She's dressed for air! (Is that a baby swan on her tail, or a deformed
duck?) No afts ends or butts about it! It's some fowl creation... (ouch)
She sails! To windward no less....
and she motors...
she mingles with the "fleet"
A sketch in TurboCad
Kick up rudder of 1/2" ply, pivots on 3/8" SS bolt - large coffee
can lid washer acts as bearing between rudder and kick up blade.
Leading edge of rudder is capped by slit polybutelene tubing.
Rudder is lashed on in two places - top of transom and at the skeg.
Rudder head (swans head?) also faced with tubing and rests on top of transom.
Lashing is with releasable cable ties, but could be line.
25 sq. ft polytarp sprit sail - made fast to mast with small cable ties.
mast is 6 'x 1 1/4" closet pole, sprit is 6 1/2' x 3/4" square wood
rounded, 5/16" dowel at peak (goes through rope loop at sail peak) and
notch at base for snotter.
Snotter is 1/4" cord - constrictor knot at mast, with an overhand loop
"in the bite" - goes around notch in sprit - up through loop and
down to 1/2" hole in mast partner. Tensioned like a truckers hitch.
Tapering notch cut in 1/2" ply mast partner acts as a jam cleat for
snotter. (image later)
1/4" line around sail perimeter acts as down haul, and goes through
another 1/2" hole and another jam cleat notch.
Leeboard is 1/2" ply 7"x21" wetted, pivots on 3/8"SS
bolt with wing nut.
