Boat kits and plans are available for rowboats, kayaks, sailboats and motor boats. The decision about what type of boat to actually build depends on the builder's skill level and temperament. Various websites, either hosted by boat designers or by design brokers, allow potential boat builders to see what's available.
One example of a boat designer that offers kits and plans is White Salmon Boat Works. The company ships all the pieces, ready for assembly, for rowboats, canoes and sea kayaks. Builders with more experience or who simply enjoy a challenge may opt for a basic boat kit that has pre-cut plywood forms, resins, hardeners, fibreglass cloth if appropriate, instructions and the boat plans.
Wooden Boat is an online magazine for boat lovers and has a section featuring boat plans and kits. Each listing has a link for more details on the craft and a web address for the boat designer. It also lists the skill level needed to build each boat.
For example, the Petrel Play kayak, at 14 feet long, is made of fiberglass and wood, and comes with a full kit or with just the wood parts included. It requires intermediate building skills to complete. Beginning boat builders can also try their hand at building the Wee Pumpkin, a mini-boat that's actually a cradle. The designer sells the plans only for this project.
