The 20' flat water cruiser is glassed & filled, weight is around 13 kg, stiffness is good, it took heaps of carbon uni to do this because the board is quite thin.

Have you ever seen a bow like this yet? Built to maximise fast straight line paddling.

Tomorrow before I sand it, I will take it for a quick paddle to detimine if it actualy works...if not I will sand it off.

Funky.

Interested to hear how that goes. You might find it 'catches' a bit on small chop - but you'd know much more about hydro-dynamics than me.

Nice Dean.. Is that fin-like nose like that to keep it going straight while the nose raises and lowers with the paddling strokes?

Even if it works it looks odd and will make u turns near impossible.. IMO..

DJ

U turns with the 20' board will be done by the standard method, steping back & sweeping the paddle......the only difference with this board... it will be a many steps back

This is the sort of water I am looking forward to gliding through.

i realy love your passion, but with all practality can any of these craft ride a wave bigger than a2 footer with more success than a long board even.i am a surfer my whole life won many various surfing titles and completly love sup. Mind you i ride sup only when small and offshore conditions. I find sup the most enjoyanle way of surfing in such conditions. Swell picks up sup just can not compete with other boards. You know what i mean, no matter how hard i paddle off the top and swing the big friggin rig around its just not the same as burring the rail an gaining speed to come flyimg off the white water.But i love my ocean sweeping big rig much to all my short boarding matesdisgust, yeah they say some **** but fact is they have no back ground and most are average in all forms of surfing. All i really want to say, which were all said in my wedding vowels.If the waves are pumping,i will be surfing.If the wind is howling, i will be kitesurfing,by some chance no wind and no waves, i will be fishing.So far all good! Beats being a dead **** hanging in a pub! Tonights sermon brought to you by matt!!!!!!!!! Sup, kite , fish , walk the dog and be a great husband

I tried the 20' board this morning, epoxy/qcell filler rough & unsanded, dags all over the thing.The aim of the trial was to see if the nose fin worked.
It works so well the tail fin can be reduced to almost nothing, further reducing drag.
The board even paddled into a 10knt head wind with no tail fin at all, the board yawed slightly at the tail, the nose fin kept the board tracking to where it was pointed.
In it's rough state the speed was faster than my 14' board.
Stability was so good, for flat water I could go 24" wide...just to make it interesting.
Turning circle (with no deck grip) was its length. With grip...maybe half that.
When sanded I will get a better idea of speed, .....it should be a tad quicker.
The most noticable thing was that less energy was required to keep the boat going at a top end speed, & far less side changes....all good for racing.





Bottom roughness

The unsanded nose fin

The 2 fins used, 11" & 7"


Hey "onstrings".....or ondrugs...whatever.....the board surfed like a log....when droping down the face....it just kept going!....straight into the bottom every time?...... it surfs like a 20' board with no rocker & a fin on the nose!
If you want to surf a sup try something like this....................8'2"x30" & 5kg

LSD-absolutely stoked that you're out there doing stuff like this and sharing it here-more power to you!

Look forward to seeing the finished product.

Looking good Dean.

You should have been up here yesterday.. We had a honking 40 Knots behind us for our down-winder.. You would have loved it.

That should be your next board.. A real down-winder board.. ..and make it a 14'er so we can compare with my Naish, Jonathans Pene and Olivers Stonker.

DJ

I'll catch up with you one day soon and we'll talk about designs..

In the meantime check out the F14's.. They seem to be the ants-pants right now.. untill the new Naish 14' Glide is released..

DJ

LSD that looks like a real weapon that board just sitting there on the water

and very interesting the whole idea with the nose fin/keel thingy...lol....

he who dies with the most toys wins

rock on

hi, how much rocker is the board if any?
cheers

No rocker, flat is fast for flat water, also it should stabilise the vertical motion a bit when paddling hard.
The nose needs to be in the water for the fin to work & provide maximum directional stability. The 20' board with my weight of 80kg on only draws about 45 mm, having any rocker would reduce the depth of the bow in the water.
I had not planed to have a "fin" under the nose, I thought the very fine nose may act as a fin. I looked at the excess glass hanging when the top was glassed & thought it could be used for advantage.

yeah, didn't think so by the photos. so as i see it, you have entry shape with the "fin' and exit taper. we probaby will see more flatwater boards like this i reckon. i have had the chance to paddle few new custom shapes lately( no a good thing to do really, they make mine look slow), but this looks really quick and effortless. i think there would be a lot of people drooling to have a paddle on that board.
cheers

Hi LSD as far as bay downwind weapons I've got a feeling that something like this Joe Blair 12'6 could really work, have a read of this review and lots of detailed pics. Interesting that Joe seems to have similar thoughts to Mark R with the F16 - single concave, very flat tail rocker

Lacey I know what you mean but I think it works more like a trolley, imagine a full supermarket trolley - really hard to change direction from the push handle but relatively easy to swing the nose around from the front of the trolley. I think its all about leverage, something in the water 14' behind the tail is really going to have to work hard compared something on the nose "steering" or keeping it straight. Just my theory though!

Hi LSD,

looking at your pics (especialy the one with the paddle on the deck) it shows a very fine front, progressivly getting wider past the mid point, near the tail and then reducing in width at the back.......just thinking about cars planes etc especialy those built for speed, most have a larger frontal area with reduced tails.....makes for better COD....would this work at all on a paddle board??? so basicly turn the board around, build the nose fin into the back and mount rear fin up front....make any sense?
