Welcome to Ephemerisle! The first-ever floating festival of politics, community and art will be held October 2-4, 2009 in the Sacramento Bay Delta, exact location TBA, but most likely the lagoon inside Headreach Island. Participants will bring their crafts and their ideas to build an eclectic temporary village of boats, rafts, barges, junks, and other floating structures.
Official information lives on ephemerisle.org, such as:

Platform Build List
- Paul Boehm is working on a cheap modular bamboo/plywood/watterbottle platform in San Francisco/Oakland. Cost estimated at 600$ but that's optimistic. We might build more than one if there's enough interest/helpers and we actually manage to pull it off. Contact Paul at email@example.com if you want to help! -> This turned into Apocaisle

- Trea Kines and Kipp McMichael are building Triangisle
Jeff Chan added some notes and expanded the Ephemerisle Houseboat Info into a separate page.
Boats & Platforms
Share your ideas and resources about how to construct floating platforms cheaply, easily, and with sheer joyful madness and exuberance! Note that there is an Ephemerisle Grant Program to subsidize particularly fun, interesting, or creative platforms.
David Normal and April Lelia are building a platform in the form of a Sea Tortoise. Details are here. We have some extra buckets with sealing lids that can be used for buoys if anyone needs them. I think I will need less than 20 and have another 20 extra. contact firstname.lastname@example.org if interested. Buckets are in Stinson Beach.
Patri is going to pick up flotation barrels in Benicia on Thursday or Friday (sep 24th or 25th), if anyone needs him to pick up some for them, email him, patri-at-seasteading-dot-org.
The Apocaisle group is producing an Instructable for low-cost 8x8 floating platform supported on 4 barrels, with design goals of being relatively cheap and easy to assemble from standard hardware store materials, and easy to transport on the roof of a car. See Apocaisle#The Tatami Project.
Matt Bell has a great post on How to build a floating camp platform for 2 for ~$120 (and it fits in a small car) at http://nasu-dengaku.livejournal.com/232520.html
Greg has a post about Boat Building 101 on the Ephemerisle blog: http://ephemerisle.wordpress.com/2009/07/22/boat-building-101/
- The Cal Sailing Club has affordable lessons and equipment use, as well as a free Introductory Sails class.
- There is a SFSeasteadersSailingClub mailing list.
- If you need access to tools and machines, TechShop is a great resource.
- The NIMBY artist space in Oakland is a good place to build things. The Ephemerisle Staff are tentatively planning to have a series of work days there (probably on Saturdays), where people can build their own platforms, help build the central platform, and get advice and assistance from the President of Platforms, Chicken John.
- Thomas Yost has a lot of information regarding kayak construction, including inflatables, on his website.YostWerks
- Crazy wooden hydrothopter on Instructables: The Hydrothopter
Greg has a post about water camping on the cheap on the Ephemerisle blog: http://ephemerisle.wordpress.com/2009/08/03/water-camping-on-the-cheap/
An inflatable whitewater raft or life rafter makes fine private space.
Used boats can be found on Craigslist, prices are extremely low right now due to the recession.
A Paddleboat would be fun for getting around. New they are $300 -$1000, but they regularly come up for sale on Craigslist and eBay. For example, August 17th, PEDAL BOAT - $100 (fremont / union city / newark) - someone should buy this!
Many websites sell inflatable pool and lake toys, like http://www.inflatabletrampolines.com/. Here are some examples:
- Four-person inflatable boat for just $34 at Walmart, good for sleeping in (has sides), although not sure what the inflated dimensions are.
- This inflatable structure provides shelter, looks comfy to sleep in, and could accomodate multiple sleepers.
- 5' x 6.5' for $30
- Coleman Party Island Float 9' diameter, seats 8 people, holds 2000lbs for $60, hole in the middle, but could easily be covered up.
