Lost my cherry...

Agreed, a little too high there.  But cats go best with one hull just out of the water (from talking to 1/2 boat sailors  this is the most difficult thing they find - FLAT is not fast)

Oh, and the fact cats are F...ing hard work !

fast tri's fly two hulls BTW

Capricorn workin it upwind in pressure

Buy a cat, you know you want to....

If sailed right a cat should be powered up in 5 to 8 knots.  That is all crew trapping and flying a hull.  When it is marginal, moving your weight in and out to keep the hull up is what it is about.  Also, use the apparent (upwind) to induce hull flying and as the speed and apparent increases, flatten the sails, point higher and keep the boat moving.  Form 8 to 10 knots you will not have a problem hull flying.  It is then about making best VMG.  Balancing hight with velocity.

In light breeze, it is all about moving weight in and out, just like on a mono.  On the cats as with HP Skiffs, utilising the apparent wind both upwind and down is the key to making the boat go fast.  As I said before, sailing a cat can be quiet easy and may seem less skilled to the uneducated.  That is why cats are so frequently used at resorts....  Can be easy to sail with good stability (if you like sailing on 2 hulls).

I have sailed many Cats, Skiffs and Monos extensively and can say from my experience that neither is less "involving".  Both whilst simular also display suptle differences in techneque to sail.  I believe that apparent wind boats such as cats and skiffs are more "involving" and challenging as speed is even more so critical.  You also not only play the wind shifts but more emphisis is on playing pressure especialy down wind using 'velosity'  lifts and knocks.  Crew work is also even more critical, because mistakes are punished with even more boat lenghts lost the greater the speeds increase.

Just remember that you are turning a lot of boat.  16 foot cat = 32 foot waterline (2 hulls).  Guys that are smooth with the stearing are the quickest.  When tacking, a good roll tack helps greatly.  On cats, you can not jerk the tiller around...  Smooth is the key.  Helm should not be heavy.  May be the rudder rake or sail trim was not quiet right.  Should be able to steer with 2 fingers.  Some cats like the F-18 and Tornado are very sensitive to downhaul.  If you are sailing in to much presure with to little down haul, you will get quiet a bit of weather helm.  Trim right and find the groove and you will have a big smile on your face.

You will find that a lot more muscular effort is needed to sail a cat, particularly in the sail controles such as main sheet and downhaul.  With the cat, you do not have a boom vang (kicker) and the sail is a lot more high aspect.  Whilst you can play the main on a mono or skiff with on arm, a cat you will need two and plenty of leg and sholder.

Also a modern rig cat will require masive amounts of downhaul and regularly run 16:1 or even 18:1 purchase.  Cat main sail shapes are very efficent and very powerfull over a wider wind range.  For example the A Class which would have to have the most efficent rig behind solid wing rigs, can be fully powered up in as little as 5 knots whilst still very managable with the same rig in 25 knots.  The F-18 can be fully powered up in 7 knots and sail to 25 knots.  Tornado with its extra beam, powered up in 8 knots and realy comes alive in 25 to 30.

A cat can be quiet an easy boat to sail, but to race and get the most out of it, you will find it quiet difficult and physicaly demanding.

Hope you have the opportunity to try it again in better conditions and just remember even if you are a die hard dinghy sailor, variety is the spice of life.  Try 2 hull, 3 hulls, yachts, sail boards, kite surfing, land and ice yachts.

It's all good mate
