LEON REARS

 

bigbay-3

Our new ‘Leon’ rear quad Leon Jamaer signature fins are now available! The fastest and loosest fins in the range. Available in both the regular ‘dynamic flex’ material and for the first time our new ‘Super stiff’ material. Ride like Leon!

Some words from the man himself..

“We designed a fin that is very versatile so I can use it around the world from Hookipa to onshore conditions at home. Most of the time I use 14cm and in my bigger boards above 90 liters I like to use 15cm. In general I would choose the soft material when I want more control in powerful or choppy waves. They guarantee a really comfortable wavering sensation. If I want a bit more speed and aggression in smaller or more onshore conditions I rather take the stiff material. In my JP Quads I put the fins to the middle of the slot box. If the waves are small and I need a super tight bottom turn I put them roughly 5mm forward or, when waves get above logo high, I put them 5mm back from mid position. ”

Leons

Choose the black logo for ‘Dynamic flex’ – Grip, looseness and control. The classic k4 material, chosen by all our team riders.

Choose the red logo for ‘Super stiff’ – Instant response and easy release. Our new material with G10 like stiffness.

 

LeonBlack

The Leon template for speed and looseness with it’s low tip area. We recommend going slightly bigger than usual with your front fins to give extra grip on the rail. Leon uses 10 Ezzy fronts with 14cm rears.

Updated production board toe measurements.

Leon in Cape Town

Asymmetric fins and toe in aren’t the be all and end all of wavesailing -for most people it’s not that important. We do 3 ranges of symmetrical front fins and only one range of asymmetrical which reflects this.

I still think it’s interesting to see how much ‘toe in’ boards have, and for those who want optimum performance I believe it’s a very important consideration. All of our team riders use the asymmetric Ezzy fins and not because we force them -they can use whatever they like best but choose the Ezzy’s. It’s also a major headache for us and the last thing we want as an injection moulding company as we rely on moulding large quantities of the same thing to be profitable (So having 3 different heads, in 3 angles and 6 sizes giving 54 separate mouldings is frankly a bad idea all round).

We do it because we believe it gives the best performance, and still no one else is prepared to do this (Witchcraft being the exception and the first to introduce asymmetric fins for their own boards).

So today I’ve measured a few more up to date boards. It’s good to see that the Starboard has a healthy amount of toe as their original quad had zero and there was some denial that this had anything to do with its weird behaviour in the bottom turn (It’s far more noticeable on a board with relatively big front fins which theirs had. Relatively small fronts can disguise the problems). Simmer continue to be bang on with theirs, and if you’re making yourself a board I would follow their lead.

What’s not so good is that I’ve felt the need to lie somewhat on my measurements again to save some blushes. I can’t stress strongly enough how important it is to not rely on these figures but to actually measure your own board yourself.

So if you want to know your box alignment, get your ruler out, measure to within a mm is near enough, and then use our calculator..

http://www.k4fins.com/toeangle.html

Your Tri fronts should have around 3º per side for the Ezzy asymmetric to work best (so if your box measurement is 1º choose the 2º Ezzy), and your quad fronts 2.5º (as there is a need to line up more with the rears, unless the rears also have toe). Symmetric fronts are best at around 1-1.5º.

K4fins welcomes Simon Dunton to the SUP team.

“I’m super stoked to announce I have a new sponsor – K4 fins!

simon

I’ve been pretty keen on K4 fins for a while now due to the performance, price and plethora of options available. I’m looking forward to being able to experiment a lot more with my fin setups to get the best out of my boards in varied conditions; as well as spread the K4 love and encourage others to experiment a little more and see how new fins can alter their ride.

I’ll be showing off these little yellow fins in SUP surf competitions later this year!”

K4 founder, Steve Thorp

“We’re really please to have Simon as an official K4 team rider. We spotted him and his huge ‘SUPNorth’ van at the beach a while back and noticed he had K4fins in his board. It soon became apparent that he’s the keenest guy out there and spends every possible moment working hard to become one of the worlds top SUP riders . We’re stoked to be able to help and support him on his path to success!”

