The Love Muscle Medium!!. Already have the small and large, this slips right in between, so to speak.
237 X 55 X 84ltr, designed as a crossover speed/high wind slalom. Should be the machine for Nm's and Alpha's. This will put the Pit Crew back to the top of the ladder!!!
Hopefully Santa will be delivering it.

Looks sweet!

Looks good!!

Lizzy will be pleased.

Where do you put the batteries?

No batteries required, I can get it to vibrate by fitting a Select fin

Stuart Truscott of Dweller Designs is building it. He has made a CNC machine to cut the blank. What that means is all I have to do is offset my Alias "nurbs" surface to allow for the PVC Foam and he converts it to an STL file then runs the cutter paths straight off that. A few rocker templates to stop it bending in the Vacc bag, throw around a bit of carbon and resin and a board pops out. Well maybe not quite that simple.
I am really looking forward to seeing how it comes out.

Is it just me or is the mast track not centered?

Your right flatout it aint centre

Very observant but it's just a sketch .

do you want me to knock up a set of lightweight footstrapps martin

Thanks heaps for the offer Keef but I want to put adjustables on this one. That way I can get Spotti (AKA big foot)to take it for a 55 knot blast!!!

Oh, what a love-ly board!

The wingers disappeared, so I think it's not just a zoomed version of the smaller love muscle?

Your pics make me instantly missing a 85l open water speed machine in my quiver. So, as usual I am very curious about SRL-data and bottomshape.

Cheers, Fred

Hi Fred, The wingers on my other 2 boards have appeared to be succesfull, they are very fast boards and are performing beyond my expectations.They appear to both be really efficient low drag hulls. The small speed board is only being limited by my lack of ability and the big board is super slippery for a board of it,s size. I have done 37 knots on it without trying and I am certain it will do over 40. Not bad for a 69 cm wide board.
The design brief on this one is a little different though. The other 2 boards are about straight line speed and I wasn't worried about transitions. Due to the very parrallel outlines in front of the wingers they are pretty"stiff"which is fine for what they are designed for but not for this one.
This board I want to be an "alpha" machine. So fast gybes are more important.
Therefore I have curved the outline a bit more and removed the wingers, although I have still got a definite change in direction at 420 off transitioning into a quite "pinny"tail to once again keep wetted area to a minimum.
I also wanted to make the board easier to build as I was toying with building it myself( then chickened out)
I have used almost the same rocker as the larger board although the nose is 15mm lower. So it is not as flat as the small speed board. It is a progressive curve rocker, no actual flat with 1mm of tail kick.
It has a constant angle flat V right through, 1.5 deg combined ( .75 deg a side). This will handle chop well.
I may consider adding small cutouts in the tail at a later date but want to use it first to see what the top speed is like before deciding.

Some of the board maker with milling facilities use a program called Shape 3D. This system cannot read "nurbs" surface which is what most high end CAD systems like Alias that I use produce. Stuart can take my Nurbs surface and convert it to STL which is a mesh file. He can run his cutter paths straight off this.The only down side is that a high density STL file is massive so you don't want to be storing too many.

Stuart contacted me yesterday. He has finished the layup so will be sanding and painting soon. I am really looking forward to getting down to the PiT and see what it will do.

Regards Martin

martin you wont be disappointed with the scooped deck, i used it in the last slalom board i done and i swear it improved the board to windward, now that sounds like a stupid statement but the sail seems to be" locked in" and laying flat on the deck, ive also used some huge chine's, ive hammered the board off the wind in some big chop and the rails have never even looked like catching, so far ive got a PB 35.94 2 sec and constantly in the 33's and 34's, and after seeing the tail on your board i'm going to modify my tail cut-outs and make it a pin just like yours ,yep i think your on a winner there great effort martin

Hi Martin,
Wise selection.
As a suggestion, to start with you should shape the board yourself & have a 3rd party do the laminating/ finishing work.
Here in N.Z I send an Autocad file for the rocker/ deck profile to the EPS manufacture, there automated hot wire cuts the rocker & deck profile to my perfection. As the cost is relatively small $40, you can't go wrong. The outline & rails need to be shaped by hand which can be done quite easily with out an CNC shaping machine.

As a very part time custom board builder, STil away from commercial Surfboard shaping machines & Shape 3D as they are very limited functionality & severely overpriced!

High end "Alias" would be nice to have, but way out of my software budget.
I'm getting great results with Rhino3dm and have sourced CAM software as an Rhino Plugin. My CAM plugin looks very basic at first, after finding a way around Rhino mass of features & a little bit of experimenting I found that the CAM machine paths can easily be manipulated use the drawing commands in Rhino. The machine paths can be closed tightly or losley, what ever you draw will be the machine pathe, with accuracy (0.02mm)with full size shaping of windsurf boards down to highly accurate windsurf speed foils.

Damn its hot here in Auckland, Air Cond on tonight.

I would have thought a CNC milling machine would have difficulty with soft bendy polystyrene. The guys at Torquay used to mill board blanks but they used some stiffer closed cell foam.

Doesn't appear to be a problem but I think it is pretty difficult to get a really good finish even with a small stepover.
At Holden we do the full size clay car models with polystyrene. Milled about 30mm under. Then the clay is applied (it's sythetic clay) and milled once it has cooled and hardened.
I need to talk the General into milling some boards for me

on a different note. give the utes a bit more lenght in the tray and get rid of the flared wheel arches.

board looks nice though

Thats the same process I used to build a mould for a monocoque car chassis. Except we only milled 10mm under. Only needed to lightly sand it back after the final milling process for a smick finish.

6-axis robot cnc's are awesome, I want one haha.

Good luck with the board, looks awesome. btw how is the board that you had built by SSD holding up? I think he uses polyester instead of epoxy?

The Stoney is doing just fine, I really like this board. No durability issues at all and I can't stop looking at it every time I pull it out of the bag as it looks just great.
