The 18HT of course I single hand my 18HT up to 4 Bft. But I'm sure that you can trapeze earlier on the A-Cat than on the F16 (plattform is wider and has a shorter mast) copyright pictures: http://www.ehlers-media.com/

I'm not really sure actually. That is when limiting the comparison to F16 and A-cats. I know for certain that on the downwind legs the F16 will have you trapezing first under spinnaker; as a matter of fact you hardly ever do the wildthing on the F16's, there is always enough power to keep you on the luff hull. Of course when the winds are too light to fill the spi properly then no catamaran will pull 97 kg on the trapeze on downwind legs. On the upwind however I'm not too sure which of the two will put a man on the wire first (when singlehanding). The A-cat has a taller mast 9 mtr compared to 8.5 mtr but then again the F16 has more sailarea 15 sq. mtr. to 13.7 sq. mtr. These two aspect seem to balance one another quite well. Of course the A-cat is both lighter and narrower as well so maybe the A-cat goes to the trapeze sooner on the upwind legs. Having said this, the F16 comes standard with a double hander mainsail that can be trimmed for singlehanding by making it flatter. So in effect the standard F16 mainsails are cut to pull 120-150 kg on the wire in about 10 knots of wind. This means that a singlehander will be pulled to the trapeze alot sooner, even when the guy is 97 kg's. On the other hand both classes allow the owner to order a mainsail to suit his weight and style of sailing so in effect each boat can be made to pull a 97 kg sailor to the wire at exactly the same moment. So can do this even at quite low windspeeds even, when you are willing to accept that in the stronger winds you'll get hit more. So I guess it all dependents on what kind of hardware you fly on either boat. I personally use my doublehander mainsail, cut for 150 kg combined crew weight, both for singlehanded sailing and racing. I notice that I need to depower it pretty soon; I'm 85 kg. Up till now I haven't been able to see on the water when the A-cat could fly and I couldn't. Most often there was too much wind and we were both out; in addition the sailor on the A-cat in my club races is not really of the same sailing skills and he is considerably behind me in the races. Not his fault however. I'm 33 and he is 76 years of age. I have alot of respect that he is still sailing cats at that age. In other races where I shared the same course with A's of skill I was double handing. Wouter

Posts: 1,382 Essex, UK | Rolf, The only time I've come up against an A in marginal trapezing conditions, it was a 5-6 yr old Unicorn. Wind was about 5 - 8 knots and with the F16 I was out on the trapeze much more than the guy on the A. I'm just over 10 stone and I would guess that the A sailor was over 11 stone but about my height (5' 10"). Don't know if this really helps though..........

A unicorn is quite a bit underpowered compared to a modern A-cat. I think they only have 12 sq.mtr of sailarea and a 8 mtr tall mast. Not too sure wether they are a good approximation.

Maybe I can simplify this for you.
1. If you want the highest quality class racing, no question the A-class is the choice. Other than the Tornado class, you will not see as much depth in any other class. At our 42 boat US Midwinter race week, there were four Olympians (three were medalists), 3 world champions, at least 8 sailors who had won national or North American titles, and then a bunch who have consistently finished in the top echelon of various class championships. The racing is not boring at all! 2. The F-16 is a great package. As a two man sloop, I believe it has the potential with the right sailors to be faster than the F18 except in light air (the F18 pays a big penalty with its weight if the crew is not on the wire). Once the F-16 is powered up, it rolls. The A-cat is always faster upwind but is not as fast downwind in over 6-7 knots. Even though it is lighter, it cannot keep back over twice the sail area the F-18's and F-16's have at hand. If you want a boat that you can race with 1 or 2 persons and really want a spinnaker, the F-16 is probably the better choice for you. 3. An A-cat is as durable as an F-18 or F-16. The boat does not have to built as heavy because the loads are lighter due to the rig and it is designed for singlehanding. I've owned three boats and they were all excellent. You should get easily a minimum 5-7 year competitive life from your investment. 4. The A-class does not want spinnakers for class racing. The racing itself is very tactical without them and the class loves the simplicity. Jennifer Lindsey (an excellent F-16 sailor) got an A-cat because of that simplicity. Yes, spinnaker boats are great (I've sailed many) but I've never found the A-cat boring at all. You really have to put the time in the A-cat to be fast downwind and I love the challenge of refining my downwind technique in the boat. I've toyed with the idea of a spinnaker for my A-cat but am quite happy leaving the boat the way it is. I'd rather have the quick setup and rigging time and focus on refining my boatspeed for class racing which I enjoy the most.
Hope this viewpoint helps.

Posts: 1,226 Atlanta | Wouter The quite a few of the HT's went with the double forestays and didnt have a problem gybing the kite. Generally the pole is out in front of the bows and the forestays are attached a ways back on the bows, so I dont see how it will be an issue on an 18ft boat - A cat, HT, etc.
It might be an issue on an F16 because you have less bow, perhaps, but on an 18ft boat you wont have a problem. Keep the pole long and the luff long and you wont have to worry about the forestays interfering with the sheeting angle.
As far as keeping the pole supported, I think you could use sticks and mount them over the forestay eyes and make it removeable. This would support the pole and keep it in place without drilling holes in your bows. The other issue is on a modern A cat, the bows dont come to a point (XJ, A2, etc), so there is no perfect mounting spot, so I would move it back to the forestay eyes.

I went F16 for the versatility. My situation was/is: inland lake sailing most of the time (light air/flat water), buoy racing most of the time, no consistent crew on N5.5SL and young kids getting to the age where they'd enjoy sailing (ages 6 and 8). I was looking for these characteristics in a boat (in no particular order): 1. Lightweight, I need to be able to handle the boat by myself (8 year olds aren't that much help) in the water and out of the water (I weigh 155 lbs dripping wet) 2. Able to single-hand easily (even if racing in an F16 fleet). I'd give up 18 inches in mast height to N5.5 Unis from my N5.5 SL-to-Uni set up. 3. Good light air boat, see local conditions above (no class min weight either). 4. Fast out of the box, I don't have a ton of time to tinker (I'd like to but....) 5. Integrated class legal spinnaker 6. Ability to be "Competitive" at coastal regattas/distance racing from time to time. "Competitive" meaning the boat is potentially quick. Crew ultimately decides "competitive". 7. Production built, my wife wouldn't let me take "her" children on any boat I built. 8. Racing centric atmosphere. I enjoy the post race breakdown/bragging sessions as much as the racing. Being with like minded people is fun. I had a tough time deciding between the Blade F16 and the Stealth F16. Both seem to be awesome boats, but the Blade has a "local" manufacturing presence lending to an assumption that it will proliferate quicker in the US (can you say Alter Cup boat in '07). Theoretically, parts will be easier to get, etc. I still may try the Stealth rudder system on the Blade . That about sums it up. Thoughts?

Posts: 3,348 | Tom: I've decided on the Blade, just waiting to hear back from Vectorworks. The versatitility was the biggest factor. The absolute final point in the decision process was the video, on the F-16 site, of the Blade being sailed solo! The slightly lower cost was also a factor. That difference will go a long way in experimenting with sails! I will still, almost certainly, buy an A cat. Just, not this time around. Robi: Thanks for the offer. Hopefully, by the time we set it up, you can give me some rigging tips! Anyone know how long it takes to get delivery?
