CAA Allocation Request Form
Title of Project: Boat Building ISP (NCF Viking Association)
Sponsor’s Name: Matthew Reynolds
Total amount of funding requested: $535
1. Nature of the Project (thesis, ISP, study abroad, etc.)
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.

|TOTAL for all items
- The dogs body is a small, fairly simple boat that was designed to be built by people who have little experience with boat building
- The boat is fairly lightweight and should be easy to construct with the same methods we used to build the Gypsy
- Clearly designed as a utilitarian boat, the Dogsbody was designed to be able to mount a small outboard motor and has storage compartments built in to its buoyancy chambers, which could be used to store any tools that would be needed in an emergency.
- The compartment on the bow of the vessel is intended for storing the fuel tank, a design choice made presumably to balance out the weight of the boat’s operator.
- The Dogsbody is a very stable, difficult to sink vessel thanks to the presence of two large buoyancy tanks located on the sides of the boat
- These tanks can also be used as benches, and as stated before have two storage compartments locate amidship
- The boat uses an eggbox construction, with the bulkheads located inside the buoyancy chambers, presumably for aesthetic reasons, as well as to reinforce the tanks’ structure and prevent catastrophic hull failures
- The design places safety and utility over performance, so this is not a boat in which one would go blasting around the lakes, but is rather a leisure cruiser, and perhaps a serviceable fishing boat
4 Sheets plywood- $90 approx

Row: Yes, Sail: Yes, Power: No
- WEIGHT: 50 lbs.
- MATERIALS: Two 4’x8′ sheets of AC 1/4″ Plywood.

I sailed these a lot back in a middle school program called HMS Crew. We used it for both sailing and sandbar/mangrove explorations of local marine habitats in Miami. More to follow! 🙂
Essentially this is the Teal from Phil Bolger’s The Folding Schooner with the deck and seats added how Tagen had suggested. It means we’ll need 1 more sheet of plywood than the 2 it calls for, but for the added utility that it brings (and the originality factor) I think it’s worth it.
3 sheets 1/4″ 4×8 plywood — $75
30′ mahogany 1×2 for gunwales — $60
50’x3″ fiberglass tape — $35
1 quart epoxy resin — $60
1 or 2 pairs of oarlocks — $15 each
10′ 1/2″ diameter round rod — $5
18″ 1/2″ diameter threaded rod — $4
2 1/2″ nuts and washers –$1
4 1/4″ eye bolts with nuts — $2
3″x3/8″ carriage bolt, nut, and washer — $1
1 gallon paint — $35
We should be able to rig the Teal with a Sunfish sail and avoid custom ordering or going through the hassle of making our own (though it would be a nice learning experience), and we could include 1 or 2 fairly sizable glass panels to the bottom if we want to go that route. It would be easy to stitch and glue it, just like our model, and its plans are laid out so that they are easy to figure out. For about $300, I think we’d be getting a lot of boat with a lot of versatility, and it would come in at only about 100 pounds, I think.
Boat was constructed by Bolger as a historical representation of an original model designed for the upper-Missouri River, which was built primarily for carrying cargo and passengers (trade, settlers) and thus did not travel fast. Older versions that carried cargo equipped to handle 20-30 crew members to propel it downstream, though this version is used primarily as a historical piece.
Constructed to navigate shallow waters. It is fitted with a square sail, but also comes equipped with oars and poles, the poles used to propel the boat along shallow rivers using human force. Small cabin in the enter, with walkways fitted on the sides for crew to stand on and maneuver the boat. Given favorable conditions, at times oars would be used, as well as the sail, though that was only occasional.
When built out of plywood it is much lighter than most other old boats, but its total displacement is mostly dependent on its cargo. Its dimensions are approximately 38’9” x 8’0”, and has a ten person capacity with accommodations (serves less of a cargo purpose and more for tourists).
- Relatively lightweight given its size
- Can hold plenty of cargo and people
- Contains multiple means of power, both human force and occasionally wind.
- Built to navigate through shallow water.
- Very large, and less portable on land.
- Doesn’t travel fast at all.
- Lot of human-intensive labor required because it can be navigated through shallow water
- Definitely not something that can be built in two weeks by the NCF Viking Club. But it is pretty interesting.
(Very Rough) Materials List:
- Plywood (pricing: on average about $5 per sq ft)
- Estimated price of hull: $1560
- Estimated price of cabin: n/a
- Epoxy (and corresponding materials)
- Glass Tape
- fabric strips to cover resin solution/glass tape
- West System Epoxy Resin 105
- West System Epoxy Hardener 205
- Wood flour (material that will harden epoxy)
- Paint (gallon covers about 300 sq ft.)
- Paint for hull: 2.08 gallons, or aprox. $50
- Paint for cabin: n/a
- Oars (15-20 oars needed?)
- Square sail
- Possible rudder
Though a keelboat would not be a suitable design for our boat, there could be some merit in having some extra space or platforms on the sides that people could stand or sit on as benches, which would leave the floor space empty for a larger glass panel. This could also increase the carrying capacity of the boat.

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.
