BelSkorpio Hi Unregistered,

1) I've compared a 85 wide Fanatic Falcon with the US 2011 in combination with a 9.3 sail. The 85 Falcon feels lighter and has more top end speed, at least for me. The US planes earlier and much better through lulls and also points better. I've tried both boards in exactly the same conditions on the same day and with the same sail. Believe me, the difference is quite substantial and it becomes even bigger when your body weight goes up. According to me, in light conditions (10-15 knots) with typically a lot of lulls, the US would win each time a Slalom 8 race. In 12-17 knots the difference would get smaller. If you purely go for the thrill of max top end speed, choose a 85 wide board.

2) A 10.9 works great on the US, but with a bigger fin. Some say 62. I have a 64. Perfect. What do I gain c/w a 9.3 sail ? about 2 knots. That's all. But it's a lot in the ultra light. It can mean the difference between planing or not planing. I plane from 8 knots without too much pumping and maintain planing until 6-7 knots. This is hardly possible or very difficult with a 9.3 sail. It would need an incredible amount of pumping, which I don't like. Even more important is the increased pointing capabilities with the 10.9 sail. I don't like to struggle to return to my beginning point.

3) When I said that the US is better pointing than an 85 wide board, there is even a bigger pointing difference between the US and my former Formula 161 (70 fin) in combination with a 10.9 sail. The Formula is unbeatable on that level. On the other hand, the US feels much lighter and has far more top end speed fun (for me).

US 147 with 10.9

Hallo guys, I read this quite old topic, where I see some of us tried the Ultrasonic with 10.9 sails.

So, I am quite interested on buying an US (or equivalent; today best option is the US), so I have few questions.

First of all, I am 75 Kg, height 1.75m, having 9.5 race sail and 85 Manta slalom, I have big experience of FW racing, never had the opportunity to sail the US or equivalent.

So, the questions are:

1) I suppose using an US with 9.5 is not a big inprovement to the Manta 85 (or equivalent) and same sail; what do You think about?

2) If You confirm me the 10.9 is well suited and confortable for US, do we have an inprovement vs the 85 and 9.5?

3) what about the comparison beteween the US+10.9 vs FW?

Please note I disagree on the fact I read the 9.5 for slalom is more powerfull of a 10.9 for FW.

FWs sails are designed for big and heavy boards, moving at very slow speed (comparend to slalom) and different angles, while 9.5 for SL are designed to very high (in comparison) speeds and different apparent Wind angles. So, to me, an FW sail well designed has always more power compared to a slalom one.

Thanks
Giuseppe

mcross19 Without trying the two back to back I couldn't say but they seem the same upwind, just need to be planning and a decent size fin.

BelSkorpio YES. I Completely agree.
I wrote this already more than a year ago in a thread. Don't remember anymore which one.
I cannot compare with the 2013 version of the US because I've never tried it but I compare with my former Formula 161. Perhaps I shouldn't compare with a Formula because obviously the US is NOT a Formula but I also found that pointing was not the best property of the US.
What I can tell you is that a bigger fin (e.g. 64) in combination with a 10.9 sail and the mast foot way back helps A LOT. So, indeed the US needs power for pointing. It handles the power also very well and that's why I like it a lot.

Interesting to hear that the 2013 version points better. Must be the wider tail, although I haven't checked the specs.

Getting onto the plane with it, yes. But pointing upwind, doubtful.
For me I found the 2011/2012 Ultrasonic pretty poor upwind unless well powered, where the 2013 seems to easily fly upwind, even when not fully powered(using the same fin of course)

I probably plane as early with my 8.8 & 58 fin as with my 10.9 & 64 fin in marginal conditions, but then often after 1 rack + a jibe, I need to slog back to the point where I started off. Something that I hate.
In PWA slalom races, they don't have this problem too much because they go slightly downwind all the time.

On the other hand, I you take a sail that has a lot of low-end power (typically a light wind 2-cambered free race sail) you can quickly get overpowered when suddenly the wind picks up. I had this often with my 9.5 freerace sail which I sold because of this reason.

mcross19 That was an interesting point about the 9.6m being as powerful as a formula 10.7 because this is the discussion I had with the guys at Point 7 so they have made me a 10m Custom AC1 Slalom sail which I will use on my Ultrasonic. It weighs much less than a 10.7m Formula sail due to a shorter mast and boom but it is supposed to be equally as powerful, be interersting to get it going on the water.

The one big improvement the 2013 Ultrasonic has it the rear foot strap position has been moved futher outboard giving you a much more comfy stance on the board when planning.

mark h [QUOTE=Maybe one day the PWA will see sense and allow these 90cm+ wide slalom boards in competition. Far less cancelled heats and sitting on the beach as they push the wind minimums lower, which can't be bad for the sponsors[/QUOTE]

Good point. the extra 5cm could mean a lot more heats would get done, especially at some of the events known for light/flukey conditions. Must be gut wrenching for the pro's to sat on the beach during an event.

Could mean a whole new generation of fast 90cm slalom boards. I remember how quickly Formula developed/improved in its early days.

the RS7 is a board i hear little about and cannot find it listed in US not Canada
glad you have shared info on it !!!!!
No experience with the SLW92, I have read that it can be pretty fast in the right conditions. Since its positioned more towards the intermediate sailor by JP with an outline a bit like a formula, it was not what I was looking for in a super lightwind slalom board.
