I launch from a trailer at boat ramps every time I sail.
Its no biggie. Find a spot that you can raise the mast and drive the trailer to the ramp with no over head obstructions.
Toss everything you need on the boat prior to driving over to the ramp.
Drop the boat in the water...wade it/paddle it over to a beach area.
Raise sails, and get stuff ready, go sail.
When done, beach it drop sails, go get trailer, put boat on trailer and go park some place to drop the mast. My rig/trailer is parked on the ramp just a couple minutes while I get the boat on/off. Most power boaters are just amazed with the operation and pretty cool. There are always crabby boat ramp people...I usually just laugh at them!
Be carefull of overhead lines and trees while driving the boat around with the mast up!!!!!!!!
This would be a good place for people to put some other tips on trailer sailing. Anything that makes it quicker/simpler/easier to rig/de rig the boat and get it all secured on the trailer!
One I just figured out....weave the standing rigging/trap lines down the tramp lacing...dont have to go crazy. No more trying to coil them up!
Thanks to MMillers hobie rigging video!
