After 5 years of paddling you would think he'd work it out!
DJ trying the 20' board
id still like to see how it goes backwards, obviously the fin would need to be sorted.
just thinking about all the streamliner cars, and aircraft etc.....COD

Nice one LSD, that second vid looks like its moving very quick with little effort.
Thanks Dean.. That 20' board of yours is absolutely awesome to paddle.. So.. soooooo so fast it's incredible.. also so stable for a narrow board.
It slips through the water without a sound and there is almost no load on the paddle because it slides along so effortlessly... Amazing.. 
That nose fin is perfect.. Any yawing on a board that long would cause so much drag.. and the nose fin keeps it going as straight as an arrow.
DJ
LSD and DJ ,that nose fin . I can't think of any craft I've ever seen having one of those. Not criticising but is there a good reason for it. I can't think that it would yaw at all at that length . What about cutting the nose fin off and putting a fin box in , so you could fine tune the size and shape of the nose fin .
Logman.. I was not sure about the nose-fin at first but I now think it's a great idea.
I'm sure a fin box on the nose would also work but I like the super smooth entry of glassed on fin...btw I think it would yaw some without it.

DJ , I'm not much into the racing side of SUP but that thing looks so graceful on the water . I recon a 5 kilometer paddle on early morning glass aboard that thing would be the ultimate stress reliever . The only problem as I see it would be the garfish . I pity the poor little buggers , swimming on the surface , minding their own business when suddenly they're filleted by that mother ****er nose fin. Maybe if LSD ever sells this one it should come with a nice beer batter recipe
Hi LSD and DJ , I'm still not sure of the science behind the front fin . Do you mean ,by assimetrical power source that a C1 paddler wouldn't face the same problems as the your boat . I've never seen a front fin on a C1 ( I have been wrong before!!!) . Here's a plan, get that thing sanded, nice and shiny then make a mold of it . I recon half the people on this site would love one . Maybe you could have your own class like " Hobie " or " Mirror" . We could even have bay races in our new " Formula LSD's".
Looks fantastic LSD, well done and thanks for the video footage.
Logman, you should consider some of the recent America's Cup class designs - where the rudder foils have been added in front of the keel - in some designs there are two keels at either end of the boat. Considering these are the fastest sailing boats in the world and the greatest amount of R&D behind, LSD is onto something here. The long water line would be the difference with a C1. Like you I'm no hull expert, but this is an amazing experiment to be able to witness from birth to actuality.
DJ - can you elaborate more on the speed you felt? Was it significant?
Cheers

PS - did you really put the board on the water upside down or was that a joke?
LSD was it you who said in an earlier thread that you could pump these things out for a few hundred bucks each? About $250 if I recall correctly?
If so are you taking orders? I'd happily pay over that too. There is a definite need for sub-$1000 SUPs of reasonable quality. Respect to the big brands for all the R&D they do and developing the sport but the pricing is out of control and makes it very difficult for me to recommend the sport to anyone who isnt Scrooge McDuck. Especially if they're not a hard core surfer or waterperson.
I'd be very interested too in purchasing a board.
I found this link about twin keels:

The idea was first floated in the late 1800s
Sailing hydrodynamics are very different to paddling ones, but it is an interesting read and demonstrates that what we expect is not necessarily what is right.
Heres to lateral thinking.

Ya see what I mean LSD !!!!! There gagging for it . I'll be happy with my normal 10% fee . Thank you
I had a paddle on the board yesterday too. I've paddled 16 and 14' boards and own a 14' Penetrator - all designed for open water and wave so with rocker. As far as flat water speed for paddle input this board is in a completely different league.
It's 26" wide but very stable, I'm sure for me at 67kg I could go to 25 or 24" without a real problem.
About the front fin? I'd really like to chop it off and try without it because my gut feel is that it does help the board track very slightly straighter but I think the very fine entry probably does that pretty well anyway. I think I'd rather trade off a little arrow straightness for a little more steering ability.
Front fin or not, the thing is absolutely gobsmackingly good!! Well done Dean and thanks for the chance to try it.
but you get my drift
I thought canards are a smaller fin that's just before the larger fin.
They try and direct the flow in a better direction over the larger fin.. or wing.. Some fighter planes even have them.
I guess even on a plane thay can go way up the front..
DJ
. 
On some aircraft the canard is set to a different angle of attack to the main wing so that the nose stalls before the main wing. It's a safety feature for very manourverable aircraft.
en.wikipedia.org/wiki/Canard(aeronautics)
All this begs the question of why do you need a fin at all on something as long and skinny as the 20' SUP. Presumably in smooth water it's going to be very directionally stable.
Sailboard history is full of silly fin (and sail) ideas that came and went. They lasted one season until the designers worked out how to make fins properly and went back to a properly foiled fin. (Remember fence fins and slotted fins and kanga cocks and cutaway sails?)
Hey dean.. While checking out canard stuff I came across this vid..
It's new Russian jet fighter and you can see the two small canards just in front of the main wind.
Impressive vid.. www.liveleak.com/view?i=b03_1235060325