- Lanai Inflatable raft -- looks sturdier than the Coleman island but costs significantly more. video

Art & Activity Ideas
Big Group Activity
It would be neat to have a big group activity/spectacle, like the Burning of the Man. Add your ideas here: EphemerisleGroupActivity
Water Craft / Transport
- Floating framework with a porch swing
- Shoes to Walk On Water - make your own, even High-School kids can do it!
- Stilt paddleboat. Cross between a paddleboat and a super-tall unicycle. Sit way up high, pedal, it turns a paddle on the water. Base is a triangle or rectangle with flotation (plastic barrels or whatever) at the corners. Or just convert an actual plastic paddleboat.
- Make your own paddleboat: A guy in China did it for $20 in materials.
- Water Unicycle (scroll down to #26).
- Build your own human-powered hydrofoil!
- Write a song, 5-minute play, or standup comedy routine about living on the water / seasteading / ephemerisle.
- Join The Rhodium Element as it drops the beats to get you out your land-lubbin seats and on the oceanic dance floor. They'll be spinning -- well, Abletoning -- a seventy-minute set on Friday night of all your favorite psychedelic/big beat/trip hop/prog house/trance/minimal techno/electroclash/house/full on psy/dark psy/future pop/alternative rap electronica. Didn't Emma Goldman say, "If you can't dance, it's not a revolution"?
- Group performance of a cappella version of "I'm on a Boat"?
- See I'm on a Boat for the original Lonely Island music video.
- I'm not much of a "group organizer", but I'd love to see this happen, and am at least willing to print out lyrics for people.
- Contact Jeff Jones if you're interested (jeffljones at gmail), and we can talk about possibly pulling something together.
Finding artistic ways to highlight the rippling of waves
Waves are beautiful and their intersecting rippling motions can be hypnotic, as this post shows. It would be interesting to find ways of highlighting the water's motion at night.
Some ways of doing this:
- Deploy a grid of lights. The lights could be embedded on small buoys that rock as ripples pass through them. They could be connected together into a grid via plastic rods on hooks and swivels) These lights could change color based on the angle of the buoy. How to do that? One option would be to use accelerometers and a microcontroller to control the lights. The downside of this is that it would likely be somewhat time-consuming to build in large quantities.
- Use a backlit lenticular screen. These screens change their color based on the angle you look at them, so it wouldn't be hard at all to create one that does an interesting pattern as the buoy tilts. For this you'd just need a lamp, a cylindrical lens, and a photographic slide. Or perhaps there's already some LED-powered light that is encased in a plastic case that provides a diamond sparkle sort of effect. Then you could waterproof them and string them into a grid. It's the super lazy version.
- The visual effect of the tilt could be increased by putting a long thin (but light!) vertical rod above the buoy. Thus, even a movement of a couple of degrees translates into a big jump at the top of the rod. Then instead of these fancy mechanisms you could put a simple light at the top, perhaps with a simple physical mechanism to cause the light to swing back and forth as the rod swings.
- Put one lamp either close to the surface or underwater and shine light along the surface onto a flat vertical screen a few feet away. The light would nicely ray-trace off the water onto the screen, creating a variety of interesting shapes. It's water shadow puppet theater.
Sea creatures that play with current
Because water has relatively high drag, lots of interesting things could be done with how water affects the motion of flexible objects.
Long glowing tentacles could be created using electroluminescent wire, ropelights, optic fibers, or UV-sensitive string with a UV light shining on it.
These tentacles could be attached in lots of ways. If there's enough current, they could be interesting to look at even while moored to a static platform. Otherwise, it will likely be necessary to create movement. A spinning platform would be fairly easy... then the tentacles could be attached to this platform. If the platform reverses directions randomly, it could be interesting to watch as the effects ripple out to through the tentacles.
Another, probably more fun, possibility would be to attach the tentacles to a remote-control toy boat. The boat could be re-skinned to look like some psychedelic squid, with tentacle attachments in the back. As the squid drove around, its tentacles would follow in interesting ways. It might be possible to put an attachment along or at the end of each tentacle to increase the randomness of its motion. For example, an uneven attachment could provide lift, causing that section of the tentacle to move around.
