1964 MFG Cartop 12' Resto

[sphelps]

Cool little fishing boat Cd ! Same year as my MFG only a lot smaller ..
I think I would do as others suggest . I would make the floor removable . Maybe 1/2 " ply layed flat down the the hull . Maybe Fasten some wood blocks or something like gussets down the outside edges for extra support . The span across the middle is small enough where it shouldn't need any support . . Cut some little finger holes along the edge so you can pull them out easily .. Heck its not aluminum so maybe use some p/t ply and put some deck stain on it .. Just an idea ....
Hey do you still have the MFG emblem on the sides ?

Thanks sphelps, didn't really think of deck stain that would look pretty good. I'm wanting to paint the hull a pale baby blue so that would accent it well. It does still have the metal tags on the stern area of both sides but they have been painted over, I got some nice decals I bought for it coming to replace them worst case, if they clean up good I 'll slap the decals on whatever I come up with for a trailer.

I thought you were gunna strap it to the car top ... no need for a trailer !

Ah those must have been the days, ciggerettes were unfiltered, gas was leaded, sugar was real and boats didn't need trailers lol

No Title

Here's the decals I won on eBay, for 6 bucks can't go wrong.

Got her lugged inside tonight I'll start on the Resto in the morning. Going to head to town and get some plywood for the floors, I think I'm going to go with the removeable floors. I think I'm going to use 3/8 plywood just wondering if there is a specific sort of ply I should get and for the blocks to hold the floor in I got a 6ft of 1x2 think might cut into chunks for the blocks. Any thoughts?

How long is the largest span with no support under it ... 3/8 may be a little thin ..If you are planning on painting the inside I think I would glass the blocks to the sides of the hull . That way the only thing that will be removable will be the deck ...

 

[Cdubb2010]

Maybe a foot at the most

Your call on the ply thickness . I'm about 215 or so . I would go with at least 1/2 " . What ever ya use make sure you cut it where the grain lays perpendicular /90deg to your supports ...

Update: I totally re-did my plan. The floors are cut, I attempted it initially with 3/8 ply and realized a problem that I couldn't get it to roll with the contours of the floor. So we had a sheet of 1/4 laying around and cut it to size, it seems thin but upon further review the remnants of the original floor that are still there are much stronger than I recalled. I broke out the old chunks that were busted and now I'm going to adhere the 1/4 ply straight to the old floor, covering most of the three Vs of the trihull. I'm primed the wood with coats of UMA sealing exterior primer we had at the shop and I think I'll lay carpet over it. I am pretty confident that the combined strength of the old floor and the thin ply will be good and soild for use. I haven't attempted sticking them down yet as i got more prep to do on the inside of the hull. I know a thick epoxy was suggested earlier but a friend wondered if liquid nails would work or a similar product to glue the floor down. Any thoughts? I'll have some pics up on photo bucket tommarow.

The carpet will shorten the life of the plywood a great deal because it will stay wet for a long time. 1/4" should work fine.

Gluing it down makes it a hassle to replace, and with carpet the plywood will need to be replaced sooner than without it.

 

[Cdubb2010]

I think gluing it down is unavoidable but a painted interior with no carpet wouldn't be too bad. I'm pretty confident in this primer and it's abilities but i didn't think of the carpet causing rot. I think I'll avoid the carpet upon further thought.

Paints and primers are minimally water proof at best in a situation where they are exposed to water for more than a short period of time. Epoxy is the only product that can really do much to prevent water from making it's way into the wood. And I mean real epoxy, not the stuff called "epoxy paint", they tend to be of much lower quality than straight epoxy.

Read more of the threads on this site about rotting floors and stringers, carpet is one of the leading causes of rot.

Gluing things down works well, right up until you want to remove it for some reason, then you destroy it or have a big mess to clean up, with glue being stuck to everything. Any other method of holding the floor in place is preferred to glue. I have many small boats, the ones with wood floors have nothing holding them down, gravity does a good job on its own. For small light floor panels some kind of fastening may be needed though.

I use Velcro to hold some floor sections in place, it works great on diamond plate aluminum.
