Good tip. How do you determine 2 and 4 degrees? Simple trick? Bill Walker Evening Star CnC 36

We do similar on Touche'. I have a 36 inch wheel that is used only for racing. Normally, I use a 32. We use tape, green for TDC, yellow for ~2 degrees, red for ~4. When the main trimmer sees the red tape stripe at the top he eases the traveler. A "visual" boat is easier. We have a Navtec hydraulic backstay. I taped a small batten to the cylinder so it extends upward several inches to the head of the ram. On it are green, yellow, red and black tape marks. We adjust the backstay to the desired headstay sag then remember the color where the head of the ram is. Easier than looking at the pressure gauge. Dennis C.

Some lessons learned. Sail her flat, no more than 18 degrees heel. We have inclinometers on the back head and the helm and trimmers work to keep her in range. Check your sails. If they're old, they're too baggy, you're gonna heel. We have low stretch racings sails. Lowered our weight aloft a lot and they don't let the draft come aft as the wind picks up. Useful tools: hydraulic backstay adjuster, bridge deck mounted traveler with a windward adjustable car, cockpit adjustable genoa cars, powerful cunningham. Tune your rig with the mast raked 10 to 12 inches. You sail a 30-2, with its broad beam carried so far aft, differently than the older designs. We actually steer Septima with the main because the main trimmer has the windward car and is sitting on the side deck in front of the helm where they can communicate easily. Our wheel in marked each side of TDC with a seam that indicates 4 degrees of rudder. Helm puts the appropriate seam TDC, trimmers trim the sails, and, as the boat gathers speed along the course line, helm relays to main trimmer whether helm is light or heavy. Main is retrimmed using the traveler only. Object: keep the foils moving thru the water at 4 degree incidence angle and keep heel 15 to 18 degrees. As wind speed picks up. use sail controls to keep things in balance. More backstay pressure, halyard tension, aft movement of genoa cars as needed for headsail; more cunningham, traveler to leeward, twist off the leach for the main. All these actions keep the boat balanced, fast and stable. I have never had the rudder stall. Its always at 4 degrees incidence. Can help to move crew weight aft as wind really picks up. It's not rocket science. Allen Miles S/V Septima Hampton, VA Oh yes, I was a rocket scientist.

Weather helm yes, it could be a bear. Round ups never. I could bury the rail deep and just keep plowing along. My 30MKII's rudder will stall then round up out of control with to much sail up and not enough tension on the backstay. Too much heel and it gets scary. All that being said im still learning on my MKII _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com CnC-List@cnc-list.com _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com CnC-List@cnc-list.com _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com CnC-List@cnc-list.com
