The most successful racing yacht design house in the last 20 years has had a go at designing an Unlimited (18' x 23") & 14' x 26" board and associated fins. Typically these guys design stuff that is pretty quick although their dominance in the racing yacht design market has been eroded since the founder of the design house, Bruce Farr has largely retired.

Very interesting I have been working a lot of night shifts at the port of Brisbane and watching a lot of ships boats enter the port. Ive seen massive tankers that create very little wake , and then a small craft will go by creating a large wake and waves. A lot of the big ships have those big bulbous noses underneath the water line and they create very little wake = less drag? So I looked into it and it appears that it is designed to cancel out the interaction between the bow wave and the stern wave , creating less drag! Any way I like the design

If they are such an award winning company surely they have a bank balance to match why are they looking for partners to make said boards.
The report even has spelling mistakes. Not so good when looking for an investor

Naval architects don't have a great track record at designing boards from scratch that people want to paddle more than once, much less buy in numbers. Anyone else here ever paddle the Coreban Edge?

Yep there are some great collabos between shapers who race and surf and the boat designers who know about the fine points of hydrodynamics and such, but it seems the winning ones all start with a paddler's intuition and a lot of time on the water, not just some lines on a screen, a bunch of clever simulations and a bit of 3D rendering.

That said, good on them for having a crack, you don't get breakthroughs by doing the same things as everyone else.

funny how it still looks like most of the narrow nose boards available on the market and the fin is an axe shape.

My theory, semi planing nose shapes in both rocker, planshape and underwater section.
Race boards glyde off of their nose sections.
You have to reduce the wave drag at the bow, the easiest way to do this is get the nose to plane.
Really who cares about wake waves all boats / boards create wake waves even when they are planing.
Bow waves are a sign that the board/boat is pushing the water out of the way not parting the water.
Too many things to say

I'm no yacht or board designer, but that board has banished the use of 'turbo' as a model name for a SUP for at least a decade. The only thing they may have got right is that good dogs have a wet, black nose...

The Farr design looks like a Starboard Sprint. So it will probably have the same strengths and weaknesses.

Sure that this shape involve row effect in a towing effect. As well more drive from the paddling, cross wind won't affect the drive.
maximum planning and directional Stability

Wasn't the Turbo designed by a submarine architect? Not my first thought when choosing a race board - how well does it submerge and sink to the bottom?

The Turbo isn't *that* bad. It's pretty fast in flat water, which is what it was designed for. And I was surprised at how well it went upwind in small chop in the sea, and it's even possible to DW it a bit, if you have the skills. So, sure it seems like the designers should have tested some prototypes more thoroughly, and for the money there were better choices. But it wasn't completely without merit as long as you were only gonna use it for a narrow range of activities. All those fins did attract a lot of weed though.

I'd buy a flat water board designed by a boat builder but if you're after a board for downwinders I'd be looking elsewhere.

Well the boat designers that worked for Coreban did a pretty good job with the Dart. In fact I think it was the only board that came out of that design house that I'd personally call a real success. So although I agree entirely with your logic in theory (since SUP DWing is more like surfing than yachting), by some strange fluke in reality it turned out in that particular case that the yacht designers got the DW board right and the flat water ones were much less successful. Weird, eh?

I'm pretty sure Ivan and Woogie had a fair bit of input with the the Dart.. I think even a surfboard designer/shaper would struggle to make a board that works well for DW'ing.. I'm sure Dale has made hundreds and it's only by testing and testing that they start to get it right.. That's what Naish, Starboard, Fanatic, SIC and DC does (and others like JP) and they need a very good team of testers that can give good feedback.. I think it's still early days for DW boards as most manufacturers try and come up with a do it all flat water/downwind board that's both fast and stable and deals with pearling issues of downwinding.. That design (in the original post) looks pretty good IMO but I'm not sure about the tail design and rocker.

At least the Farr office have designed some pretty quick boats over 4 decades. As for the no-name Coreban Turbo designer. Chances are there's a good reason why few have heard of them.

The back of the board looks like one of these: www.martin-raget.com/

The front looks a bit like this: www.volvooceanrace.com/en/theboat/1_The-new-Volvo-Ocean-65-cool-design-emotional-impact.html

Both are Farr boats

Here is a board designed by argy AC designer Juan K a few years ago before the Volvo Ocean Race for team PUMA.

www.thecarbonfiberjournal.com/?p=1290

Farr's boats have been typically slow recently and under performed in most conditions when compared to designers like Jaun K, Judel/Vrolik, Botin.

Still a good cross over of worlds though

That Laird/Puma race board should be renamed the Bariatric Race board..

before you do that wouldn't it be better to do it out of foam and epoxy construction first. lt's a lot of money if the board doesn't go that good.


most of the yacht and naval guys have come up with fast boards but usually very un paddler friendly.

and thats where most go wrong.


its the balance of fast shape and usablity that's the hard part to get right


andy- designers like these don't build.


some one else pays to see if its any good

Botin, J/V & Reichel/Pugh all seem to have Farr's number. So does Juan K if you can keep one of his things together.

Many moons ago I helped build a boat for a German crowd backed by Daimler-Benz. As we were building it we were coming to the realisation that this was going to be quite 'different' from current thinking and sure enough it was. The boat was launched and whilst it had very brief moments of blistering speed for its size, it was incredibly difficult to sail and more so to sail fast for any more than 30 second periods. Sitting on the side of the boat on one of our very many testing days, out of frustration, one of my Kiwi friends yelled:
"Who's the ****ing Rocket Scientist that designed this piece of ****?"
A German gentlemen sitting to the other side of me replied "I designed this boat".
Kiwi: "You call yourself a Yacht designer?"
German: "No. I am a Rocket Scientist."

Quite simply the thing was a Million dollar pig.

What you do say Laceys Lane is spot on the money. Absolutely loving my DC14 Coco Carbon by the way.
