Sails and Rigging


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.


Dimensions

Measure Willow Definition*
I 45.50'

Height of fore triangle. Measured from deck sheer line abeam the mast to highest point of sail attachment.

J 14.58'

Distance perpendicular from fore side of mast line to the point of intersection of the forestay with deck.

P 39.45' Luff length of mainsail measured from boom to head board in its highest position.
E 16.00' Foot length of mainsail measured from the mast to clew in its most outboard position.
P2 18.16' Luff length of mizzen (two masted boats only) measured same as “P”.
E2 6.75' Foot length of mizzen (two masted boats only) measured same as “E”.
B 15.9' (boom)  
LP   Length of the Perpendicular (LP). Distance perpendicular from the luff to the clew of the largest jib or genoa.

* Definitions from the 2003 application form of the PHRF of the Chesapeake, Inc.


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"

Storm Jib

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.

Genoa  150%

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!

Sheaves

Main Mast

Four sheaves in mast head. They are 4.5" x 5/8" aluminum. Max 1/2" line. The sheave uses an Oilite bronze sleeve bearing, 1/2" shaft diameter, 11/16" OD and 5/8" long. These are press-fit in to the sheave.

Mizzen Mast

Four sheaves in mast head. They are 2.0" x 1/2" aluminum. Max 3/8" line. The sheave uses an Oilite bronze sleeve bearing, 3/8" shaft diameter, 1/2" OD and 1/2" long. These are press-fit in to the sheave.


Shock Cord

3/16" as primary, 1/4" for heavier duty


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).
