Cal 20 Restoration 3

The seventh set of Cal 20 Restoration Pictues is now available at

For reasons unknown, we soldier on with our Cal 20 restoration. This week, we finished the epoxy repairs on deck cracks and points of damage, and then we did a complete sanding of the entire deck before the first coat of Interlux Primekote primer.

At that point, we made a mistake and didn’t add 20-25% thinner, and as a result the primer went on like spackle. The quart covered less than half of the deck, and the vertical areas had pretty terrible brush strokes. It took four hours of sanding to flatten everything out again.

We then used two more quarts of thinned Primekote and completed two complete coats. Then we sanded a little and painted on two coats of Interlux Perfection Mediterranean White. It dried with a much higher shine than we expected, even if a bit “whiter” than we hoped.

Now we’re working on deck hardware, wood and fittings. We’ve found that a portable planner is literally recovering warped wood that we thought was ruined. The washboards and mounting wood all planed out flat and pretty once again.

After that, we’re doing 5-6 coats of VC Tar2 barrier coats before the VC 17 antifouling. We hope to launch on September 10th.

Here’s the link to the sixth set of restoration photos:

During the last week, we Easypoxied the interior, finished the ceiling repairs, fabricated and installed new plywood supports under the cockpit, scrubbed and sanded the deck, opened and patched cracks in the deck, did final sanding on topsides and below waterline, cleaned and waxed the boom, and wire brushed the hull/deck joint. We also ordered deck paint, a used North Sails jib, and new gunnel rubber (from Steve Seal).

This week, we plan to finish deck prep, prime the deck, do two coats of Interlux Perfection on the decks, re-install deck hardware, and then begin the epoxy barrier coats below the waterline.

Some questions for knowledgeable Cal 20 mavens:

1) I need to order or buy new running rigging. Does anyone have any recent measurements for correct lengths of lines needed? Also, we need to figure out how the mainsheet is supposed to be routed between the pulleys on the side decks, the end of the boom, and central pulley in the middle of the aft deck.

2) Is it safe to have a remote gas tank under the cockpit seat hatch? I noticed there’s a notch for the line, but it seems like fumes from the vent would go into the bilge area. On the club boats we sail, the remote tanks are always in a locker that is sealed from the bilge.

My brother and I purchased a Cal 20 that needed work, and we’ve posted five sets of photos of our progress so far. The latest set is available at

Links to the previous four sets of photos are at the top of page.

So far, we’ve dropped and refinished the keel, and reconnected it with stainless keel bolts. We’ve prepped the hull for epoxy barrier coats, and over the last three days we’ve prepped the interior and primed it for Pettit EasyPoxy. Next weekend, we hope to finish the deck prep and paint it. All hardware is removed, and we’ve begun work on crack repairs.
