T-20P Cruising Proa

This was my final Project at The Landing School. For this project, I didn't really have any restrictions; I chose the proa because I knew it would be a major challenge and would afford me the opportunity to grow a lot. The biggest challenge I faced was finding any information about proas on the internet; this proved to be very exhausting. The few details I did find on proas are based primarily on observation, mostly from sailors who have seen or sailed one. I set out to design my hull based on my current knowledge of hydrodynamics and hydrostatics. The second big challenge was finding space inside the narrow hulls for my dream of a lavish interior space. After spending weeks working out the kinks in the hull shape through many long nights doing CFD resistance runs and making minor tweaks to my hull shape, I finally was able to start working out the interior details and machinery layout. This proa also conforms to ISO design category A for aluminum scantlings. It has a large (125 square meter) Solar Sail attached to a carbon fiber unstayed AERORIG. I worked out the bending moments and inertia. A large 10 LiPo battery bank, a 9Kw generator, and three HVAC units. This proa has one 40KW electric engine, can sleep 8, has two heads with attached shower/saunas, and a ton of open space.

Here is a render of the foredeck looking aft at the cockpit windshield.

This is the dollhouse render of the upper decks. On the ama side, you can see the sunken lounge, two deck hatches for access to AMA berths, a large deck area including two sun lounges on either side and a massive seating area on either side of the dual wheel pedestal helm. Past the helm are two bi-folding glass doors, a large six-person settee with a folding walnut table that converts into a double berth. A spacious galley on the right with a five-burner cooktop and large oven, a large stainless steel sink, two faucets, and two drawer fridges. On the right is the office area with two drawer freezers.

This is the dollhouse render of the general arrangement and mechanical arrangement. On the AMA side, we have two single berths and closets accessed on deck through deck hatches. Between them is the machinery room. In the middle is the 40Kw electric motor. On either side are the sleeping pods. Past the pods are the large staterooms with reading nooks, bars, showers/saunas, and large heads.

This is my favorite render. It’s a shot from the windward side of the AMA onto the deck. Here, you can see the dual-wheeled pedestal and compass, as well as into the deckhouse at the settee.

Here is a render of the galley from the office side of the settee.

This is a shot of the office and bar from the galley side of the settee.

Here is a closer view of the nav station/office area.

This is a render of the top stairs leading down into one of the massive staterooms below deck; you can see the shower/sauna room. You can also see the majority of the galley and counter space.

This is a render of the head-looking midship into the shower/sauna and the stairs leading to the galley.

Here is a shot of one of the sleeping pods from the landing just outside the shower/sauna.

This is a shot from one of the sleeping pods looking at the reading nook and bar. I imagined this would be a great place to read while underway, just watching the water rush past you so close.

This was a nice view from one of the sleeping pods.
