Centerboard
Centerboard pennant -- Winch handle 5/8" drive socket, 7x19 302 stainless steel wire rope, 3/16" diameter, 22' long. Wire replaced in 2006.
The bronze handle is made by Merriman. It's about 6" long. The drive socket length is about 2"" and its OD is 1".
Chocks
The stern chocks were 5". One broke (2001) and I replaced it with a stainless steel 6" chock.
Cotter Pins
The standard cotter pin sizes on Willow are 3/32", 1/8" x 3/4", and 5/32" x 1". A rule of thumb for cotter pin length is 1.5 times the clevis pin diameter.

Dock Lines
Willow carries a traveling set of dock lines:
Four 40' x 5/8" 3-strand
nylon with a 12" diameter eye on one end (new 12/2006)
Four 25' x 5/8" nylon double braid (new 6/1998)
Genoa Track
Merriman 1¼" wide track, 3/16" thick
Gooseneck
Vertical pin -- 15/32" D x 4 11/32" L, 9/64" cotter pin hole
Hydrovane
Model VXA 1D M/EH. Installed 2007.
Hairpin cotter pin for rudder attachment: wire diameter 0.062", eye diameter 5/16", length 1-5/16" (McMaster-Carr 92375A152). Pin substitutes -- Ring-grip quick release pin: 1/4" diameter, usable length 3.5" (McMaster-Carr 98404A155) (need to drill cotter pin hole).
Outside pipe diameter of vertical shaft: 2.0" Lifelines
3/16" wire with vinyl coating. OD of 5/16". In 2003 I replaced the forward lifelines with New England Ropes T900 ¼" line. The cost was approximately 1/3 of wire. After one hard season of 2,600 miles, the lines show no wear or fraying.
1" OD stanchions held down with ¼"-20 x 1½" carriage bolts, 6" x 4½" x ¼" aluminum backing plates, lock washer, and nut. The backing plate is epoxied to the bottomside of the deck. The holes through the deck are countersunk and I used 4200 caulk. I ground the stanchion holes square with a Dremel and a tungsten bit -- about 10 minutes per stanchion base.
Miscellaneous
Use 3M 101 in Sta-Lok fittings.

New 2006, UK Sails, Annapolis, MD. Luff tape 7/32"
Hood sail, R(?)54372, never used. Eight hanks grommets plus a sail tape for a luff groove. The grommets are set back1 3/8" from the luff tape (i.e., 1 3/8" from the grommit edge closest to the luff tape). I sewed in webbing and sail hanks for raising the sail on the inner forestay. The tack should be 18 to 24" above the deck.
Hood sail. 5.9 oz. material. According to Banks, it should be 7.3 oz. They estimate (8/00) that I have a year or two left with the material, but no guaranteees about going offshore!

Spinnaker Track
12 ft. x 1¼" silver track (Schaefer). The spinnaker car is a 17-84 from Schaefer. Installed 2003. The goal is to store the whisker pole on the mast to ease handling it and to free-up deck space.
Whisker Pole
11.92' to 19.75'. 2" and 2.5" diameter (OD). Made by Arco (no longer in business).
