Mark,
I use the exact same system as described by Gary with a very small modification. The boat is very close, ie.1 inch or so behind the trailer and the mast starts on the trailer mast supports. Slide it back enough and push the base down to engage the step and insert pin. This prevents the mast from hitting the self tacker. Whether your trailer has a rear mast support and how high it is will determine if it will work for you. Also if the boat looks like it wants to rollback I tie a line from the bridle fitting on the hull to the trailer. There have been a couple of times with strong winds coming from behind the boat that I have tied the traveller to the main halyard before atachng the side stays to the boat but this is very rare as gravity is usually enough and I remain in front of the front beam and just lean over to attach the stays.
Taking it down is the reverse with the mast coming down into the rear trailer support. Remove the pin and allow the front to go into the front mast support.

Like I said I don't like walking on my boat and it is a bigger step up and down from the back of the Blade than a Taipan. You could solve the step up down thing by having the trailer behind the boat and mast starting in its supports but the mast has to spin through 180 deg once it is up or before it comes down.

It really gets down to whatever you feel the most comfortable with.

Whatever you decide be careful and never rush.

Regards,
Phill

I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!
