The longest non-stop leg

Postby BraCuru » Thu Oct 24, 2019 10:12 am

Wonder to know the longest non-stop leg on one tack known or experienced by you.
How to cope with numbness, fatigue?
What gear to use?
What accessories are handy?
Any tips?
What average speed etc?

I am preparing for a 5 hours crossing - most likely on one tack.
My best so far was 90,5km in 2h58m, average speed 16,5kts (30,5kph), hard upwind in 80% of the leg, two falls, no breaks.
It could be longer but that day Baltic was too narrow ;)

Moses Comet and Flysurfer Soul 8m. Bracuru Hover board. NP Race seat harness without a spreader bar. No depower control system. Xcel Infinity 6/5mm wetsuit. Kayak vest with a camelbag.
No assisting boat. Solo trip.

Impressive. Maybe a bit crazy :-)
What stops me from doing this is safety. I have been en trouble once because of fatigue and and a long swim.
I often foil solo, and bring my mobile in an aqua-pack and some glow sticks. You can now call 112 with gps coordinates (country dependent).
What is the next level? VHF or Garmin inReach?

Vhf when you are immersed doesn’t work well to cover distance. It is line of sight. Even in a small boat a handheld is 1-2m antenna height. Floating in water it would be -0.3 (!) to .5m. Doubt effective range would be 5km to another surface bound user. A plane might hear you, or a far away ground station with a high antenna. But once they come out to help in a small boat they would have a harder time.

Go for the satellite messager/epirb type device if you can afford it.

The formula for line of sight (vhf) transmit distance is:
distance in nautical miles = 1.32 * (antenna height in feet)^0.5

I haven't done anything close to 90km on the hydrofoil. I did 20km one time in 30 knots choppy/lumpy sea. That was HARD. Made harder by the fact I was overpowered and it was a stupid pitchy short period swell
Oh I did do 90km downwinder one tack one time landboarding. And a 24hr landboard which I did 245km. but that was forwards and backwards.

Why not just ride toeside when you feel the need to rest the back leg?

Seems like you already have more experience than most of us here re long distance hydrofoiling.

My lessons learned from the 24hr landboard was this. Its the small things that get you. Things that you don't expect to be a problem because they aren't a problem during normal riding. I hadn't trimmed my toenails as an example. They pushed into the end of my shoes and hurt like hell. I had do stop and trim them partway through. My harness wasn't supportive enough for 19+ hrs of 30+ knots if was painfull as hell. I ended up wearing two harnesses. One to hold the power, the other to distribute the load. Then random bits of that sand got into various placed and I got rubbed raw.

You get to a certain level of pain and just seem to carry on at that pain level if you have prepared your body enough. But if that harness digs in a bit much or there's a pointy bit in your binding that is what will kill it for you.

Take extra special care with finding comfortable gear. The same goes for the kite. Ensure you have an easy to fly huge depower kite. I'd suggest you probably want a depower system. You need as much adjustability as possible. The wind can change alot throughout the day. I'd almost suggest you rig a race style depower system so to can trim the kite to optimal power setting whilst having the bar all the way out. That way you dont have to hold the bar in to 2/3 for the whole journey.

Food wise, I would council against sugary drinks and any short chain single sugars. Go with longchain carbs which give a slow release throughout the day. You don't want a sugar spike and associated, lull.

I hope you have a VHF and a CellPhone with you :)
