We sell Sunstream Float Lifts. Please check them out at: http://www.sunstreamcorp.com/FL10014D.htm

“This FloatLift is the same as the FL10014D, except it comes with two small Hydraulic powerpacks mounted on the guide-ons, instead of one larger one.  One box contains the batteries, and the other 2 12V deep cycle batteries.  This configuration can be tied to a dock or mooring…”
