Refit 3, more work

[CharlieCobra]

Here's some hull work.

Nice gash we found with some bondo in it..., sweet eh?

After another round of stripping

Hands working on varnish stripping.

such fun eh?

Charlie, Is that an FRP hull? I love the shape.

How many of your kids did you dragoon into doing work on your boat???

 

[CharlieCobra]

It's a wooden boat that was C-Flexed in '96 so she's glass hulled now.

So far, 7 of 8 have worked on the boat at one time or other.

Charlie, pardon my NC education, (We were ranked like 47th or 48th in education when I went) but what is "C-Flexed"?
Thanks
Jack

Basically, when you laminate fiberglass over a wooden boat to help protect the hull from further deterioration... See HERE.

C-Flex is a system developed by Siemens for fiberglass construction. It was adapted to glassing wooden hulls. The process is as follows.

1. The hull is completely stripped of paint or coatings.
2. Any bad or marginal planks are replaced.
3. The hull is dried out completely. (In Oh Joy's case, 90 days)
4. The planks are refastened.
5. IBM 5200 is troweled on the entire hull area to be covered.
6. C-Flex rod matting is laid up and stapled to the planking with bronze or SS staples.
7. The matting is wetted in.
8. Another layer of C-Flex is laid up, stapled and wetted in.
9. The fairing compound is applied.
10. The hull is faired and then epoxy barrier coated.

This process is used in tropical areas to both preserve wooden boats and to protect them against borers. A C-Flex job for Oh Joy would run around 100K at today's prices. The use of 5200 and the staples provides both a chemical and physical adhesion. C-Flex rod mats can also expand and contract up to 300% making the material perfect for wooden boats. This prevents delamination found with other glassing methods over wood. It also makes for a very stiff and quiet boat.

I see the Dog was quick!

Covering wooden boats with fiber glass has come a long way in twenty years.

Yeah, but I typed a lot less...

I'm just hoping the glass wasn't fractured where that impact took place. I'll be doing some closer inspection of the area both inside and out.
