replacing styrofoam under boat floor/ marine vinyl

6 posts in this topic

I'm in the process of replacing the floor on a 16' lund boat. I got a sweet deal on marine grade plywood when menards had it on sale last month for $45/sheet for 1/2 and $69 for 3/4 inch, so I'm excited to get going on it. When I pulled the old floor up, it was quite soft and the styrofoam underneath is heavy and seems saturated. Can anyone tell me if there is a certain kin of styrofoam that I need to use as a replacement and where I can get it? I'm also considering marine vinyl instead of carpet but wonder if it gets slippery when wet. Does anyone have any experience with it? Thanks for your help!

I know that they make several kinds of marine styrofoam. I think that marine Dock styrofoam would be a good idea because it wont soak in as much water and is extremely buoyant. You could lay this in there and get a spray foam glue to lock it in, fill in the cracks, and it will expand where needed. As far as carpet I would stick with marine carpet or use a indoor/outdoor carpet.

I cant think of the name brand off the top of my head, but you need to make sure it is "closed cell" foam.

As for the carpet or marine vinyl it is just personal preference. I have the vinyl and am very happy with it. You can take a hose and wash it out very quickly. It is textured, so it's not slippery at all. We have a dog and I use the boat mainly for fishing, but occassionally duck hunting. So the utility style and easy clean up are great for that type of use.

Other's prefer the carpet which is nice too. Just depends if used for mainly fishing vs. leisure and also how dirty or clean you want to be! grin

    • Seen on the channel 5 news the other night, plans to remove a dam in River Falls. They didn't specify which dam, or if it would be both dams. The movement is gaining popularity, especially with residents. And more input meetings will be planned. However, if the project is ok'd, it doesn't sound like it will be in the near future. I'm all for the dam removal! Both of them!
    • Hey Dave, I am sorry to hear that. If you need anything you have my number.  Send me a PM or text and let me know whats going on. Recurring infection? Low blood supply?     
    • Yes. But he has a great plan to utilize the excess rail capacity in the country by relocating those who disagree with him. It's gonna be a real gas. 
    • 100% A-OK is how that's working out, but I'm not surprised by the continued confusion. Even beside Texas vs Johnson, the idea of stripping citizenship from people hasn't stood up in court.
    • You must have been on some sh*tty ice for it to do that... Love my heavy spud bar, if it doesn't go through in a couple wacks I feel pretty darn confident in stepping...Spud bar,picks,pfd,rope, common sense all ya need

    • What? You don't like the 1st amendment?
    • there is a seat belt law, why not have a ice picks law? if you are caught out ice fishing before the 1st of the year without picks, you get a "stupid" ticket.
    • So burning a Quran, or pouring bacon grease on it must be protected as well?  And flying the Stars and Bars?  How is that working out?
