Phill, bring the camera, for a Pictorial !

Looks really small compared to the big Naish surf that works well.

So when do they finish shaping it

I can time trial that fin too !! I know someone who got one very recently !

We will have demos of the WG fin at the Roar.

Cheers

Imagine the weeds you could catch on that..

Good to hear about Aiden and Andrew.. Both great blokes.

Will you have them for sale ?

Rob you will be able to order them from us for delivery week after the comp. We are testing them first. Feedback so far is V.Good, both as a DW fin and a surf fin.

AA I would be very interested in your feedback on this fin. The high aspect I understand the very small winglets to avoid 'tip vortex' I am not so sure. The very thin foiling and Lexan construction are also different to common understanding about performance but like all things the proof is in the pudding. Be sure to let us know the combined feedback. I'd love to have a go. I paid my mortgage for many years selling fins so these kinds of things interest me greatly.

We'll probably start a new thread, with pics from tonight....

3 different fins made very marginal difference for me on the Naish 14, over 400m, with 1 turn (2x200m - out and back). The 3 fins were the Naish 14 Standard Fin, this Winged Fin in photo, and an 8 inch True Ames Al Merrick Channel Island Generation 2 Single Fin, with loads of rake. Photos to follow.

The legrope / leash trailing in the water, added maybe 3-4 seconds over 400m. Very marginal. But that becomes roughly 10 seconds per km.....

The Naish 14 Standard Fin probably points the best, allowing up to 12 strokes on 1 side (with minor wind assistance).... but by pausing to swap sides, you get a free little glide and rest, and seems to make little difference overall....

Essentially, slightly inconclusive, more scientific testing required !!

My first run was 3mins 7secs on the Naish 14 Fin, and all the other runs were peppering 3.08/3.10/3.11/3.12..... what effect does muscle fatigue have.... ???

Have fun in the water people !!

You guys need to go to the nearest windsurfing shop and have a look at the range of race fins on offer and wave fins. Windsurfing has cover a lot of ground in relation to high aspect ratio fins and designing in twist etc.

There are now a heap of fast weed fins on the market to.

Most fins in the sizes for a SUP come in configuration that will fit fin boxes on a SUP.

I agree.. but they aren't cheap.. In fact they're very expensive and for very little if no gain at all.. IMO.

Those nice dagger/pointer type windsurfer fins are great for high speed.. Not us..

They are great for pointing into the wind (while planing).. again Not us..

They are not good for going down wind or going slow... Now that's us..

..and not most will fit our fin boxes.. it's very few because most use power or tutle boxes in windsurfing boards.

The other thing we found out was that the rider and board weight makes a significant differnce as to how well the fin board combination performs.

It would be interesting to see Jonathon try out one of these fins.

The board on the Left of Picture.... I saw this a while ago, and initially thought it was a Naish 17, but it has a square tail (Naish 17 has a rounded pin). Decals a logo's on it looks like Naish too.... the one on the right is 15' x 30" according to the advert.... the other could be 16 or 17.... x 27..... Or is it a future Starboard ???....

Did Cheyne and Ben ever have a patten on the winged keel fin ? I have an original shortboard fin signed by both in the trophy cabinet a keeper for sure

I like the shape of that new Starboard Bamboo fin.. How many inches deep is it Jonathan?

I reckon that white board next to the K15 is a Naish 14' Glide.. The pic is slightly distorted.. and it is very odd to see a Naish in a Starboard advert.

Starboard do have a secret DW board coming.. Maybe they copied the Naish 14..

a lot of opinions about this fin. i got a lend of one for a few hrs. tried my fin, the grinder, my fin again, the grinder again. on my 14'( the rocket), i believe it is faster. but the best thing is the board bobs around less and generally behaves better, which means faster. jacko and myself have found at training the flatter boards get thrown of line easily in broken water and other boards wakes. i believe this fin will be able to 1/2 that disruption. hopefully there will be a lot of knockers and i'll be one of a few that is going to get one
cheers
ps imho the right fin/rudder on a dw board is just as inportant as surfboard fins

The Starboard Bamboo race fin is 8" long if you measure vertically down from the bottom of the board. But if you measure form the centre of the section that goes into the fin box to the centre of the tip of the fin it is 12" long (that is 12 inches from where it comes out of the board, not counting the insert section) - it's a substantial fin. Still haven't tried it yet but will in the next day or two and report back.

It's so swept back it really looks like a weed fin.

Andrew Allen from PSH has given me a set of the wavegrinder thruster fins to tryout at the Roar comp on the weekend.

Not sure on what they will do ,neither is he as nobody has tried them yet.

I will have to wait for some swell as it is flat as here on the Goldie, and will post the results as I will be trying them on a 8'8 and 9'6 in both quad and thruster setups.

DJ... I can't knock it till I try it
