Gqlifornicr Redwood for Bocrls

To determine the suitability of California Redwood for boat construction insofar as buoyancy after long immersion in water is concerned, John Reno, utilization engineer of The Pacific Lumber.Company, continuously floated in water pieces of both flat grain and vertical grain kiln dried Redwood which had been carefully measured and weighed.

The tests were much more severe than conditions that would be experienced in actual practice. The samples were 25/37' thick by 3f" wide by 6' long, which means that end grain, with its much greater porosity, was present far beyond what would be encountered in boat construction. This end grain absorbs water quicker and to a much greater extent than the side grain, and any tendency to become waterlogged would be much greater in these short samples than in longJength boat lumber

When originally placed in water October 5, 1953, the pieces were without any coating or finish. It was thought this would be a severe test, since there was no sealer .on the pieces to of the pieces only.

It was thought this would increase the severity of the test, since the water would have free access to the uncoated bottom and ends of the pieces, but the evaporation from the top faces would be retarded.

Finally, on November 8, 1954, after a total of 13 months' soaking, the pieces were removed from the water. They still floated freely. There was little difference in the effect of the long soaking on the vertical grain and flat grain.

This test supplements a previous one in which multiple matched pieces of kiln dried Redwood and Western Red Cedar had been carefully weighed and then immersed together in water. After 48 hours' soaking, they were removed and promptly weighed. Both had picked up about the same 'amount of water which showed the absorption to be about the same in these two generally used boat woods.
