Default Re: 1972 20 CC Complete Restore

Made the switch from plywood... 1.5" penske for the transom and corecell for the deck. Got it tabbed in yesterday, its rock solid already.
Poured foam in the stringers, and got worse at it on each one. How does that even happen? I gotta say that is amazing stuff to work with.

First pour






Picked this bad boy up from home depot, its like a jet engine and gets the garage toasty.

Looking at these pictures I am feeling encouraged. I will own my dad's '72 20' before too long and when I do I'll have to tear out the floor. Fortunately it's simply a matter of removing the rivets behind the rub rail and lifting the innards from the hull. I don't have my '73 Shovelhead to tear apart any more, ride a BMW now. So I'm looking forward to getting personal with the boat. Looking forward to seeing the end results, Yours and Mine.

Grinding with those 36g pads is so easy, its practically a roto-tiller- just gotta watch touching the foam... At least it doesn't make any dust though.

After raising the stringers and laying out the corecell, its gonna be about 17 or 18 inches from the deck to top of the gunnel (at lowest part close to transom). This seems super low standing on the boat now... I know its not a tall boat but are those measurements regular on other 20s?

Your restoration is coming along nicely! Keep up the good work. As far as the freeboard goes, the 20 doesn't have much to begin with and by raising the height of the stringers you will decrease it even further. 17" sounds about right though mine may be less than that.

Default Back at it- 20 CC

update... made a dolly to roll in and out of the garage- works like a charm. 3 sheets of corecell for the floor, with woven- one layer from each side, overlapping in the middle. its strong but i haven't convinced myself not to add one layer of 1708. other than that fitting the tank underneath and sanding...

**if anyone has a heated garage bay or anything let me know, i'm sick of being outdoors/ the cold weather is slowing progress.

I like your roller base. I made similar base but the rollers must be too small because it is not easy to move. What size rollers did you use

Thank you

What kind of resin are you using? It's very red.

Ed, we used to build these things to display new boats in our showroom, and quickly learned that anything less than 6" wheels on the casters created problem. We finally settled on using soft rubber 8" casters, with locking/swiveling casters at both ends, and carpeted bunks. We also used 2"x8"x10" PT (or Wolmanized) bunks, and added a cross-brace in the middle to prevent horizontal bowing.
