Hi guys - Im new to this forum - but i have been building and testing etow myself for a couple of years now… my build is getting closer to a commercial unit all the time - I do heaps of foiking and use ny builds as foil coaching tools for newbies wanting to learn to foil for a job now… we build Biaxial carbon foil boards too - proper foil brain issues 
i am yet to conquer steering from the remote… probably my final hurdle …talking to BreMote dudes now…
Hey Mark,
I am also based in Vic, planning a tow build. I am not sure if you are building or sourcing your batteries, but would you be interested in selling a standalone battery back?
yeah mate sure - im releasing all our our etows as DIY component kits…
batteries / props / hull / pro guard and motor mounts are all designed to be interchangable depending on your foiling or wake affliction …
Weve gone and spent a lot of tine of batteries designed for etow - they have to be able to handle big outputs for a long time - one for up to 6000w motors (1 -1/2hour full noise) - So were using the expensive samsung s50 cells - and the case is a china import made to fit 14s6p… be doubled (2 batteries) to run up to 12,000 w (twin 6000w ) for wake tow or surfboards… or just to double the foiling range to 3 hours plus…
Ive got the first shipment due here in a month…
pricing to be finalised but around $1k gst inc per battery is what were aiming at…
the case and ports are ip67 with sb 50 anderson connection used for charging as well as output… it has insulating waterresistant rubber boot as per our shitty post production pics attached below…
excuse my spelling im all thimbs.
hahah… you’ll find me on the phone via my website - hsfoil.com - the components lists on etow is actually really massive…
That sounds awesome. Keen to see what other components you have available before I start ordering parts. I am pretty comfortable with 3D modelling/printing and composites so keen to build my own hull eventually and motor pods etc, but my electronics experience is very limited and building a large battery pack is beyond my comfort level currently.
I assume you are aiming for steering via a rudder, as that photo looks like it has two fixed inline motor pods?
yeah ive got two variations built and operational - one is single 6000w motor and about to have rudder steering…
The other is the ‘aligned’ twin motor version - shown in the picture…
the ‘inline motor version’ there is amazing though headwind chop - and has great take off torque - it runs twin 3000w motors - and opposing props…
i could add servo rudder steering to it - I did test rudders at full 45degree left and right to see how it went
The issue of course with twin ‘aligned’ props was that rudder steering starts to get pretty ineffective - its got like a 25- 50m turning circle!!!-
very happy with that model for a good year or so its been u real - I see it now as the stepping stone that really nailed the hull shape design that handles 20kmp+ into heavy chop…
the twin props really ‘pull’ the hull through chop with one prop semmingly always in the water as chop is crested you dont get the power surging issues or the jumping around ive experienced with other etow ive tried…
I love it on foil - its lack of steering has never really been something i needed personally - Until i started surfing Sanur in bali and saw that without the steering id have had like 2km paddles back…
The differential motor ateering on side by side prop set ups look to be capable of really sharp turning if required - u real for picking up students while coaching and facing them in the right direction at low speed…so thats my next build …
imnsure it will have its issues too - but Ive got through most of the big hurdles on the first 5 operational etow… im up to like version 48 now
everyone that sees my etow goes like " thats amazing" man thats the best - how do you steer it?" and im trying to explain that if you pull out left on the rope - it turns right - its really simole and intuative - but seriously no-one gets it… Im iver explaining. its a feature that people want on etow even if ultimatly once they are learning more they will use less and less…
