Notes:
- The two largest rigs have an extra reefing batten which
divides the bottom
panel in half:
- 87sf = 2 ft/2 ft
- 103sf = 2' 3"/2' 3"
- It attaches to a mast hoop or fitting like the Boom
does.
- The sail panels can be flat-cut cloth for simplicity. This is
traditional.
- For original fittings diagrams see Fittings.
- For Rushton's mast & spar diameters, see this
page.
- This is a "gunter" rigged sail. There are a number of schemes
to keep the topmast from sagging off. See Batwing
Gunter Sails. The double halyard is recommended.
- For rigging details, like where the lines go, see A
Polytarp Batwing and Reefing.
- The Upper Batten will be 1"-2" shorter than other battens to
fit in its pocket.
Cut it long and fit to suit your sail. It does not attach to the
upper mast fitting.
- Nice photos of batwing sails appear in:
- Leather, Spritsail and Lugsail, page 38, a variant
with an extra upper batten.
- WoodenBoat 55, page 82, an open Willits Brothers canoe with
a small batwing sail.
- A Canoe Called Yakaboo, WoodenBoat 119.
- Quick and Dirty Spars
- For the smallest 3 sails, use:
- Boom and Yard, 1" diameter ("closet pole", aluminum
tube, square molding).
- Battens, 3/4" diameter or similar flat stock like
"parting bead". Taper to 1/2" at leech if desired.
- For the largest two sails, use:
- Boom and Yard, 1-1/4" diameter (try "closet pole").
- Battens, 7/8" diameter or similar flat stock. Taper to
1/2" at leech if desired.
- Mast can be made out of red cedar or white cedar
"baluster", 1.75" sq by 8 feet.
- I use bamboo for spars.
For drawings of this rig’s hardware, see Rushton's
Rowboats and Canoes: The 1903 Catalog in Perspective. To set
this up as originally done requires Spar Gear No. 23, Foot Gear
No. 15, and Mast Head Gear No. 14 (part numbers from the catalog).
The sail is set with double halliards.
