More on the P5 Proa

The P5 proa is a small outrigger sailboat. It is 17 feet long overall, measured along its longest hull. It is nine feet in width overall, but each hull itself is only a foot and a quarter wide. This boat is approximately 160 pounds without passengers or cargo. It is steered by bodyweight and a steering oar, which can also be used to scull in light air. Because there is no leeboard or daggerboard the P5 can be sailed in very shallow waters.

Funding Request

CAA Allocation Request Form

CAA Application

Title of Project: Boat Building ISP (NCF Viking Association)

Sponsor’s Name: Matthew Reynolds

Date: 1/22/14

Total amount of funding requested: $535

1. Nature of the Project (thesis, ISP, study abroad, etc.)

ISP project

2. Description (goal and final product: research, presentation, artwork, itinerary, etc.)

  • The goal of this ISP is to construct a small wooden sailboat with a glass bottom for viewing of marine species/raiding and pillaging Ringling College
  • The boat will be a simple design of about 12 feet. There will be a Plexiglas panel installed in the floor for viewing marine life in the Sarasota Bay, and can be available for use at the sail club and for academic purposes.
  • The boat will be completed by the end of ISP month.


3. Importance of this specific project to the student’s academic career (thesis, increase of breadth or depth of study, etc.)

Building a functioning sailboat that can be used by the school community will be the perfect culmination of the group’s month-long efforts, and reflects the concepts and techniques taught throughout the ISP period.


4.Contribution to the student body or community?

This boat will be useful for future marine science students, and others interested in sailing and marine life.

P5 Proa

The proa traditionally is a multihull vessel with a main hull, waka, outrigger, ama, and rigging. The P5 Proa designed by Othmar Karschulin was modified from Gary Dierking’s strip planked Tarawa.

Its small multihull design can easily be transported on top of a car. It is designed to be constructed from plywood in a stich and glue method as opposed to the strip plank construction of the T2. This boat is designed to sail quickly with up to two people, but not carry heavy loads. This boat operates under sail power only, but the crab claw sail, also known as the Oceanic lateen rig, allows this boat to sail at high speeds.

The rig functions like a seesaw. By changing the bow after shunting you pull down the yard with the sail to the new bow.


  • Can be transported easily on top of a car
  • Really fast/fun
  • Is built in the easy stich and glue method


  • There’s nowhere to put glass panels
  • Only two people could sail at a time

Every plank could made from mirrored halves from 4mm plywood. The waka and ama are connected with wooden poles and the sail could be made out of tarp because it is a crab claw and does not need any shaping. With all of these things taken into consideration the P5 ends up being fairly economical to build.
