Methods & Materials
There is no best way to build a boat. There is a way that suits the hull you want, the tools you have, the space you can spare and the patience you can muster — and the difference between them is most of what follows.
01
Stitch and glue
Plywood panels wired together and locked with epoxy fillets and glass tape. The method that has put more first-time builders on the water than any other.
Panels are cut from a full-size pattern or from measurements, drilled along their edges, and stitched together with copper wire or cable ties until the hull takes its shape. A fillet of thickened epoxy is run into every inside seam, glass tape is laid over it, and the stitches come out. There is no building jig, and often no frames: the panel shapes themselves carry the hull's form.
- What it asks
- Accurate cutting, patience with epoxy, and somewhere warm enough for it to cure. It asks very little in the way of tools — a jigsaw, a plane, a sander, clamps — and almost nothing in the way of traditional skill.
- What it gives
- A light, stiff, entirely watertight hull that needs no caulking and does not leak while it takes up, because it never takes up. It can be built in a garage and left half-finished for months without harm.
- Suits
- Dinghies, kayaks and canoes, skiffs, small cruisers — anything whose shape can be developed from flat panels.

02
Glued lapstrake
Clinker planking with epoxy in the laps instead of rivets — traditional looks with modern watertightness.
Plywood planks are spiled, cut and fitted over moulds, each overlapping the one below, and the laps are glued with thickened epoxy rather than riveted. Once the glue has cured the shell is self-supporting and the moulds come out, leaving a hull that often needs only a few light frames.
- What it asks
- Real care in spiling and fitting: a lap that does not land fair shows for the life of the boat. A building jig, and enough clamps to make a boatbuilder wince.
- What it gives
- The look of a clinker boat — that run of shadow lines along the hull — with none of a traditional clinker boat's need to be kept swelled. Light, strong and stiff for its weight.
- Suits
- Rowing and sailing dinghies, small launches, and anybody who wants the traditional appearance without traditional maintenance.
03
Clinker (traditional lapstrake)
Overlapping solid-wood planks riveted through, over steam-bent frames. The oldest method here and still among the loveliest.
Planks of solid timber are spiled and fitted over moulds, each overlapping the last, and fastened through the laps with copper nails and roves. Steam-bent frames go in afterwards, bent against the finished shell.
- What it asks
- The most traditional skill of anything on this page — spiling, bevelling, riveting, steam bending — and a tolerance for a boat that must be kept wet or allowed to take up before she stops leaking.
- What it gives
- A hull that is light, flexible, endlessly repairable a plank at a time, and unmistakable on the water. Two centuries of working boats say the method works.
- Suits
- Traditional dinghies, working-boat replicas, and builders who want the craft as much as the boat.

04
Carvel
Solid planks laid edge to edge over sawn or bent frames, with the seams caulked. The method of most traditional yachts and larger working craft.
Planks are fitted edge to edge — not overlapping — over a full set of frames, leaving a fine seam that is caulked with cotton and stopped. The result is a smooth outer surface.
- What it asks
- A full framed structure before planking begins, accurate edge-fitting along the whole length of every plank, and the caulking skills that go with it. Not a first project.
- What it gives
- A smooth hull that can be built at any size, and a structure that has been understood and repaired by boatyards everywhere for centuries.
- Suits
- Larger craft, traditional yachts, restorations and replicas.
05
Strip planking
Narrow strips edge-glued over moulds into a seamless shell, usually sheathed in glass. The usual way to a round-bilged hull without traditional skills.
Narrow strips — often bead-and-cove milled so they nest around curves — are edge-glued to one another over moulds, building up a continuous shell. The hull is then faired and sheathed in glass and epoxy inside and out.
- What it asks
- Time, and a great deal of fairing and sanding. The planking itself is undemanding and forgiving; the finishing is where the hours go.
- What it gives
- Almost any shape you like, including compound curves no sheet of plywood will take. Stiff, strong, and beautiful under varnish.
- Suits
- Canoes and kayaks above all, but also launches, dayboats and round-bilged cruisers.

06
Cold moulding
Several layers of thin veneer laid at opposing angles and glued into a monocoque shell.
Thin veneers are laid over a mould, each layer running diagonally and opposing the last, and bonded with epoxy. Three or more layers make a shell that behaves much like a moulded composite while remaining wood.
- What it asks
- A lot of stapling, a lot of glue, and a mould accurate enough to be worth building on. Materially the most expensive method here for a given size.
- What it gives
- A very strong, very stiff, entirely seamless hull with no frames needed and excellent shape-holding — the method behind many fast wooden racing boats.
- Suits
- Performance craft, powerboats, and larger one-off hulls.
07
Plywood on frame
Sheet plywood skinned over a conventional sawn frame — the classic runabout and utility method.
A full skeleton of sawn frames, keel, chines and stringers is built first and faired, then plywood panels are bent over it and fastened down. The frame carries the shape; the plywood keeps the water out.
- What it asks
- Careful frame fairing — every bevel has to be right before a panel goes on — and a good deal of accurate joinery, but very little exotic skill.
- What it gives
- A robust, straightforward hull with a lot of interior structure to fasten things to. Well suited to power, and to shapes with hard chines.
- Suits
- Runabouts, utility boats, small cruisers and the great catalogue of mid-century plywood designs.

08
Fibreglass and composite
Glass, and sometimes foam or other cores, laid up in resin — usually into a mould.
Layers of glass are laid into a female mould with resin, or over a male plug or a foam core, and cured into a monocoque shell. Building the mould is often a larger job than building the boat.
- What it asks
- Space, ventilation, protective equipment, and a willingness to work to a clock — a lay-up cannot be paused halfway. The mould makes one-off building expensive.
- What it gives
- Very low maintenance and complete indifference to being left wet. Repeatable, which matters not at all if you are building one.
- Suits
- Builders finishing a bare hull, repairing an existing boat, or building more than one of something.

09
Steel and aluminium
Plate cut, rolled and welded over frames. Rare among home builders, and formidable where it is done.
Frames are cut and set up, plate is cut — increasingly to a file supplied with the design — then pulled to shape and welded.
- What it asks
- Welding skill and equipment, lifting gear, and space. Steel additionally asks for a lifelong argument with corrosion.
- What it gives
- Toughness nothing else here matches, and the ability to take the ground, the ice and the occasional container without much comment.
- Suits
- Serious cruising hulls and workboats, built by people who already weld.
