Plans for a Scow Moth


The Scow Moth is a wooden dinghy that builds from a kit of parts. The plans for this boat are available from Brian Porter, and they’re an outstanding example of engineering and shipwrighting skill. The drawing set provides lines of the planing hull, cross sections, and a table and curve of offsets, as well as information on building these dinghies.

The drawings can be used to build a planking or strip planked Moth hull.

Planking is the easiest way to build a scow, but it’s also the most expensive. If you want a scow that looks like the real thing (and you don’t mind spending more on your boat), then strip planking might be for you!

This type of work requires special tools and techniques that will take some time and patience, but it can be done easily if you have access to someone who knows how to use them. Strip planking involves cutting away sections of wood with an electric saw or hand saw until only one side remains attached. The remaining wood is then sanded down so that it doesn’t get in the way while sailing your boat through rough waters or into dockside traffic where they might tip over onto cars nearby – which would mean losing all their money because they do not have insurance coverage against this kind of thing happening again anytime soon.”

It is suggested that builders measure the dimensions on the actual paper plans carefully and verify them against the drawn lines, rather than blindly scale from the offset dimensions.

The plans are drawn in metric units and are to scale, but the numbers are not always accurate. They’re drawn in 1:1.5 scale and on a large scale, so they can be used as templates for construction.

For example, if you have an 8×10-foot building that is going to be 10 feet tall, then your drawing should show this size on both sides of your paper (front and back). If it’s only going to be 9 feet tall instead of 10 feet tall, then only one side should show a 9-foot dimension instead of two 8×10 dimensions like it would normally do if there were only one additional story above ground level (like in older homes where there’s no basement).Multiple Scow Moths

The hull features a wide beam and flared topsides. Many different possible ways to build the hull.

The hull is wide and flat, with a lot of surface area to hold the water. It has a very low center of gravity, which makes it stable and easy to build. The bottom of your model will be made from foam core, which can be cut into any shape you like. You’ll need foam-core strips (available in most craft stores), a glue gun or hot glue gun (for holding things together), scissors/blade knife/scalpel/exacto knife (for cutting stuff), sandpaper (if needed), some sort of sawing devices such as an electric jigsaw or scroll saw; if you don’t have access to either one then feel free just use whatever type works best for you!

I recommend using materials that are available around where you live since they’re likely cheaper than buying expensive tools from Amazon Prime Pantry at $9 each time I was making this thing.”
