Launch Sites

Ephemerisle is sponsored by The Seasteading Institute (TSI), cheapest
a 501(c)3 non-profit with the mission of furthering the establishment of permanent, discount autonomous ocean communities — seasteads. In opening a new frontier, we will improve the human condition worldwide by enabling innovation with new political and social systems.

We’ve been covered in Wired and The Sunday Times, and in 2008 we received $500,000 of initial funding from Peter Thiel, co-founder of PayPal and early investor in companies such as Facebook and LinkedIn.

TSI is working to make seasteading a reality by working on three different areas of focus:

  • Working on the engineering challenges inherent in living on the sea.
  • Developing business models that would function on seasteads, in order to attract capial investment to the sector.
  • Building a community around seasteading, and increasing awareness of the benefits that a successful seasteading movement would make available to humanity.

Launch Sites

For those of you new to the water, sales a launch is simply a concrete ramp leading from a roadway on land into the water.

Launches can generally accomodate a boat/platform of standard road trailer width (approximately 8′). Larger craft may require special arrangements to get into the water. Contact us at if you need advice.

Paradise Point Marina (Boat rentals only!)

This is where the houseboats (and other craft) are rented from. Paradise Point is about 8 miles from the event site, generic and navigation can be fairly confusing along Disappointment Slough (the route between the marina and Ephemerisle). Paradise Point does have a public boat ramp and a large parking lot, both of which will be very busy on the weekend — don’t count on there being much (any?) space in the parking lot. (The marina operator reports “lines of boats and trailers” waiting to launch.) Last year we used this spot for assembly of platforms etc., and we have been advised that this will NOT be possible for 2010. Except for people renting houseboats, we do NOT recommending using this marina as a primary access point for Ephemerisle 2010.

B&H Marina (Friendly to platform building and launching)

This marina has a large, flat launch area and a great deal of accessible parking. They also have several wide lawn spaces which are used for overflow parking on busy weekends, as well as a storage yard which also has open paved and grassy space. The manager, Candy Kelp, was extremely accommodating about the possibility of having people finish construction of self-built craft at their space — said just to check with her first. We’ve been warned by locals that this marina is heavily used by delta bass fishermen on summer weekends.

  • 15135 W Eight Mile Rd, Stockton, CA 95219-8721
  • (209) 951-4634
  • Launching costs $10. First day’s parking free; $5/extra day.

Korth’s Pirates’ Lair (Close to event, with lots of services)

A happenin’ spot at the tip of Brannan Island, approximately 5 miles from our event site. They have a large parking lot, and a public boat launch that is easily accessible, but fairly steep and narrow, and does require some quick maneuvering once launched. Our guess is that this place will be HOPPING on a summer weekend.

  • 169 W. Brannan Island Road, Delta Loop, CA 95641
  • (916) 777-6464
  • Launching costs $7. First day’s parking free; $4/extra day.

H&H Marina (Closest to event)

This is the closest marina to the event site; less than 3 miles away by water. The marina is for sale and largely shut down, so services are limited. The lot has space for 70 vehicles. Launch ramp is quite narrow (15′ wide) and requires some quick maneuvering after launch. Current marina management said that they were OK with people doing construction in the lot as long as space was available, but weren’t willing to RENT space to us. Note that the parking lot is across the street from the launch ramp and down a somewhat steep hill.

  • 15135 W. Eight Mile Road, Stockton, California 95219
  • 209-951-4634
  • Launching costs $10. First day’s parking free; $5/extra day.
