The theme for this year’s Tuning Day on Saturday, February 22, is “Tuning”. Tuning is the act of adjusting the lengths and tensions of your standing rigging, i.e. the wires which support the mast. Because your mainsail is attached to your mast, and your jib is attached to your headstay (which is part of the standing rigging), rig tuning affects sail shape. If your mast is not centered athwartships, or your mast is shaped other than straight when sighting up the mainsail slot, your boat will not sail the same on each tack. Raking your mast aft by lengthening the headstay will increase windward helm, and help you point higher at the cost of stability. Outer shroud tension sets headstay tension, and thus headstay sag, and is the one adjustment you might see being made prior to a race, especially if it is expected to be very windy.
How important is rig tuning for Harbor 20 racing in Newport Harbor? If the setup is not just wrong, probably not that much. That is because we don’t do a lot of long legs where a tenth of a knot of boat speed can make a difference. Properly playing one wind shift, or gaining an inside overlap at a mark makes a much bigger difference. But, you are competing after all, so your boat should be setup properly. We will show you how.
What do you need? To measure mast positioning in the boat, you need a tape measure longer than 30 feet. To adjust your turnbuckles, you need a small wrench to keep the wire form rotating (a small crescent wrench or vicegrip works well), and a screwdriver to turn the buckle. It is easiest to tune with two people, one on each side of the boat, in which case you will need two sets of tools. You will also need a wire tension gage (Loos Gauge), but these are expensive and we will have several on hand.
We will also be talking about sail shape, and the adjustments which can be made underway. One adjustment which many people cannot make easily when underway is the height of the jib in the headstay. Use of two fiddle blocks, as shown here, makes it a snap!
The fiddle block is a Ronstan Fiddle Block with V-Jam, RF341. West Marine Part 110884.
Every sailor should know the basic knots which can get you through a lifetime. They are the proper cleat, the clove hitch, the rolling and taut line hitch, the bowline, and the c-gasket to secure a coil of line. If you can demonstrate each of these knots, you will win a prize. If you cannot, we will teach you the knots, and then give you a chance to win.
10:00am Welcome sailors. Boats secured on the docks.
10:30am Tuning Tips- Peter Haynes and Bill Menninger give a brief review of rig tuning and sail trim under various weather conditions. The Schock Factory will be participating in the Q & A.
11:15am Lunch available to eat on the patio or dock.
11:30am Boat tuning and repairs begin. Experienced sailors will be on the docks to share tips and assist with tuning. Loos Gauges will be available for shroud adjustments.
2:00pm Tuning Day concludes
Lunch and Refreshments are compliments of Fleet 1. (You must RSVP to receive Lunch and Refreshments)
The Schock Factory will have many parts for sale so we invite you to work on your boat repairs during Tuning Day. If you share your plans for any unusual on-site repairs, we will inform the Schock Factory in advance.
Please RSVP no later than February 19th: Michael Volk, email@example.com
The tuning day article says “One adjustment which many people cannot make easily when underway is the height of the jib in the headstay.” This implies you’re allowed to adjust the jib height during races, but the class bylaws say you can’t in Class Races: “II.C.5. …All crew shall keep their torsos within the confines of the cockpit at all times, excepting in the need for immediate repair or for safety.” I think adjustment between races is fine as long as you don’t fall overboard (which I nearly did in Annapolis last summer).
While I can see how you might interpret this to mean that it implies you’re allowed to adjust the jib height during races, I was careful to use the words “while underway”, instead of “while racing”. The point I was trying to make is that it is hard to work on that skinny bow, which is the only option if not tied up at a dock.

Hear Hear – The 5 wise men wanted a highly tactical boat that was relatively insenstive to the myriad of tuning nuances found in other classes. They 5 wise men were successful in their goal; don’t get obessesed with rig tune at the expense of missing that wind shift 🙂
great commentary…look forward to seeing you tomorrow.
and even if Harbor 20’s all go about the same speed, at least we will be better sailors while sailing on all sorts of boats, if we understand the principles that make our own boat sails its best!
