Code zero spinnaker11/6/2023 You save half an hour over the leg for no penalty to your rating! In your 40 footer you would be able to maintain a 10kt average speed with the J3 but with the JT and Genoa staysail the speed has jumped to 10.8-11kts average. If you aren’t sure that 8 % sounds that much consider the numbers. Performance is 8-10% faster than you would manage under the J3. A Jib Top would be the perfect sail for the 65 mile leg at 95-100 degrees TWA and 18-22kts TWS. In the prevailing wind direction and the breeze in the English Channel is a solid 20kts. It's the Dieppe race and you turn onto the final leg, a reach from Brighton to the finish in Dieppe. In combination with a reefed main the boat is perfectly balanced and much faster than using a smaller headsail and full main ( 20kts TWS sail performance comparison chart). Jib Tops are traditionally flown from the forestay but on boats with a bowsprit it has become popular to fly them on a torsion cable forward of the bow.Ĭombining the Jib Top with a Genoa Staysail increases and pushes the area of the sail plan forward, helping to balance up the helm when the boat is pressed on a reach. In above 22kts this sail combination is incredibly fast. It is sized the same as your largest jib so there is no rating penalty. 1 - The Jib Top (and Genoa Staysail)Ī jib top is a high clewed reaching jib which is much more efficient once the sheets are eased and used between a Code 0 and a jib in over 12kts TWS. As a result there are two great options to turbo-charge your reaching performance and always be able to sail at 100% of targets no matter what the wind angle. Luckily, under IRC the penalty for additional spinnakers is low and there is no penalty for additional jibs as only the largest one is measured. For anyone racing offshore or round the cans regattas like Cowes Week this is a real problem as they are potentially giving away a lot of time on the water. The problem these boats have is that the jibs are not hugely effective off the breeze and their large spinnakers are too deep to sail tight angles resulting in a large range of angles where you are unable to sail at 100% of your boats targets. Downwind they use large spinnakers and also have good performance resulting in a set up which works perfectly for windward leeward racing. The average IRC yacht now has non overlapping headsails which can be inhauled and a medium roach mainsail and can go upwind very effectively in all but the lightest of conditions.
