Building a Glued Lapstrake Caledonia Yawl

A couple Saturdays ago we went to Edensaw Woods in Port Townsend, Washington and bought the mahogany for the Caledonia.

It turns out they were out of all thicknesses of Honduras mahogany, had been out for over two months, and didn't know when their next shipment would arrive.

However, they did have African mahogany on hand. The woods are very similar in appearance and characteristics. The reason that we typically use Honduran mahogany is the grain in African is somewhat more interlocked, which makes it a bit more difficult to work with when planing. We have read that the African variety isn't as suited for varnishing due to the grain, but we haven't found this to be the case. The Shellback dinghy we have on hand was built of African mahogany, and its varnished thwarts look great. Of course, this is academic, since this boat will be painted.

There is no significant difference in weight, durability, strength, stability, glueability, screw holding, etc, so both species are widely used in boatbuilding.

We ordered the planking stock from back east, and we should have it on hand sometime next week. We used to purchase this locally, however our source sold the business. We believe that Shelmarine Marine Plywood is a superior product for boatbuilding, so we now buy this from a source on the east coast.

We're also making progress in the shop.

We have completed most of the lofting, and today we finished the patterns for the inner and outer stems and keel. We also made patterns for the rudder and its trunk.

Beaching rudders are a little tricky to build, but it's well worth the trouble.
