Are you stepping the mast with boat on the trailer backwards? If so what are the advantages to this? My Mystere 6.0 has no pins ("So every body get to hell out of the Way")in the mast base and so I tie it off using a fairlead on the mast near the base to another on the beam centre.Get on the tramp lift and push it upright and get somone to pin it. Now if there was a trailer A' la' tornado cat or Mrarstom I think, that tilted sideways enough to pivot the hulls vertical so you could attach the mast base and then walk mast till it was perpendicular, pin it to the bridle then swing the whole boat mast up, horizontal. Or you could compile all my ideas' on video take them down to parks' and recs' and they will probably be willing to give you mast up storage on a beach all by yourselves.
