The folks at Pjoa.eu have a nice Christmas gift for us: plans for a plywood-epoxy stitch and glue version of their beach-cruiser sailing proa:
Let us proudly share that we have made available an extensive plans set for proa PJOA FOLK. By “extensive” – they contain e.g. step-by-step building and rigging instructions. Knowing where a lot of proanauts find significant problems, we want to save them a lot of time, so another part is soon…
Here’s another cool project from Harryproa:
The mini cargo ferry was designed in response to a need to replace the outboard powered fibreglass skiffs which are ubiquitous in the Pacific. These boats are expensive to run, difficult to maintain and have almost completely destroyed the islanders boat building and sailing skills.
Taking a step back to near stone-age construction materials of plywood/epoxy, the boats are as…
The Camel of the Sea is a sailing multihull cargo vessel designed for operation by a small crew of 3-6 in areas of steady winds and expensive petroleum. As outlined in The Case for the Cargo Proa, physics favors the proa configuration in the case of widely varying displacement. In this example, the fully laden boat weighs over three times the boat when empty. To recap the argument:
Widely variable displacement on multihulls is a…
Coconut is a 24’ sailing fishing proa being built in Honokaa, Hawaii by Tim Mann, for employment in Micronesia as a lagoon taxi, fishing boat and small copra hauler. She is a proof of concept for Tim’s vision of “carbon-negative” modern technology vessels competing boat for boat against the gasoline-powered craft now so ubiquitous in the islands.
“She’s lashed together. Outboard-hung kick-up rudders lash onto the boat also; when they…
Rael Dobkins from Balkan Shipyards has a new proa rig - a clever Chinese lug or junk designed for shunting. Rael hopes to combine all the traditional benefits of the junk rig, such as being easily reefed, single-handed, and cheap for the DIY crowd, with the requirements of shunting. Stay tuned to his channel to see how it all works out!
Thanks To Robert W. for the link.

Harryproa has an interesting cargo proa concept: an inter-island ferry/cargo vessel for East Timor. The brief calls for 10 tons of cargo and capacity for 25 passengers, primarily (but not only) wind propelled, a crew of 2, shallow draft and beach-able, built and repaired by local semi/unskilled labor with minimal equipment and easily obtained materials, and a large tender.
Naturally, Harryproa has determined that a harryproa is the…
Praocargo 12m model on Vimeo. Cargo vessel could be the role the proa configuration will claim as its own.
Shipping may be the most energy-efficient mode of cargo transport, but small ships transporting less than 4% of world cargo contribute 26% of all shipping emissions.
Advances in racing technology give us the tools to design a boat that is fast, light, and able to sail close to the wind, allowing us to open up sailing trade…
Jan Stute and Siegfried Wagner have designed and built a modular camp-cruiser proa that was recently exhibited at Hanseboot in Hamburg. The design is based on a classic Pacific island sailing canoe, or walap, including a crab claw sail and deep-V asymmetrical hull, though realized in modern plywood and epoxy. The hull comes apart into three sections to make storage and transport more flexible.
We like the optional canoe dinghy, which…
Harryproa has been busy of late. Here’s a nicely modeled proposal for the new VOR Inshore Foiler races. It is, naturally, a proa in configuration, but that is where the similarity to a Pacific sailing canoe ends. The fully foiling triscaph may be vapor-ware at the moment, but considering the obvious thought that went into the proposal from shipping logistics to VIP guest seating we hope this one makes it to prototype stage. Read Rob…
French designer Jérôme Delaunay has completed plans for a 9.9m (32’-6”) cruising proa named VAKA 990. It is a “pacific” type that includes four berths, a WC and some storage. The proa features a free-standing schooner rig of 37.25 m2 (400 sq. ft.) and central daggerboard in the main hull. Steering is via outboard mounted (Viking-style) rudders fore and aft. The central accommodations pod extends out to leeward to function as…