K4fins Ireland storm chase

Stormy Ireland

We’re lucky to have an amazing team of global riders on k4fins, and it’s no different back home. Late last week I had a message from the two most promising up and coming talents in British wavesailing -K4fins team riders Aleksy Gayda and Jony Price. When there’s a crazy forecast looming these two are the keenest to jump in the van or onto the ferry and go score it!

forecast

With Jony now living back in Ireland, Leky and myself were able to get over on the ferry as foot passengers. It’s much cheaper this way but does mean taking the minimum of gear and clothing -not ideal when it’s 5 degrees and snowing, and 10knots to almost 50!.

We checked a lot of coast on Saturday morning, but there was only one spot clean enough to work in the WNW wind we had. It was extremely light wind but almost mast high. Check the pics of Aleksy Gayda..

A nice warm up (more like cool down!) for the main event on Sunday.

Big Sunday!

We had grand ideas of scoring this little spot near Mullaghmore again, but unfortunately it proved to be too onshore this time. Last time we went it was perfect mast and a half barrels but no camera man..

gspot1

So we headed up to the NW.
It was howling. It was raining. It was way over mast high. It was closing out on the inside. It was freezing! There were to be a lot of big swims with claw hands!
It wasn’t easy to get pictures -big thanks to Jony for persevering!

We also caught up with K4fins Irish team rider Oisin van Gelderen who stopped by for a quick wave sail between epic speed sessions! It was windy!

The toughest conditions we’ve sailed in for a long time! Full power 3.7, mogul like 3 foot chop on 2o foot faces, too much wind to sheet in at times and numb fingers. A good test for the fins! Ireland has everything!

A great weekend, we can’t wait for the next one.

Grahams K4fins set up insights – PWA Maui – 2014

JohnCarter_Taka_from_Ezzy

 

My flexible K4 fins give me a massive advantage over most of the other riders who use stiff G10 fins. You can see it in my carves– I can keep speed as I redirect. 

Before the event, I played with a lot of different setups on my boards, which are all tri-fins. I tried using all 12cm Carves. This made my boards super loose but without enough drive. After, messing around with dozens of different options in my boards (of which I had 5 setup for the contest), I settled on a classic 2+1 setup: 10cm side fins and 16cm back fin.

I use the Flex 16cm for the rear and it gives me the confidence to put all my strength onto the rail. The fin is deep enough that I don’t have to worry about spinning out. And no matter how hard I push, the fin bends rather than cavitates. In the Aloha, I was able to keep the board going rail to rail better than a lot of other competitors (I racked up 8 point scores with just rail turns), and my fins make this possible.

On the side fins, I use either the 10cm Stubby’s or the 10cm Ezzy Assy with 2 degrees of tow-in. I ride the stubby’s when I want to do more slidy tricks and the Ezzys when I’m looking for more carves. The Ezzy’s have a ton of drive and acceleration in the turns– which is amazing. And the stubby’s don’t track as well in the water but that makes them easier to release in the tricks like the taka.’

How fast can a composite plastic SUP race fin go..

Marcia YorkPhoto courtesy of Marcia York

We’ve been busy designing a SUP race fin. We moulded the first offs last week and I was pretty chuffed with the results -it looked fast! I started to wonder just how fast it could go…
So I decided to try it in my speed board. Jon Kennet from MOO CUSTOM kindly sent me a Tuttle head to resin on, and it was good to go..

 

speedSUP

As luck would have it we had a windy day at West Kirby on Sunday (see top pic by Marcia York). It wasn’t all time fast conditions, with fairly light winds for speed and a broad course with rolling chop, but it was a lot of fun and fast enough to put the fantastic plastic through it’s paces!-It was rock solid.

So just how FAST did it go?!

A peak of 42knots (48mph or 77kmh) on the GPS and a 500m time of just under 40 -the fastest 500m of the day!

Results on GPSSPEEDSURFING.COM

That must be a record for a plastic fin, and it wasn’t optimised for speedsailing by any means, it’s our SUP weed race fin…

SUP24b

Soon to be available in 21 and 24cm, once we’ve tested it on the SUP race course.

IMG_20140608_171759

We’re stoked to announce that Spanish racer and ripper María Andrés has joined the K4fins team. María is a great ambassador for windsurfing and also a keen Stand Up Paddle-boarder (and editor of supingmagazine).

captura-00052

 

We asked María what she liked most about the fins..

“I love my new K4fin set for wave riding because it gives me enough grip for a controlled bottom turn without compromising the speed, to hit the lip where I want. And the Cut backs are awesome! -they are loose but in control!”
