The mast-butt position is a critical speed factor. In general the pole end clew should be kept slightly lower than the leeward clew. With no backstay tension there should be 2.25 inches of pre-bend. Pay special attention to the battens and batten pockets for wear and tear. LEAST … The trimmer often sits to leeward and sticks their head out once in a while, but the tactician will normally be the first person to look around to help the skipper place the boat where needed. J/24's main features Stock genoa tracks should have two new car holes drilled between each factory hole, allowing you to adjust the genoa lead in half-hole increments. This is when you most need to be mindful of the boom, as the boom will swing from one side of the boat to the other when you tack (you don’t want to be in its way when it does that.) As wind and sea state build, start moving the crew aft, keeping always to the edges except for the tactician, who stands on the cabin sole. The average age of a J/24 owner is late 30s. The biggest thing that slows you down is if the trimmer doesn’t release the genoa sheet soon enough and you “smoke” the back of your sail (against the windward spreader and shroud). Now you can tighten your uppers to 20 on the scale of a Model B Loos gauge and leave the lowers slack. Spreader Angle/Deflection: First cut the spreader length to minimum allowed by class rules, 760mm. Exact location varies with crew weight, but typically the bow is in front of the mast, either to leeward or to weather as needed. Grinding down highs in the gelcoat is not allowed. As a special consideration, try to carry a tighter sheeting angle when you’re off a start line, especially if there is a yacht to … A gennaker is used when sailing downwind as it's a cross between a genoa and a spinnaker (big colored sails). I do my best to take advantage of wind angles where it might shift … Halyard tension affects the draft position of the sail. It helps stabilize the boat, and you can trim it like a staysail when planing. Once the crew is all hiking, the traveler slowly goes down until the car is centered as the boat becomes overpowered. The other reason tuning (here we mean rig tuning) is important with the J/24 is that we are asking a very limited sail inventory to perform over a very wide range of conditions. The skipper sits forward of the traveler, to windward, for best visibility. We seem to drop a lot of speed tacking. J Hou, Y Sun, L Pan, Z Huang, J Wu, Z. Q. Zhang, A Pilot Study of Individual Muscle Force Prediction during Elbow Flexion and Extension in the Neurorehabilitation Field, Sensors , Volume 16, Issue 12, 2016 . The latest “thru-bar” types ensure the most accurate setting for the longest period of time to maintain the 160-165 mm setting, and any mast can be retrofitted to this type of spreader bracket. Simple question, but are they talking about the angle between the headings on each tack or the angle between the course made good (i.e. Trim to within 2” of the spreader, but if it’s windy enough that you are vang sheeting and still heeling over in the puffs, ease the genoa sheet—you might be easing it out a foot in the puffs, then trimming it back in. It was a lot more of a case of picking a side and being relatively committed to it, given the slow tacking in a J24. A simpler boat also makes it easier to teach new crew members their jobs. I thought a lot less about the tactics of sailing -- where my sails ought to be for the given sail angle -- because I was comfortable with that from eSail. The J24 can turn on a dime. With this shroud tension the lowers have pulled out nearly all the pre-bend, creating a very stiff mast that can be bent by the backstay to flatten the main. Tacking: Tacking is when you turn the bow of the boat through the wind so that the wind switches from one side of the boat to the other. Normal procedure is for teams to drop the genoa between races and hoist again with 4 or 5 minutes to go. Main Menu. Through proper care and maintenance your sails will give you the performance you have come to expect from a North sail. When fairing the keel to minimum thickness it should also be moved forward by removing material from the trailing edge and building up the leading edge.
