Port Starboard Bear Off

Robert, You are talking like an A cat sailor. When you let the main out on an RC27, everybody doesn't fall in the water. The boat just slows down quickly. The crew is the most likely person to see the potential problem first and therefore is prepared for a quick bear-off if necessary. My advice appl...

Junk Sails, Obsolete Sails

Hi Eric, The downwind sails that came with your boat are several years old. They were a few years old when your boat was brand new. The technology in spinnaker sails has been moving rapidly over the last five years. A two year old sail is not competitive with a new sail today. This is why the spinna...

ARC21 Spinnaker

Eric, Iwould suggest you get rid of the junk and get a latest technology spinnaker made for your boat. The class with the most spinnaker development in it is the Tornado class, Ullman Sails in the US. I would suggest you get a spinnaker made to fit your boat, your luff, leech and foot measurements, ...

A Sailing 101 Lesson

Hi Guys, This lesson has nothing to do with the above situation but the situation does remind me of something not many sailors know. >>> When sailing to windward and you have to bear off instantly, the boat will do so only if you dump the mainsheet and take all the load off the rudders at the same t...

Rig Tight?

Peter, Since your boat has shroud levers, there is an easy for me to tell you how tight to set your rig. When you are closing the last shroud lever, you should be taking all of the slack out of the rig as the shroud lever handle approaches level, horrizontal. As you close the shroud lever from 3:00 ...

Mast Rotation

Peter, The reason for low shroud tension in light air is because as the mast rotates it runs into the leeward shroud. If this shroud is tight, it will stop the mast from rotating to the proper position. If the leeward shroud is slack, the mast is free push the shroud out of the way and rotate to the...

Boat Overload

Hello Grins, There is one very important and overlooked factor about taking extra heavy loads, extra passangers, out sailing on a beach cat. There is no problem taking large numbers of people sailing at the same time in light winds. No overload possible. The problem comes on a windy day. On a windy ...

Hi Tom, There is something you should consider. The boat is designed for two persons on the trapeze, max righting moment, with a safety factor of a little over two. That max crew righting moment would be something like: Ri Mo = 2 x (8ft+3ft) x 160 lbs = 3520 ft lbs. When you add another person stand...

Sail Cuts

Hi Wouter, I mean Mike, In the beginning of the vertical cut sail trend, there were many iterrations between sail cut, sailcloth construction, the use of computers to design sails and computer software. "The change, the new style," to the vertical cut sail got so much attention that sailcl...

Panelled Sails

Hey Guys, On Catsailor there is a thread about the Tornado class and some sailors at today's Olympics have shown up with "panelled" or cross cut sails rather than tri radial or vertical cut sails. These new panelled sail cuts are thought to be faster than the old tri radial cuts. Also new ...

New Boats and Prices

Hi Guys, I just read about the new Eagle 20, a 20ft boat and all carbon. It cost 32K at the factory in Germany. The boat won the Texel Race this year beating a Tornado by two minutes out of a 2hr and 41 minute race ET. If you add to that base boat price some freight to get the boat to the US and som...

Crew Weight Correstions to PNs

Hi Glenn, The ARC22 does not have a roller furling jib because sailing to windward with a furled jib is slow. A furled jib makes drag just like another piece of mast section 32 feet long going along for the ride along the jib luff. Been there, done that; it doesn't work. You and Steve need to learn ...

Halyard Lock

Hi Dan, You can get any part you need for a SC or ARC boat "from the factory". The halyard lock at the top of the mast is not all that big of a deal. On boats where the mast is structurally marginal, the extra compression coming down the mast due to halyard tension can be eliminated with a...

ARC22 PN????

Hi Thom, The PN system is emperical. That means it is based on data, race results, elapsed times relative to other boats to be exact. US Sailing/Darline Hobock has received race results, elapsed time data, that say the ARC22's PN should come down to 57 to be more fair to the other boats. I guess the...

Great Bay Race

Hi Guys, It sounds like you all had a real blow out at the Great Bay Race. There is one thing I don't understand. Why does an 8.5ft wide boat beat a 12ft wide boat in righting moment limited conditions. I also noticed that some H20s beat the 22s on corrected time. What's going on??? It seems like yo...
