John-
I have a Taipan but the mast/hinge is the same and I have my trailer rigged to raise from the front by myself. IMO much easier than raising from the rear with our mast hinge systems (since if you raise from the front you don't have to rotate the mast). Here's the key "points" (believe me, all learned from trial and error and trying multiple techniques). I also developed this system prior to having a spi on my boat and I don't use no stinking main halyard either so you don't have to rely on any halyards. You can modify this technique if you do have a halyard so you don't need the mainsheet.
Points-
Have your front maststand far enough forward from the front beam that with the mast hinge hooked up the spreader will be behind the maststand cradle. Have your cradle "smooth" so the diamonds will not hang on it when raising/lowering. <img src="http://www.catsailor.com/forums/images/graemlins/shocked.gif" alt="" />
Have your front maststand "extendable" if possible- gives you a "head start" when lifting if by hand and enough angle the mainsheet can lift if desired. Mine extends about 3'. This also allows "finetuning" the trailerable height if, like me, you tow with different vehicles.
Make up two small lines that extend from your trap line wires to the ends of the front beam (these keep the mast centered and prevent falling off to the side since you cannot attach the side shrouds until raised when raising from the front in the middle). I drilled a 1/4" hole in the end of my beams on the top and use SS snap hooks to attach.
I added a "plate" extending off my front beam support just to the side of the mast with a hole I clip my mainsheet blocks into and a plate at the rear mast support that holds a single block with becket. This block has a line ended on it that then runs through a single block that clips to the top block of my mainsheet. This line then runs through the single block with becket and ends in a loop with two SS snap hooks. These attach to the rear shrouds. With the mainsheet fully extended it almost reaches to the rear beam so the line from the rear blocks just reaches the rear shrouds on the mast. It's necessary to have this "2-1" reduction so you don't end up "block-to-block" on the mainsheet before the mast gets upright.
Okay- so now to go through the process-
Pull up to your launch site and make sure there are no overhead wires/branches/etc. in front of you or between you and the water. Undo the front mast strap, hook up the shrouds/trap lines/halyard(s - if removed), lay out trap and shrouds, hook up mainsheet to the front plate, move to rear of boat, unstrap mast, hook up rear blocks to plate and top mainsheet block, push mast forward on tramp, with end laying on tramp in front of rear beam.
Extend front mast support (can alternatively extend once you have it hooked up to hinge). Now just pull mast forward (with the support far enough forward you can do this without having to lift the spreaders over the support- also, with this setup the mast ends up fairly well balanced although it does want to "tip up" a bit when it's all the way forward.
Now hook up the side line extensions from the traps to the front beams, hook up the rear shrouds to the rear line.
Now move to the top of the trailer just forward to the front beam. I hold the mainsheet in one hand and the mast in the other and as I pull on the mainsheet I lift the mast with my other hand. When the mast gets all the way up I just cleat the mainsheet.
Then go unclip one of the side shrouds, and connect, then do the either side, remove trap extensions, mainsheet and rear mast support (leave the blocks on for taking down which is a reverse of the above).
If you have help all you need to do is connect the trap extensions, raise the mast by hand and hold while helper connects shrouds. The extensions double for checking mast rake once the mast is up. <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />
This method is safe and I have raised/dropped the mast by myself in all types of conditions- rainy/windy/gusty under control. I will attach a photo with the mast hooked up ready to be raised.
