Ephemerisle Contest

Rafting Problem

A design such that multiple Single Family Seasteads can safely be connected together in the open ocean would be new and unique to seasteading. Joining together in the open ocean is a hard thing regular boats are not designed to do. It is a problem we would like to see solved.

Big Model Contest

Models of about 1:5 scale could be good for a sort of "Ephemerisle" contest. If we could do this in decent weather outside the bay then a full scale seastead should do well on a reasonable migration route. If the models handle 6 foot waves that is simulating 30 feet in full scale.

At 1:5 scale the mass should be 1/125th as much. So if you want to be able to carry 125,000 lbs in the full scale then the model should be able to carry 1,000 lbs. Maybe half that is a more reasonable size, say 500 lbs. So at least 2 people on each seastead model.

Details And Judging

The contest could be to bring 3 nearly identical seastead models that can each carry 500 lbs and float independently with stability better than a 60 foot long 30 foot wide catamaran and then join together. Might say they have to stay together for 2 hours or something. Could also say that 1 pickup truck must be able to carry 1 model. Maybe first do qualifications inside the bay and if anyone looked good there we would then go outside the bay for the real test. We could start at a harbor between Sasilito and the golden gate so it was not far to pull the models to get outside.

The 3 seasteads would each have 2 people on them and long ropes between them at the start. One of the 3 seasteads will have a sea anchor. Then the people on the seasteads have to pull them together and tie things up on their own. Another advantage of this size is that things are small enough this should not be too hard.

The design has to be such that it looks like you could keep connecting more seasteads, not just a solution for 3.

If there were multiple contestants the same year that satisfied this then the most stable one gets the prize. Or maybe you split the prize.

Accelerations can be measured with a $200 "G Data Logger" on both the catamaran and a seastead over at the same time (say 15 minute period) to check that it meets the required stability criteria.

Spectators and Judges

We can charter a catamaran for stability comparison and to carry the judges and spectators. The spectators would pay for tickets to cover the cost. Might even need more than 1 catamaran if we get a good turnout. Can also encourage people to bring their own boats.

The models will be small enough that a regular boat could pull them. No need for propulsion, watermakers, solar panels, or anything else for this contest. Just want to demonstrate stability and joining together. Probably fine to even have 1 boat pull 3 models. Maybe the spectator catamarans can even do this as well.

Prize Amount

I think that $20,000 to $50,000 is probably enough to motivate people to enter this.

Might have a 1:25 scale model contest first to encourage people to check out their ideas. Maybe a $1,000 prize.

Possible in 3 to 8 years

I think something like the WaterWalker could be made to do this. So I think such a prize could be won. It might be a totally different design, just saying I think it is doable. And at 500 lbs payload the models could be built with parts that could fit into a pickup (maybe with one of those racks that let you put long boards over the cab).

Pickup Truck Limit

If people have to be able to fit their 1:5 seastead model on a pickup, then they can't just use some 200 foot barge and call that a model of a 1000 foot platform. This limits the cost of the model, and so the cost of the full scale seastead that it represents. It also makes a more level playing field. We don't want some people making something really massive which competes with others more reasonable scale models. A pickup truck is a size such that people can make the models at home and then bring them to the launch location. To be very specific we should also limit the weight to 2,000 lbs. Also say that while the seastead is loaded on the pickup it must be legal to drive on CA roads.

Watching people put their models together could make for a bit of a "junkyard wars" type entertainment.

It will also keep the scale such that a group can self fund a project and build something interesting, like some Burning Man projects.

Legal Issues

I expect TSI needs to get wavers from everyone who will be on a seastead model. Probably people should only be on them after they are in position. For sure everone should have a lifejacket. But somebody should check with the coast guard about rules for experimental floating structures. Maybe people on seasteads have to wear wetsuits (as well as life jackets) in case they fall in. Maybe we could get a coast guard boat to assist at the event for a reasonable fee. People are allowed to do much more dangerous things than this but there are often many rules that need to be understood and followed.

If legal issues permit I am sure that some spectators would love to spend some time on different seasteads. Probably this can be worked out.

Yearly Contest when Waves Expected

It is easier for judges and spectators if this happens at a known time every year. We would want that time of year to have a good chance of 4 to 8 foot waves outside the SF Bay. The contest would have transportation/assembly/launch done on a Saturday and then early Sunday models would be pulled out of the harbor.

If waves were less than 3 feet or over 10 feet we might have to delay a week.
