I found some 4.5" adhesive-backed rolls which worked pretty well -- they were about $15-20 for a 30' roll. I believe the brand was Porter-Cable. What really helped extend the paper life was using compressed air to clean the surface every few minutes. Of course that only works if you are outside in a reasonable breeze (pretty common here in coastal NC) and are standing upwind!

Here is a shot of the underside of the plate — a shout out to VT_Jeff from whom I stole the idea to bevel the underside of the plate:
Nice use of the beveling and of the objective case!
There are only two seasons in Vermont: boating season, and boat-building season.

I've finished adding the "top hat" style cleats to bump up the sole by 0.75" or so. If I ever used them again I'll pay a lot more attention when putting in the stringers and frames. The GV15's stringers and frames are just a single layer of 3/8" ply so don't go in perfectly straight unless you take care (which I didn't). Just a bit of wobbly (1/8-1/4") means the slot in the top hat cleat needs to be opened up. I had cut the slot on a router table and then cut them to length before I discovered the wobble issue. I spent about a week opening up the slots with a chisel. :help:

Now onto finishing the chase tubes and cutting the floor panels. I picked up a sheet of 3mm ply along with the 12" Meranti ply for the sole. I've been using the 3mm sheet to make a pattern for the final cut. Here is the first sole panel pattern and cut Meranti sheet:

When you're ready to think about that new, bigger boat build, contact me & I can put you in contact with someone who cuts one heck of a jig for an awesome Carolina 25 hull. It won't be stitch & glue, but rather a cold molded boat. You'll have all the skill you need by then. And they are local to you & me here in NC. I won't post any links or mention the designer here out of respect for Bateau.

What is the best way to seal around chase tubes coming up through the sole?

All foamed and sole is in place. Rain is forecasted for tomorrow so I rolled on a quick coat of epoxy to seal it all up.

8367

Up next, fillets and tape to firmly attach sole to hull and then a layer of 6oz. cloth. Sure is nice to be able to walk around inside without stumbling over stringers and frames!

Looking good Brian!

I think most seal the tubes coming up with either thickened epoxy or some type of flexible caulk.

Yeah, I found this post from Jacques that lays it all out:
jacquesmm wrote: Wed Jul 01, 2020 10:36 am ...Epoxy does not bond to PVC pipes. At those points, your pipes must extend above the sole by a few inches and they must be sealed where they go through the sole. You can seal with 5200 or you can build a fiberglass sleeve all around to the top of the pipe. Think of the PVC pipe as a lost mold. To just glass a small lip around the pipe is not sufficient. Even with the methods above, if water gets over the top of the pipe, it will flood the pipe and go somewhere....
Are there alternatives to 5200 that aren't so gooey and sticky? I'm hesitant to use something not rated for the marine environment.

It has been awhile since my last update. Boatbuilding was on hold for a few months but is now going again. The sole is covered in 6 oz. woven & the motor well bulkhead and casting deck frame installed:
8936
8935

The cut-outs in the motor well frame to the left and right of the motor well are for a pair of passenger seats and double as steps to the transom / side decks.

Next up are the above sole frames with cut-outs and the bow locker. I'll be posting a separate couple of threads on those to get suggestions / guidance from the forum.
