Woodie Wake Plank by Andy Cross ( Wolfie)

Length 134cm

Width 40cm

Rocker 4cm continuous

Concave 5mm

The board was designed as a progressive freeride / freestyle board for flat water / light chop (typical UK east coast conditions)

Based around a 10mm cedar core thinning out from the last insert to 3mm at the tips before glassing

Medium flex with 600gsm triax glass on both sides (I would use a lighter cloth probably E glass in a couple of layers if I were to make it again say 2x300g or 3x200g or possibly 2x200g with a 200g +-45 biax as the triax has removed nearly all twisting under load)

Core is tapered 45 degrees through the thicker sections down to the 3mm rail

Tested on a wakeboard cable - planes very well, the tapered rail holds a very strong edge when loading up, the flex eats chop without eating your legs but for my preference I would have it a bit stiffer. Rides like a tea tray if you take the fins off!

Currently the board is still out in Morrocco being tested with a kite so I am awaiting feedback on that one

The DXF is reduced for a 10mm rail

BOARD OVERVIEW

The WET DREAM MK1 is a great fun board for the intermediate to advanced kiter. It has a very easy edge to edge control with a progressive rocker making it an excellent wave twin tip. The even flex of the board  tip to tip gave it a very smooth release off the water and soft landings. It does not boot you as high as most dedicated twin tips but it by all means has got some solid pop for a board as forgiving as this one.  Due to a flat bottom shape, the board is very forgiving in flat water while learning rotation trick such as blinds. Although the flat bottom does create a very loose and lively board at high speeds making it a bit scary for beginners.

Wake Up - Wake Style Board

B8 - WakeUP (Built)

I recently rode a Slignshot Darkside and loved it. It literally threw its self up the front of the waves at such a speed that it felt like have a rug pulled out from under you. Inspired by what I could see from an outsiders view I've designed up a board with some similar attributes. See the latest version of Boardoff for the 'waketyle' templates for the exact parameters.

a. 138 x 41cm, multiple deck. Paulownia lower deck and PVC foam for upper deck.
b. 31cm wide tips ( quite tapered for ridding in chop)
c.Fins inset a long way into the board and will use smaller fins , maybe 1 ". Not sure exactly why this is the case in the Darkside. Will be interesting to see. My guess is that it just locates them closer to the center to assist enhancing the mid-section rails ability to grab the water without having the strong direction righting force of fins at the tips. Also, potentially keeps both fins in the water and so improves up wind ability that is lost with the more curved sides.
d. 50mm rocker, 2 stage but very close to continuous rocker. Mid-section slightly flattened for around 150mm.
e. 6mm concave.
f. Very stiff - about 15-20mm tip flex under 20kg load based on model

B8 - Wake style 'The Wake Up Call'

B8 - WakeUP (WIP)

I recently rode a Slignshot Darkside and loved it. It literally threw its self up the front of the waves at such a speed that it felt like have a rug pulled out from under you. Inspired by what I could see from an outsiders view I've designed up a board with some similar attributes. See the latest version of Boardoff for the 'waketyle' templates for the exact parameters.

a. 138 x 41cm (long)
b. 31cm wide tips ( quite tapered for ridding in chop)
c.Fins inset a long way into the board and will use smaller fins , maybe 1 ". Not sure exactly why this is the case in the Darkside. Will be interesting to see.

d. 40mm rocker, 2 stage but very close to continue rocker. Mid-section slightly flattened for around 150mm.
e. Zero concave. Reinforce mid section with carbon to stiff it there.
f. Medium stiffness, in middle by using 7mm wood core with carbon just in the mid section.

B6 - Mini Me

B6 - Mini Me (Built)

Small stiffer version of B5 - Light Wind Board. 130 x 40 cm, 30mm rocker, 5 mm concave, 8mm paulownia wood core made in 2 layers. Designed with freestyle in mind and for bigger wind days in the surf.

Layup as per B5 with the addition of precured topsheet and 200gm pre-cured layer of resin on bottom. 8mm core. Rocker line same as B5.

Comments: Board has only just been out on the water one time. Too little rocker in it as a result of using rocker jigs for B5 - Light wind boards. 8mm wood core with same layup as light wind board with the exception of using precured skin on top and gelcoat bottom surface. Twice as stiff as the light wind board. In initial runs, the board threw up a lot of spray off the fins. Suggest moving fins in towards center at least 30mm. Suspect this is better on flat water. Pop was excellent, easy to jam rails into the water to load up. I think that this board needs more taper at the corners and mezzanine section to be a comfortable ride in the surf. Corners turned out squarer than on light wind board due to the way BoardOff Scales the design and me not reducing the tip width sufficiently.

Update : I remade this board outline with a different core. The core is the 6mm constant thickness core that I used in the light wind board. The experience of riding it was very different. The thinner core makes it much more comfortable ride. The board still absolutely trucks up wind and similarly still throws up spray off the corners.

No carbon on in the core either. 450 gm stitched eglass+graphics+180gm plain weave eglass and post cured it at 50 degrees. 

This is a better boards than the very stiff core version but the spray off the corners limits the range of chop that it can be ridden in. I had it out in the surface and the wind chop at around the 20 knots made it nearly impossible to ride as the spray continually distracts. As it dropped of to 15 knots the spray all but vanished.

I watched the corners when the spray came up and it it occured when edging and typically only about 2 -3cm of the corner would slice through the water and kick up the spray. i think that is all that would be required to rid the board of the spray problem. 

On flat water it was excellent. Rails really locked in and made it really easy to load it and almost pull the kite to a holt. Needs a few more days testing to really feel it out.

B5 - Light Wind Board - The Levitator

This board is the 5th board I have made and is hands down the best board I have ridden for our local conditions ( choppy, surf, many sub 15 knot days).

++ Rides over chop like a dream, soft ride, excellent upwind, gets going in low 10 knots with a 12 m kite ( 77kg), light so it doesn't feel like a large board.
- 44cm width can make it hard to load the edge and hold it when wind hits high teens. However, I used 2" fins and the set up was fine for 20 knots conditions. Messed up finished but may have started a new 'leper look' for kiteboards future. Yet to be really stress tested in big surf. [Update - not problems in surf, big surf too)

Construction

Its big at 137 x 44cm. I made it with just a single layer of 6mm paulownia wood planks.
35 mm rocker, 5mm concave.

Layup:

160 oz e-glass
450gm stitched e-glass
65mm uni-carbon straps for torsional stiffness
6mm Paulownia core (with 4oz e-glass reinforcement under footpads)
repeat as above.
Epoxy, ABS rails (4.5mm)

IMPORTANT -  Footpad holes are 6.25" not the standard 6". Fin hole spacing 38mm.
Due to the thinness of the board you'll need to drill footpad insert holes all the way through or risk delamination.

IMPORTANT - Plans assume 10mm rail material. Outline is reduced for by this amount as the plans are for the template to route this.
