Here we have a performance Twin pin again, but this time the design has a more balanced outline where we have the wide point at centre instead of forward. This gives the board more of a short board feel rather than a mid-length wide point forward outlines.
This one can be shaped as a small wave short version or a blown up longer shape.

So on top we have fa lat or double concave deck ,with beveled rails dropping the rail down to a nice medium boxy rail.
The entry rocker is easy going, and fairly low out of the tail on the centreline rocker, but more curve on the rail.

You beauty!

So here on the bottom side I have a slight panel vee with the double concave scoop inset.
Twin channels and dropped wings beside the fins all work together to keep this free turning board gripped to the face. Run it as a straight twin or twin plus trailer.

A Performance twin with the early 80s design theories in mind, with 2022 rockers and fin set ups.
Features like the flat/concave deck give a super stable but also reactive top side.

The Garage find has a vee bottom with a scoop double concave set inside of it, dropped wing channels set between an upright twin fin set up, giving plenty of grip and projection through tight turns.

The wings set behind the fins pull the tail in a little, giving awesome sensitivity under the back foot plus extra grip from the downturned wings.
This board could sit right between your performance "Thruster" and your "Fishy" twin fins.
Surfs great in the 2-5 foot range so is a great "one board quiver" for waves under 6 feet.

"This just might be the best fish I've ever surfed - its definitely the fastest by quite some way" Scotty.
This comes from the Lis Fish template. The "Fresh fish" has a traditional outline and rocker, the deck side however carries some more modern advancements.

Stock dims at 5"11 76kgs are 5'9 x 21 x 2 3/4 equates to about 36 litres.

Features a double concave deck which enables this design to carry heaps of foam but still feels reactive under foot pressure as the toes and heals are pushing on the rails sooner (as they don't have to push over a curved surface - the surface is curved backwards towards your foot).
The concaves also make the Fresh fish a super stable board to paddle as your chest fits snuggly into the curves of the concaves.
The down/beveled rails on the deck lets thicker boards have nice low and sensitive rails, so it's thinner and engages in the wave easier.

Features Scotty's signature scooped concaves and the bottom shape configuration is where the board gets its speed from.
Technically, it's a spiral-vee double-concave, set in a single concave which provides the lift needed in slow soft waves.
The vee helps it roll over onto its rail, and the spiral vee expels the water diagonally out the tail because we don't usually surf in a straight line. Set up as twin fin. Scotty's been riding Hybrids from Hotdog Twinny fins which have been amazing.

This is the top end of my designs when it comes to performance twin fins (optional trailer also).
A step away from traditional designs, this one looks like it's from the future. All of the feature in this design is function over form.
Loose and fast is my first design philosophy, then I add elements that will give the design control.
The Rock n Roller is high performance, high speed, to be ridden the same size as your short board.
You'll also get a super comfortable and stable feel under the chest whilst paddling and getting to your feet for such a small board.

Starting with the outline, the wide point just behind centre gives the board a pretty narrow and light front end and less swing weight.
But it also gives the outline a lot of curve in the area behind centre which gives it an amazing turning circle.
The triple wing is there to give it some straight edges through the tail for some added grip and control, kind of like small teeth biting into the wave face.
The diamond tail just suits these features and continues the flow of the overall outline.
The R 'n' R also has a double concave 3/4 of the way along the deck to give the board a super responsive feeling. You can push on the rail faster as the rail doesn't flow away from your heels and toes, but rather curves towards them allowing for a fast reaction when food pressure is added.

So we have my scooped concave with downturned fliers on this one. The scoop concave consists of a single concave that has a spiral-vee double-concave sitting inside of it.
This leads to the downturned fliers behind the fins. These give the board lift, and the ability to still roll over onto its rail easily for a board that has so much concave.
Obviously the lift equals speed. The rocker is medium, and the rails are a low boxy variety.
Designed to be an all-round performance twin to have the ability to ride waves in the 2 - 6 foot range.

The GT is a mid length design for those that want a board that's loose for its size and paddles like a beast.
Like the Twin Pin design it can be ridden in small and large waves, but best suits 2 - 4 foot range with a slopey face.
You will have plenty of glide but it's loose enough that you can still turn in less than powerful waves.
General rule of thumb in my mid length range, the GT is the grovler for smaller softer surf: if the Twin Pin is the baseline, and the Winged Pin is the step up for more powerful and hollow waves.
This is the board for you if you live or mainly surf soft slow waves.

Featuring a very flat deck with beveled down rails that run into a mid boxy rail. This gives plenty of paddle power from the flat deck holding a lot of foam, then the beveled rail lowers the deck line down to a nice performance-style boxy rail.
The rail starts soft in the nose and flows to a hard and sharp edge through the tail.
The outline has the wide point two inches forward of centre, that's foam under the chest for paddle power.
The wings set just behind the fins pull the tail in giving it the quick response from rail to rail, and the ability to hold in when you have too, if you find a steep section.

