Subject: Spar finishes

Last spring we refinished our spars, they had peeled and turned gray over the winter. We stripped the remaining varnish off, gave the wood a good sanding, a bleach wash, and then applied Cetol. They look good as new, now.

We have actually done some test samples at NorthBay Boat Works (www.northbayboatworks.com) where we finished up a spar and applied bending. The two part polyurathane actually does stretch, just about as well as traditional cured varnish. Its a matter of preferance as to maintenance. i.e. having to sand between every coat, and wait until the following day to apply another (and doing that twice a year), or being able to "wet coat" several layors on a single day, and have it last a couple of years beore having to apply another. We found that the key was using the wood sealer as opposed to thinned Bristol (with acetone)as the sealer coat. The one drawback is that patches are more difficult to apply with polyurathane than with varnish. Have to sand and feather down before appying more coats.

Interesting. I must confess I hadn't tested the finish I just went from my boatbuilding instructor who has a lot of years in the business. Oh well, learn something new every day :-)

On the matter of refinishing I have have found that once a year is fine though that probably has something to do with the fact that there is no sunshine for six months out of the year up here :-)

Indeed! I find most wooden boatbuilders stick with traditional means as opposed to using modern products. That is the case here in Sausalito as well, and is indeed the case of the instructors at the Arques School of wooden boatbuilding (http://www.arqueschl.org/)from which the owners of NBBW are all graduates. Thats why we did the tests. All wooden spars still require routine maintenance, and inspection, regardless of the finish. I actually painted the mast tops from the point of my reach while standing on the spreaders. the mast below that point are varnished with Bristol. One note: I highly recommend replacing the spreader tangs with a different design. See my post about dismasting
