kobo said..JB said..Had an awesome bay DW'er yesterday and thought i'd share it. This run was on Pittwater in yesterday's southerly. About 20kn, and just as the sun was setting milking the last of it.
This is running form the land locked end of Pittwater out to Broken bay. SO no swell, all wind chop with a relatively short fetch.
Riding the Naish Hover 120, JET 2140HA/310HA on 64cm Fuse and 75cm Alloy Mast. A 3 degree mount shim and a 2 degree rear wing shim. I also drilled an extra hole an inch further back to alloy me to mount another inch further forward. This is the ultimate lift pig setup.
Enjoy,
Ride safe,

2140 sounds like a huge wing, is it easy to get overcooked on it ? And how does it turn ?
Hey Kobo,
Yes it is a big wing, I use it a lot as I love the lift. As mentioned I had everything shimmed up. I am 6'2" and 90kg +/- and can wind the 2140 out to 30+kmh and bomb most swells that we generally get on a light DW'er. It turns way better than you would ever imagine.
Something that a lot of crew are still working out is the importance of matching your Foil speed to the bumps you intend to ride. In that video, I am riding in a bay with no ocean influence at all, no swell and only short fetch chops. This means they do not travel very fast. So there is no point in going fast on your foil as you'll just out run the bumps very quickly and end up having to pump a lot (If you were racing, then yes, you'd use the smallest foil you can get up on and pump your ass off), the 2140 allows me to run super slow and use the bump energy, and thus I do not need to pump very much at all.
Looking at my GPS playback, I can see that taking out the max and min speeds, I am sitting between 15-19kmh pretty consistently which does reflect in my average speed of 17.9kmh. But the cool thing with this foil is I also have lows in the 12's and highs in the 24's. This is where the gold is on this foil - Usable range!
If it was an ocean run with good wind, then I would definitely look at running the 1800HA or even the 1400HA. This would respectively move those scales up to something like - 1800, 17-22kmh (13's - 28's) and 1400, 18-26kmh (14's-30's).
Being a more generously proportioned rider has some exponential disadvantages when it comes to DW'ing on all craft. Being heavier you're not just having to move more weight on tiny power sources, but you generally require bigger equipment also to get going which also adds extra drag. So extra weight of rider, extra weight of larger gear and extra drag of bigger boards and foils, you get stung harder as you get bigger. BUT!!! Once you're up, you can hold a bigger foil for longer, and you can also hang on longer and overcome huge lifts where a lighter rider wouldn't. Being able to ride a bigger foil can have advantages in the small stuff provided you can hold it on the big "sets". But the big one is always just getting up and not just getting up, but getting up with the energy left in the tank.
I love DW'ing and I am not really in a rush when I'm up. I quite like going slow and see how well I can get in sync with the bumps, see how little I can work. On a hard day, I may have to come down and rest to get my heart rate down, BPM can be well into the 170's and averaging 162 BPM, then days like this one, I am staying below 160's BPM and averaging 146 BPM. This makes a huge difference.
Looking forward to my next run.
Ride safe,
JB
