    Polyurethane won't adhere very well over linseed oil. Most likely it will blister and peel.

    If you've coated the wood with the blend you mentioned, then nothing will really work well over it, and that blend will help for a while, but it's not a long term protective coating. Polyester and epoxy are not a good option over the plywood now.

    Exterior carpet holds dirt and water, it usually ends up rotting the deck.

    I lived on a lake where there were a lot of pontoon boats with carpet and the decks would rot, so it was the practice there remove all the seats, console, railings etc and then replace the decks.

    After that, they would seal them with something (I don't remember what was used) and then cover the whole deck with one big piece of rubber roofing. There was a roofing company where you could get offcuts and roll ends dirt cheap. The stuff was like innertube rubber.

    8.5' Dicor EPDM RV Rubber Roofing - By The Foot http://www.ebay.com/itm/8-5-Dicor-EPDM-RV-Rubber-Roofing-By-The-Foot-/152600053676

    That was stuck to the deck with contact cement or roof adhesive, and then the carpet was glued on top with more contact cement. Then everything else was bolted and screwed back down with plenty of sealant for the holes. The carpet could hold water and dirt and stuff, but nothing would get past the rubber roofing to rot the deck.

    The varnish seams to be adhearing to the oldtimers mixture and improves woods appearance I may use only in cabin and under wall/door.

    Varnish is not a good protective coating for the deck/floor of a boat.

    Or, you could use materials that are known to work.

    .


    "PS1-95" is the set of rules. Among the rules the suitability of plywoods to resist water damage are rated. Here's the difference between ratings of stuff that can be used outside...

    Exposure 1 plywood
    Plywood suitable for uses not permanently exposed to the weather. Panels classified as Exposure 1 are
    intended to resist the effects of moisture on structural performance as may occur due to construction delays,
    or other conditions of similar severity.

    Exterior plywood
    Plywood suitable for repeated wetting and redrying or long-term exposure to weather or other conditions of
    similar severity.

    This is what the different labels look like...

    You can get this plywood anywhere, Lowes, Home Depot, local lumberyards etc in all sorts of grades AC, BC, BB etc and thicknesses but it needs the EXTERIOR stamp or rating and NOT the Exposure 1 rating.

    You don't need this anyway, didn't you get a sheet of marine ply?

    Re-read the previous posts. There are several suggestions about materials known to work. This time, try the advise given and you should get good results.
