I don't have any photos and the boat is wrapped. Basically, the PO made a hefty u shaped bracket from aluminum that is about 1/4 in thick and wraps around the mast base. He drilled two holes through the bracket and mast, side to side, so the bracket can be bolted in place. I would not have done that. He used a stout aluminum pole about 1 1/2 in diameter that gets one end bolted inside the open end of the bracket, obviously on front side of mast. The pole is long enough to reach about 4 in short of the forestay. He bolted stout eye bolts near the end of the pole, one on top one on bottom, and had the eye welded closed where it bends around near the base, so it wouldn't unbend. Jib halyard clips to top eye and is adjusted so pole is angled slightly up toward mast head and secured to cleat. He made a 4 to 1 block and tackle, you could use the main sheet. That long line attaches to lower eye bolt on pole and then to extension pole he fitted to trailer and is used to haul up.
Kind of hard to describe baby stays. Basically I made a pair of wood "lifts" that are attached against outside of gunwale on each side directly opposite mast. An eye bolt through bolted through each block of wood (made from 2 by 4's) was made so it is at the same height as mast step. I use a pair of ratchet straps to hold the lift blocks in place, around hull. A stainless wire with eye at either end is attached across deck and shackled to wood block, keeping the tops of the blocks from tilting outward when the straps are tightened down. The eye bolts at top of blocks then anchor stainless wire stays that form a bridle. The tip of the bridle V is pulled up the mast by the main halyard to below the spreaders by wrapping a short length of chain around mast. Obviously the length of each bridle wire has to be such that the wire is as tight as feasible when it is pulled all the way up.
