Posts: 1,669 Melbourne, Australia | Someone mentioned that you loose your warranty when adding a spi to an A-cat. I haven't seen that note on any A-cat builder site! Actually I haven't seen ANY kind of rules for what you can or can't do with your A-cat and still have a valid warranty. Please check facts before stating such a thing!
Hi Mate, As far as Autralian High Performance Catamarans are concerned (builders of the Auscat Flyer and Boyer boats) they have a very clear warranty for all their boats wich you can find on their website. A Class warranty link | | | Re: No warranty when adding a spi to an A-cat?

By the way, I have only sailed the A-Class this one season, but I don't think adding a spinnaker to this boat makes it better! It makes it heavier and more complicated. In light air, it makes it quicker. I am not sure it gets quicker with spinnaker once you can wild thing. The thing that makes my A2 my DREAM BOAT is that it is extremely simple to assemble, move around, and sail. I don't claim it is simple to sail well, just that you can sail it easily and simply. The next part of this being my DREAM BOAT is that I find that it responds to changes in adjustments of the outhaul, downhaul, mast rotation, mainsheet tension and traveller position. I have a lot to learn, and that fact makes my A2 my DREAM BOAT...plus it goes upwind like nothin' else!

Take him up, with 350 square meters of sailarea creating a very personal and nasty vacum for you to the lee?? I would very much like to see you yell "up-up-up" to them as you try it The 60 footers are incredibly fast even in light winds, I think Groupama 3 will be even faster. | | | Re: No warranty when adding a spi to an A-cat?

I guess that's what you would have done sharing the line with such a monster. We have shared the starting area with some 60 foot tri's, and kept well away from them! They are _fast_ and _very large_ | | | Re: No warranty when adding a spi to an A-cat?

You gain about 30% of downwind VMG in higher winds if you compare an A-cat+spi with a normal A-cat. In lower winds the gain is a bit more. Upwind you loose a bit, 5% maybe? How much you loose depends on the type of snuffer you are using and if you're using external or internal halyard for the spi. The "gain factor" between upwind and downwind is approx 2, that means if you gain 5% of downwindspeed with some extra gizmos and loose 2.5% upwind due to the gizmos you haven't gained anything during a complete lap. You start to trapeze downwind in about 8 knots of wind, and in 18 knots of wind you must stand with the rear foot close to the rudder to keep the bow up. Use a chicken line or footstraps to stay attached to the boat. I have several plots of downwind sailing with the A-class using the spi and in 16-18 knots of wind you are doing around 17-19 knots of boatspeed with an angle of 30° to a direct downwind course (15 knots VMG). If you go wild thing without spi you will sail around 45° angle to a direct downwind course and the speed would be around 14-16 knots (11 knots VMG). The course, one lap plotted: /håkan | | | Re: No warranty when adding a spi to an A-cat?

Posts: 953 Western Australia | Wellllll.. I think for safety they would start the fastest boats first.. Cutting one way thru a fleet of a hundred dead slow boats wouldnt be nice.. (Although lifting a hull above the mast tip of a maxi would be fun ) Add to the congestion issue is the spectator fleet.. Maybe a few thousand of various sizes and abilities (and when talking about abilities I mean the skippers with the booze content approaching 0.1%).. Starting the big cats/tris a km or two down or upwind would be the best option.. But the spectator fleet is a huge issue and Groupma3 being cut in half by a drunk on his 75 foot palace isnt worth thinking about!!.. S.. | | | Re: Dream Boat?

How could we forget the M26 in a thread about dream boats. You should realy go see the guys at Sailing Anarchy. They are avid Mac 26 fans. | | |
