Started my spring project list a little early, wanted to open it up and see what I was getting into...

I cut the top layer of glass off with a cordless saw and peeled back the sole...





Going to need warmer weather to thaw out the wet balsa core and get it clean and dry enought to replace, but I have a pretty good idea what I'm up against....Looks like 3/8" balsa core between two 1/8" glass layers...





I have enough 1/2" marine plywood to fill the area, and was hoping to use that (assuming I can clean and scrape enough depth out....) and then cover with a layer of epoxy and glass cloth...

But now that it's open I'm wondering...??


1. Can I just fill the hollowed out core with layers of glass and epoxy (no wood)...? or


2. If I cut the lip off (that forms the bildge panel opening) could I run some teak/cumaru/holly flooring panels ..."perpendicular" to the keel across the bildge side to side...? or


3. Just rebuild the sole with ply and keep the stock bildge panel covers...?

Ya might want to consider a waterproof core material like Klegecell or Divnycell, instead of wood.. For below waterline application, seems like it would be much better for piece of mind.. That is a highly loaded piece of hull .. I believe I'd repair it with foam ..

My only thought would be, is it's a heck of a lot cheaper to fill it with your plywood than buy all that epoxy. It had wood in it before didn't it? But you'll do a better job of waterproofing it than AMF did.

Ditto on Klegecell or Divnycell .... why do this backbreaking work 'twice' when your bilge 'overflows' again.

Before you commit to a method you have to determine if your cabin sole was part of the structural integrity of the boat. Many boat builders used a structural pan as part of the interior finished surfaces. Looking at your photo, it looks like your sole may be used to stiffen the hull at the keel. If that's the case, you must handle the fiberglass work as a structural repair and not as strictly cosmetic.

Started to scrape out the old and see what kind of room I have to fill...Looks like the 1/2" marine ply I already have will work in this application...





Unless this stuff has swollen that much....looks to be the same thickness as the replacement ply...

If you need to warm the wet core, why not place a cabin heater in the cabin overnight. A ceramic one will warm it up quite a bit and then you can do the work while it is still cool outside.

I have to agree with the idea of a waterproof core material. It just seems like a good idea to do this.

Got a chance to do a little more damage in the boat...


Got the sole opened up and the old soft Balsa sub floor out...





Started fitting Marine grade plywood to fill void...





Next step is to coat plywood and epoxy into soleprior to glass work...but for that I'm gonna need some warmer days/nights...my little heater warms up tyhe air enough to work but probably not warm enought to kick the epoxy...That and I want things to dry up a little more before I reseal...

Can you run a dehumidifier while boat is closed up.....let it sit on counter and then drain onto sink.....it will slightly warm the boat.... I do this on my boat and it makes for a big difference down below.... Mine is just a little 30 pint from Wally mart . It has electronic controls so you can set the humidity level to your needs Well worth the expense.

Might be a little too cool for a dehumidifier at present, they neeed 40* or better to opperate...

Up here in northern Wisconsin were still getting 20* nights, only 40* days and have 10" of snow on the ground yet...Still waiting for spring to appear...

I under stand your point ...This unit as an automatic defrost cycle. Just set it and forget...I had no problem with it freezing up this winter. And with the many other feachers and its little computer brain...Of course down here we have had a more mild winter then you up north...Back 35+ years ago I had an old sears model and it would just freeze up after it got dark....And that was in the middle of summer...It was large had sharp edges and was a real pain to store, we would have to leave it on the skinny finger pier when we wanted to go sailing. ....You would think that after you got the humidity down to a certain level inside the boat there would be less dampness in the air to collect on the coils and freeze.

Finaly had a couple days up near 60* that and a couple small heaters in the cabin and I layed in the new plywood...I coated the sole "tub" and the bottom and edged of the filler and then held in place with some weight bags...





Due to space constraints I did one side at a time, which gave me time to get everything lined in right...and held in place...I also had time to replace the leaking foot pump for the gally sink...





I ran out of epoxy, when I get my next batch, I'll coat the top of the ply and lay in a couple layers of glass cloth.

repairs below water lne

I would listen to Rich H and bad obsession Namely, avoid wood below the water line

With no disrespect to you, Rich or Bad O, If I had their money or your boat I might be inclined to acquiesce.

As it is, It's a 35 yr old boat I paid $760 for on e-bay that I've been fixing up and sailing the heck out of...If the repair lasts half as long as the original wood core (17yr) which it should, then I pretty much got my monies worth and the next guy (if there is a "next guy") can deal with it...

No problem with "wood" below the waterline if it is done right. My cockpit sole with balsa, plywood and solid glass core.

It's my understanding that boats have been built with wood below the waterline for around ten thousand years or so.

You may be alright..

Had a couple warm days (finally) so I layed up a bit moreepoxy on the sole...


I had already coated the bottom of the plywood as well as edges, then a layer in bottom of sole cavity...let that harden up...


Then I mixed a batch and poured it in the cracks and gaps around the plywood to tie everything together...I coated the top of the plywood and layed in a wide layer of 6oz cloth over the existing sole...


Then another narrower layer of cloth and epoxy to build up the thickness of the original sole.





When this hardens up, I'll sand the lumps and bumps out and be ready for the final top coat to smooth it all out into one texture...


Not sure if I want to go to the trouble of making molds and trying to duplicate the old non skid pattern with borders etc...or just dust it with silica sand in the wet top coat and then cover with paint...

You and I are living very similiar lives right now.....except here the thaw finally happened and I've been gluing my but off while the sun is still shining. The number one priority this year is NO more water from topside. 40 year old boats and wet cores just seem to go together.

happy sails

It's gonna depend on how the top coat smooths out (and what tricks I use) but I'm thinking epoxy sand and paint for now...so I can get in the water...

Depending on how it looks and lasts , I'm also looking into the vinyl-like floor coverings that look like wood but cut in with a scissors and glue down

With that shallow bildge and CB pipe stand it tends to be a semi wet floor...

Anyone have experiance with "Kiwi Grip" nonskid sold here at SBO ?

I saw some video on it and it looks like a doable option...
