat once that had a PT plywood sole and where it met, the aluminium mast was badly pitted. I thought it may have been caused by the cyanic acid? |

It faces the west and gets all the harsh summer sun and the rain etc. We redid our porch twice with treated tongue and groove pine and it was rotting in 5 years. Enough was enough. This stuff is extremely durable, looks and feels and acts like wood. We've been satisfied for 10 years now. http://www.ebuild.com/product-detail...rds/319691.hwx So I was thinking of using this stuff decking the boat from side to side instead of long ways from bow to stern. Just a thought, though. |

Tim a real good grade of plywood will work fine just give it a coat or 2 of epoxy resin to seal it, regardless of what you use and by all means if you go with treated use only stainless steel fasteners or the new treated wood will eat the fasteners in short order. I think you can use acetone to thin your first coat of epoxy so it will penatrate well. I'm sure thers info on this subject at Iboats |
