Hull preparation

With planking complete, I have sanded the inside of the hull, and begun varnishing the planking and backbone. Doing this finishing step now ensures that all the wood will be sealed properly, before I start installing the rest of the floors, frames, etc on top of the planking. It also helps me to keep the wood grain free of the dirt and dust which will be present for the remainder of the build. Now it is now time to install the remaining floor timbers in preparation for framing!

Planking complete

With the planking complete, it is time to review the review the class notes, double check measurements, and consult the stock pile of wood. Having procured the appropriate white oak bending stock for frames(or ribs) and stock for the floor timbers, it’s time to mill my stock to appropriate dimensions, and call in a friend or two to help me steam bend and fasten the frames.

Sheer planks

The last planks are ready to mount! Shaped, sanded and now drying after a pre-varnish. I seal all mating surfaces before assembly to ensure water cannot wick into the grain over the years. This is a step many larger builders often skip, because it adds extra time that you just don’t have in a high production setting. This attention to detail is one of the many benefits of custom “one-off” manufacturing.

Tools of the trade

This is my #113 Stanley compass plane that is at least 70 years old. It is my best friend on these curvaceous planks. It is a specialty plane no longer produced by high quality makers. This is one of many woodworking tools rarely seen in use outside of a few specialized trades. Wooden boat builders must search for high quality “user” tools many of them antique, discontinued or handmade.

Shaping up

Only two more pairs of planks remain. It looks as though I actually procured enough wood to make the planks from the same tree! As I close in on the sheer, I am getting excited for the next step…

Planking continues

Planking has been going smoothly. Having each plank riveted to the one below it makes the skin of the boat quite tough on its own without the need for glue. Lapstrake (or clinker) is a nice traditional method of planking that doesn’t involve toxic glue or the cleanup involved.

Plank Fastening

After the garboard planks were securely attached with woods screws, the second pair of planks could be “spiled” and attached. Each successive plank is attached to the “hood” ends with screws, and to the plank below with traditional copper rivets. No glue is needed, as the mechanical fasteners are more than up to the task, and allow for easier repairs to the hull later in life. There is something quite satisfying about driving a soft copper nail through a properly sized hole, driving on the rove (or burr) and peening until we have an effective and beautiful fastening.

Setting things up

After fitting the stem, transom and centerboard case together, it was time to setup the molds and bracing. Then I attached a few ribbands on the future plank lines so I could see the “lining-out” of how the finished planks will look. It is important to be as accurate as possible at this stage, as this is where lapstrake boats might develop an unsightly line that is irreparable.

A backbone and a strongback

With the molds and transom constructed, I next built the backbone and centerboard trunk. The wood used here is White oak and Mahogany. I could certainly use softwood to build a lighter craft, but the rugged hardwood specified by the class rules will give the boat added durability and stability.

Built to last

“When we build, let us think that we build forever. Let it not be for present delight nor for present use alone. Let it be such work as our descendants will thank us for; and let us think, as we lay stone on stone, that a time is to come when those stones will be held sacred because our hands have touched them, and that men will say, as they look upon the labor and wrought substance of them, ‘See! This our father did for us.’ ” -John Ruskin

Molds

With lofting finished, I now had full sized templates prepared for every part of the boat. This enables accuracy not possible otherwise. A fully developed lofting also provides a preview of the boat and it’s construction details, which helps me avoid unpleasant surprises. The first thing to build was the molds.

Ingredients for success

Finding top quality materials has been a rewarding challenge. I was able to source this sustainably harvested white oak log, and have it sawn into flitches for top quality planking. The folks at Newport Nautical Timbers specialize in wood for boats. Time taken to find exactly the right material for each piece of the boat is one of the things that separate a craftsman made vessel from a production one.

Developments

After I had drawn “the lines” of the hull, I drew the physical pieces of the boat. These “developments” allow me to make full size templates for each part, and insure that every part conforms to the strict “one design” rules of this classic class.

Lofting

After receiving the plans from Watersportverbond of The Netherlands (written in Dutch and measured in metric) I undertook the tedious process of converting all the metric numbers back to the original imperial measurement (measurements changed from things like: 508 mm to the more manageable 20 inches). With this done, I started to “lay down the lines”.
