Out line only rough shaped so far.
I will probably pull the fat arse in a bit yet. I'm not that keen on that.
The aim is to promote as fine an entry for the displacement bow as possible with the wide point aft.
Tail......displacement or plainning? What do think?
width will end up around 28"

hi,dale had a 14' wrong profiled blank we cut down to 12'6. not a radical as yours, but similar. displacement concave nose to flat to double concave with a fair amount of tail volume. goes well- paddles fast, surfs pretty good. haven't done a d/w yet, but was catching runners in the creek with a ne wind and swell without to much trouble for a 12'6. its what i would call an all round board travis won the supsa race and he is going to race it on sunday at coffs
cheers
ps if you keep the tail shape and volume, you may need a bit more nose rocker than normal, i sure you are probbably aware of that

The front part looks great but I'm not so sure about the back part. Let us know how she goes...

i'm wondering what usage you have planned for the board
cheers

Looks like the small hand on a big clock.

It looks great. Just put the fin in the pin end turn it into a pin tail with a rounded nose for easy entry, early planing. [}:)]

Once it reaches production, it's way past beat you 2 it!

Will be riding the 7'9" tomorrow at the SPSC event. (maybe conditions permitting)

Hi Dean,

As far as the "nose fin" idea on the 12'6 goes, depends on what you want to do. In open water down-wind conditions you are constantly doing small adjustments to your direction to catch swell from different directions (usually there is a wind swell and the ground swell). Even when you are on a wave you keep your eyes open for some swell coming from a slightly different direction that you can pick up to keep the glide going, with a rudder when you are not in surfing stance you simply steer into the next little trough. A nose fin would stop the ability to do that (or at least make it harder), the thing to get your head around is that in lighter wind/choppy conditions you could be making these subtle direction changes every few seconds.

Look at Jeremy Riggs and the water state, when you paddle with Jeremy he is constantly changing directions and trimming and most of the time gliding on those small faces. He is on a Foote Maliko 14 that is 25 wide






Very different in up-wind or cross wind paddling where the nose fin could be a great help, now if it could be made retractable by kicking a lever or pulling a cord I can see some huge benefit. It would only take a second to bend down to cleat a line in the same way the kayak rudders retract or have a mini windsurfing type pivoting centreboard case in the nose with a lever running back that you could push or pull with your foot. Actually that's a pretty exciting concept to try out!

Just some more input to digest in the search for the perfect craft....

Hey DJ.....why can't I put a nose fin on my 12'6"? Whats your ideas here? Asthetics?
Starboard are obviously trying to minimise yaw & maximise stability with that Interesting shape fin....max area aft & deep....my new board is having a similar shape...a little more swept back.
Well talking asthetics? What's your opinion of the pointy spa bath?

Dean.. Check out this link showing the new displacement hull F-14.. It may give you even more ideas.

www.standuppaddlesurf.net/nggallery/post/s-i-c-fw-14-displacement-hull-stand-up-paddle-sup-race-board/slideshow/

My thoughts about no nose fin is not about aesthetics.. I think the nose fin looks great.. works great.. and is very cool.

I'm thinking a board needs to be a planning hull or a displacement hull and mixing the two will be very tricky.. but it may also work.. I'm no expert on all this.

I like the idea of a displacement nose for non planning conditions and to help raise the nose when pearling.. and I like the idea of planning rear section so you can get more speed and surf ability.. but once surfing on the tail if that non planing nose touches down it might bog down more than a planning nose like a concave nose.

I'm thinking if you want to keep the nose area out of the water when planning you don't want a nose fin catching and bringing it back down.. and a nose fin will also reduce the surf ability (if it touches).. and also reduce the turning ability when flat water racing around a course.

It will be interesting to see what you come up with.

DJ

So many things to take into account when shaping. I guess like all boards for all sports it will have to be a compromise unless you want a 10 board quiver( This may be Jonathans aim)

Brendan, How do we determine what is flat bottom in a 12'6 class?

Sprung

I'm not sure about the flat bottom 12'6 thing either - figured Brendan just made it up so I couldn't enter The Pin in the RPS event.......

Don't think I've heard of it before as a class.

Funny thing with the rocker on The Pin, I'm actually getting used to it for down-winders. It doesn't feel as "right" straight away as the 14' Glide did to me in strong wind but it seems to be really good when the wind is a little lighter, maybe because the displacement front doesn't plow like the flat bottom boards do so it's a little easier to coax onto the smaller waves. Incredibly versatile board, swapped back onto my old regular 12'6 Starboard mid down-winder the other day and couldn't believe how much slower it felt in those less than 20 knot conditions we were paddling in.

So... go the quiver!

Cheers Johnathan,
I've had the pin out a few times but not in strong wind or chop. Hopefully I can get some practice in those conditions before next month.
Look forward to meeting you in January.

wow those starboard shapes are nuts

cant wait to check one out in the flesh

anyone know much about them????????

Not my idea, I just saw other people doing it in events, I think the 12' flat bottom was the rules for
the last Sydney event (at Manly maybe?).

I really like the idea so SUP doesn't become an equipment race like sailboarding did back in the 90's.
I was a part of it and to me this was one of the reasons sailboard slalomand course races became
non existent.

As far as determining a flat bottom, I think the board would need to have a flat bottom no less than
2ft back from the nose and continue through to the tail. BUT to be honest I have no idea, just a guess!

Instead of a nose fin perhaps a set of FCS plugs forward of middle to help with straight line paddling in certain conditions and can be removed when not required.

I like these boards from Tahoe california

tahoesup.com/

They have the centre fin and it works great

Hey Dean,

That board is more like a Stand Up Canoe! Makes me wonder where it will all end up!

Short Board Sup
Longboard Sup
Flat Water Sup
Down Wind Sup
Ocean Going Sup
Stand Up Canoe
Side Walk Sup
Rip Stick Sup
Thats about a $15 - 20k Quiver how many boards does a Supper need lol

Thanks for that link DJ.....very interesting....some seriously fast boards in that range & looks like they have most conditions well covered.
12'6 x 231/2" ....thats getting down in width!
........& a 14' with a center fin!...maybe they are softening up the public for nose fins on flat water boards?

And the windage.....particularly in cross winds?
