I've ridden these shapes loads of times at 18 to 24 feet at reefs, points and beaches and they just keep on going better as the size increases...




have you got some pics Roy.

You're right, it is a pin tail!





These shapes ride about a foot shorter than their length so this one is equivalent to something in the 8 foot range.




I thought the idea was to get a shorter board that paddles like a longer board...not a longer board that surfs like a shorter board?



There are two main directions for paddle in guns at present; shorter boards with plenty of volume and longer boards with plenty of volume.

This one has plenty of volume... the point is that these shapes handle lshorter than their length suggests in terms of the ride but have the paddle advantage of length. so at 9'5" she'll paddle like a 9'5" but ride a bit shorter in some respects.

One of the features which i like about this sort of shape is the ability to turn at speed anywhere... sure they are not for hacks but that's no big deal for essential surfing.

The current types tend to be stretched out versions of boards designed for point scoring moves, this comes at a price in terms of control when taking off and positioning at speed. That's my theory anyway.


Good luck I look forward to some ride reports and videos...am very interested to see how they perform

I worked it out it looks alike one of those Meyhoffer thingies without the big cuts outs

I wonder if its a noserider for big waves?

Ours came first by at least a decade, but yes there are some similarities especially to the 'slip in'.

The second gun shape will have a slight incut near the tail also.

Mind sharing the theory on that...I would of thought that consistent rail line would off been the go rather than having a area where the water changes direction....especially on a big wave where you potentially have a lot of surface bump coming at you...I have really been that keen on flyers and bumps in the rails for that reason

It's foil theory... reduce the planshape curve and even reverse it slightly on the trailing part of the foil. This allows better flow mixing at the tail and a section of rail at the tail which is basically straight for precise control.

There's no bump or flyer involved.

Handling bumps and chop is one of the main reasons for the extreme pin displacement tail. When the planing area at the tail ios very low, with soft rails and plenty of thickness then the tail sinks controllably and in a self tending manner when the nose kicks upowards as it hits chop. This brings the pitch pivot fulcrum closer to the rider so the rider is at the 'neutral axis' and doesn't get jammed up and down as much when going over bumps and chop.Such tails handle chop way better than conventional planing tails, even the narrow ones.

The rails themselves have a constant section below the tuck... no changes or taper at all... that also gives a consistent response.

To clarify I'm reporting heights the way it's done in the big wave arena i.e. actual face height.

Translated into the usual lingo means 9 to 12 feet.

Plenty of spots handle that size and/or can be ridden when out of control.

Finished the shaping today, all but.


Surfing the points tomorrow and finishing a woody friday so glassing will commence on Saturday.

Very funny but at 24" wide it's no standup.

No doubt you are referring to the faceted rail, which is used to maximise volume at a given thickness

Whatever, I was making 27" wide 2" thick longboards for years before the SUP craze.
