The Wood


Okoume plywood, often called mahogany plywood, is an African hardwood. It is light brown in color, sometimes lustrous, with variable interlocked grain. Okoume panels exhibit high strength to weight ratios, ideal for boat building. Face veneers are 2.3 mm thick, A/B grade, and rotary cut. Cores and crossbands are solid jointed and panel glued with waterproof/boil proof glue. Marine grade okoume meets or exceeds British Standard 1088. Okoume panels are extensively used by race class boat builders, rowing shell builders, and in various applications where its light weight, high tensile strength, good bonding properties and ease of finishing are of value. On this Penobscot, we'll do the hull planking, bulkheads, and transom in okoume.

All of the interior wood will be either Phillipine or African mahogany. The Phillipine mahogany is a beautiful honey brown when finished and will match the okoume planking nicely. It will be used as structural lumber to build the hull, the longitudinal stringers, the stem, the bulkheads, and the keel.

African mahogany is a deep, rich, burgundy-brown which will compliment the more subtle interior tones and be a stunning contrast to the white exterior. It will be used for the seats, gunwales, breast hook, and quarter knees.

The deadwood will be of white oak which is an excellent boat building wood. It is very tough and takes fastenings well. Due to its closed cell structure, which inhibits the intrusion of water, it is ideal for the one piece of wood on the boat that will remain submerged during normal use.

The combination of okoume, Phillipine mahogany, and African mahogany on this scale will be beautiful.

Our local lumber supplier quoted a four week delivery time for the okoume, so we contacted a well known boat lumber supplier in the Northwest--Edensaw Lumber in Port Townsend, Washington (www.edensaw.com). They did have some on hand and it should arrive within three to four days. In the meantime, we purchased the mahogany and the white oak as well as some pine for the frames and the building jig from High Desert Hardwood in Eagle, Idaho.

Choosing the Plans


After researching many different options, one plan in particular stood out to Tom, Sawtooth’s builder. The Penobscot 14 designed by Arch Davis (www.by-the-sea.com/archdavisdesign) seemed to meet all of the customer’s criteria, which among other things, was a traditional New England style rowing boat of lapstrake construction.

This boat is reminiscent of the working wherries and Whitehall boats that were extensively employed by New England fishermen and harbor runners beginning in the 1800’s. The glued (epoxy) plywood lapstrake construction method preserves the relationship between form and function. The boat will be as pretty as ever, but lighter, totally watertight, and easier to maintain than a traditionally constructed boat.

Tom spoke with the designer by phone and found him to be very amicable. Arch patiently answered all of his questions and assured Tom that the boat rows beautifully and can easily handle three passengers. The dimensions are:

Length 14’ 0”
Beam: 4’ 6 ½”
Weight: 155 – 175 pounds

John, our customer, liked the boat and gave us the go ahead.
