Introducing our Bungee 2.0 hydrofoil launching - pulling - towing system. Lot's of fun, and enough towing power to get us all up on a prone foil board, I weigh about 200 pounds and there was enough pull for me to fly. The two big additions to our bungee are the hand crank winch for pulling back the bungee and a quick release attachment.
We used a 16 pound anchor I found on craigslist. Some of the recommendations are at minimum a 25 pound Danforth anchor. Our bungee in this video ended up being 100 feet, we made our own braiding three lengths of 3/8" thick 100 foot bungee cords. We winched the bungee back far enough that the anchor gave way a few times. When it did the anchor would move through the water relatively slowly, maybe 20 feet or so and then settle on the bottom, we still had tension on the bungee but not a very much. Our setup has enough weight to it that there is little chance of the bungee or anchor from flying back towards us, we felt safe even when the bungee was really tight and we could barely crank it back any further.
We also had an inflatable buoy to let us know where the anchor was and hopefully serve as a barrier if the anchor came loose. The other function of the buoy was to keep the bungee up and mostly out of the water. My thinking was that a raised straighter pull would help us lift the foil, whereas a downward underwater pull might make it harder. The buoy also helped other folks on the water see us and our bungee line and go around it. Using a longer rope (100 feet) between our buoy and the anchor helped the anchor stay put, so the anchor had a more horizontal pull rather than being pulled slightly up.
The trickiest part of our first Bungee test was getting up on the board and staying balanced in he first few seconds while launching the bungee. Water starting seemed to difficult, so we set a 2x4 board in between two ladders and used this as our "dock" starting platform. I suspect some kind of floating "dock" would work, maybe an inflatable inter-tube or raft.
One of my motivations for this is to find a human powered affordable way to practice and have fun foil surfing.
These sessions were on a smaller wing (around 120), prior to the winch addition on a bigger wing (160) lift was much easier. So I suspect a bigger wing on this bungee setup would enable some long rides, and give newbies another way to try foiling.
I hope this helps!

A video showing how to setup foil Angle of Attack for surfing, and where I put my feet and why. Since adjusting the angle of attack and being very precise with my feet placement my foil surfing has improved big time. I have much more control and I know how to setup my hydrofoil and foot hooks for the conditions - bigger or smaller waves.
I have been having really long rides and breaching way less since setting up my boards this way. Also getting my cutbacks and bottom turns dialed and pumping more. With this improved control I also feel way more confident in a more crowded surf spot.
I am so stoked on foiling and eagerly looking forward to the next swell!
Here is the shorter version of this how to video:
I hope this helps! Also here is the digital protractor I use in this video to measure the angle of my foil.
I also carve my foot hooks out of this recycled foam. Originally I bought my foot hooks from NSI.

How to setup the Soloshot 3. Below are two videos: 1 - is how to setup, calibrate, and be free of interference.
The second video is how I securely lock my Soloshot 3 and tripod when at the beach, extend the battery life, protect the Soloshot 3 from rain fog wind, and wearing the tag armband.

A tutorial I made for SUP The Mag on how to paddle out through the surf. In this video are a couple techniques I learned this past year, as well as how I get out when it’s overhead plus and heavy.
I am renaming San Francisco Tube City after seeing so many epic barrels this beautiful warm winter day. Twice in the past three years I have wished I brought a prone shortboard with me, a shallow fast reef break in Maui and this day at Ocean Beach.
Driving to the beach I had no idea it would be hollow and barreling. The last time I saw this many barrels it was huge and serious...