There's a little more rocker in the GT than the Twin Pin, mainly in the nose. This gives the GT great turning abilities in smaller waves for its size.
The bottom shape configuration is where the board gets its speed from. I call it the "scoop" concave, but it's actually a spiral-vee double-concave set in a single concave which provides the lift needed in slow soft waves.
The vee helps it roll over onto its rail, and the spiral vee expels the water diagonally out the tail because we don't usually surf in a straight line. In front of the scoop it has a very slight panel vee.
All of these attributes give the GT a free flowing feel that always seems to have the speed you need to go wherever you want on the wave with little effort.

This is designed as a “step up“ board.
Can be made smaller but it will be most at home in over head waves with some power.
Set up as a quad fin. They are well known for their speed in the barrel.

The Top side features a flat deck and beveled rails which run into a beak nose.
This will give you plenty of paddle power.
Low to medium boxy rails that are very low through the last 12 inches.

Has a generous rocker. The bottom side's main feature is the scooped out double concave, that sits in the deep single concave, which leads into the down turned wing, with vee after that coming off the tail. 

My best seller. True to it's name.
This modern retro performance twin fin is an easy to ride, loose and fast take on the late 70s design.
This little beauty is suited for waves in the 2-5 foot range with a little more curve on the wave face.
Great for beach breaks and draining point breaks.
Standard size for a surfer of 75 kgs 5'10" - 5'8 x 20 1/4 x 2 1/, 33 litres.

A flattish deck meets a beveled rail to have the best of both worlds in the volume on the deck, but not on the rails.
Fluted fliers to drop the rail line even more, which speeds up the rail engaging process and increases grip and projection; and of course a beak nose to tie the rails together at the nose.
A deep but not too deep swallow tail finishes off the shape nicely.

So here we have a generous entry rocker, and a low to medium tail rocker allowing the water to flow easily under the front foot, and out through the double barrel concave and twin channels. These are set in a vee.
Sharp edges especially behind the fins, work well with the fins and the fluted fliers to keep this rocket gripped to the wave face.
Can also be run with a tralier fin if that floats ya boat.

So this little puppy derives from the original fish. The Steve Lis fish. The outline is the same, bar the little "hip" I've put behind the fins to add a little break point to an otherwise straight outline. This gives it a little whip.
The beak nose leads you to a medium to low rail which is easy to get in the water.
Standard size for a surfer of 75kgs 5'11' - 5'7"x 20 3/4 x 2/5 33.6 litres.

The features here are obviously the channels, which you can either go with or not. I've cut them deep and relatively short just here for grip. And grip they do!
But if you like your fish a little bit slippery, then this model comes with a double barrel to spiral vee out of the tail end as well.
Ah ... the pleasure of a custom board.

As far as the bottom contours go, it has a medium entry rocker and a low tail rocker, with double concave to vee out of the tail with four deep channels.
Otherwise the double continues through a spiral double barrel out of the tail.
Suited to waves in the 1-4 range but can be ridden in bigger.
Eats flatter face points breaks for breakfast!
Can be run as either a twin keel or upright twin fin configuration.

Another classic outline and over all design that can handle almost anything the ocean can serve it.
An easy shape to mould into almost any size range.
The beak nose and beveled rails keep the foam on the deck and the rails low and responsive.
Standard size for a surfer of 75 kgs 5'11, 6'8"x 20 3/4 x 2/3 43.9 litres.

The bottom side sees a double concave into vee under 4 channels.
A mellow but not flat by any means entry rocker.
The tail rocker mimics the nose, easy and flowing.
I usually leave a nice tucked edge from nose to tail.

I have a few different configurations for the channels: usually 4 but with the middle channels either long or short.
Can also run this 2 or 6.
Fin wise most people would run it with uprights but keels could work. Also, you could even run a single fin box in it if you wanted the option.

The Savitar is a performance mid length style design.

Taking some of the best features from my tool belt I've designed this one to be ridden when the surf is head high and over and with running points in mind.
Stock dims for me are 6'8 x 20 1/2 x 2 1/2 or about 38 litres 5'11, 76 kg.

So the Savitar had a flat deck and of course my beveled rails and beak nose. A nice balanced outline with the wide point just a smidgin in front of centre.
The winged diamond tail feels like a swallow tail but surfs a couple of inches shorter when you step back on it and push it through a turn tight in the pocket , the flat deck give it a nice stable platform to paddle and stand on.

The bottom shape configuration is where the board gets its speed from. I call it the "scoop" concave, but it's actually a spiral-vee double-concave set in a single concave which provides the lift needed in slow soft waves.
The vee helps it roll over onto its rail, and the spiral vee expels the water diagonally out the tail because we don't usually surf in a straight line. the rail channels grip on the wave like fins and aid in hold and projection and channleing water off the tail ,
