The Corsair 13 is a sturdy but performant small sail boat, ideal for two or three people but easily handled by a solo sailor. Complete with mainsail, jib and spinnaker, she is an excellent introduction to technical sailing.
A versatile sailing dinghy for 2 or 3, the Corsair 13 can also be sailed solo. Easy to build, easy to sail but with enough performance potential to satisfy experienced sailors.
Very able, strong but light, the CR13 can take some bad weather.


Experienced sailors can outfit the Corsair 13 with hiking straps, tiller extension and a trapeze. They can customize rig and deck plan to fit their preferences.

Thanks to her wide transom, she can be fitted with a very small outboard or an electric trolling motor.

Options:

The plans show different spar materials. The standard rig is an aluminum profile with two alternatives: a wooden mast and a carbon fiber one.
Specifications are given for each one.

The standard rig totals 102 sq.ft. but a spinnaker of 80 sq.ft can be added.
Each sail plan shows the sheet, blocks and all details needed to rig the boat plus exact sail, running and standing rigging dimensions.
The spinnaker well is optional.

The Corsair 13 can be made unsinkable with buoyancy foam poured in place under the seats and deck.

All these options can be combined to customize your boat: build her as simple or as sophisticated as you want.

Building method:
The CR13 is built the Sharpie way: two sides panels are bent around a frame and joined at the bow and the transom. Bottom panels are stitched to the sides and fiberglass seams are build. The building method is exactly as shown in our stitch and glue basic tutorial. No jig is required.

Required Skills:
The Sharpie assembly method used on this boat is the easiest building method, identical to our Flat Skiffs , see our tutorials for pictures.

The plans include full size patterns for all frames, transom and a bow mold. All dimensions are shown on the plans including the side and bottom panels: no lofting required.

All the dimensions for the sails and spars are shown on the plans.

The CR13 can be build by a first time builder.

BOM:
The plywood layout was calculated to minimize waste: we show the nesting of all parts on the plans. The spars can be made from plain spruce boards, 1x3, laminated.

Plywood 4x8' (122x244cm)
1/4" (6mm) 4  
3/8" (9mm) 2  
1/2" (13mm) 1  
Fiberglass (Totals)
Biaxial tape 77 yards 69 m
Woven Fabric 9 yards 8 m
Resin
Epoxy, total 4.5 gallons 20 liters

Labor:
The hull with deck and seats will require on the average 40 hours and another 40 hours will be necessary for the appendages. A first time builder should not overlook the amount of labor required to build all the parts related to sailing: daggerboard and trunk, rudder etc. Our plans are very detailed and the fabrication of those components does not present any difficulty but the finish of any sailboat requires more time than the building of the hull.

Cost:
Meranti 6566 is an inexpensive type of marine ply ideal for stitch and glue construction. It cost, on the average, less than $80.00 a sheet in 1/4" (6mm). Okoume or Meranti marine can also be used and cost starts at less than $100.00 a sheet (1/4").