Update: In case there's any doubt an R/C toy boat would be strong enough to pull a few dozen feet of EL wire... here's one pulling in a fish its size: R/C boat goes fishing
Aquatic erector set
This falls more into the "interactive art" category. Basically, if you find poles of various lengths and construct receptacles for those poles out of foam or other materials, you could have a truly flexible building system. If the receptacles are made out of foam or hollow plastic, they would likely float. This would allow people to easily build a variety of interesting structures on the playa surface. Custom foam parts can be mass produced with expanding 2-part foam mix. Thus stuff is fairly brittle though... it would likely have to be reinforced with something.
Fire dancing on water
So this does go against the "no fire" rule, but perhaps if it was at a safe distance from everything else it would be fine. A line or network of flame could be created along the water using a variety of techniques. For example, a long U-shaped trench mounted along a series of buoys could be filled with liquid fuel (perhaps with Saran Wrap over the top of the trench to minimize spillage until it's time to burn) The fuel could also potentially be held in the trench using absorbent fire poi material. When one end of the trench is lit, the flame rapidly shoots along the lines of the trench until it gets to the other end, perhaps lighting off other (intended) fires along the way.
More dramatically (and possibly a bit more dangerously), a long "sausage" of poster tube material (which can be ordered by the half-mile, is extremely thin, and is airtight) could be filled with propane and then lit. This would be very easy to do and could result in a very interesting (and quite rapid) burst of flame in the shape of your choosing.
Update: Apparently I'm not the first person to think of white gas trenches and propane balloons. A trench *and* propane balloons I haven't seen anyone put propane in long skinny balloons but I'm guessing it's just as likely to work.
Seastead Model Contest Next Year?
In future Ephemerisles it could be good to have an Ephemerisle Contest between seastead models. These models would be large enough to play on, like WaterWalker2. There might be constraints like requiring that the model can be transported by a single pickup truck. Prizes might be in the $500 to $2,000 range. If the location does not have waves, speedboat wakes can be used to test models.
We might record or link to more details of how this all actually happened.

What we learned
What lessons to bring forward? What worked, what didn't, and how to improve that?
- Safety Issues
The health and safety issues at Ephemerisle-09 were legion, but fortunately there were no major injuries. Here are some suggestions to improve safety at future events:
Quick safety briefing during registration and a safety reference sheet for attendees to keep. This should include warnings about the most common dangers such as getting pinched/crushed between boats or platforms and watching your step especially around electrical lines. Also, the use of anything stronger than weed or alcohol should be discouraged, and those used in much greater moderation than at a party on the land.
A more complete medic kit. The priority item to acquire is an Automatic External Defibrillator (AED)- and make sure it has been plugged in and fully charged before the event!
A speedboat fitted for day and night operation should be available at all times for emergency extractions. This should always be docked to the main platform and nothing else should be made up to it.
For reasons of both safety and environmental protection, perhaps some sort of canvass or tarp can be floated around the perimeter of the main platform. This could catch electrical wires, loose building materials, and random debris before it gets in the water.
Lost and Found
Chris Rasch (crasch at gmail.com or call: 650 773 6419):
I lost two black fleece pullovers at ephemerisle. One was labeled Timberland, the other was labeled Patagonia. If anyone happens to have two extras, would you let me know? The last I saw them, they were in one of the dock wheel barrows. Thanks!
- Contact lens solution (safeway brand) - Upright (single cylinder) lens case - Brown knit cap - Blue/green shiny cowboy hat - Altoids tins - Purple iGo travel tube filled with mystery liquid. - Remote control for those floating blinky light / fountain things (I think these are Bo's) - a gray J Crew V-neck sweater - a gray strap of some sort - A big blue flashlight
Light brown slippers, like flip flops, but smooth vinyl. May be Sean Lynch's from when he went in the water to help with the Seadrome model.
