The top half of the tops'l is hanked to the leader line with dyneema soft shakles. The lower half of the tops'l is cut back to keep it away from the peak halyard blocks. Rigged properly with a port and starboard downhaul the lower part of the tops'l can be triced over the peak halyard tackle and thus set fair on either tack.
The Dyneema headstay attaches to the mast below the truck with a loup over a hound. The lower end is lashed to the cranse iron with 6 mm dyneema.
The split mast band below the hounds has lugs on the aft side and eye nuts port and starboard. The jib halyard is set on a two part purchase with the upper block on the port aft eye nut and the dead end lashed to the mast band below this one, separating the two parts to keep them from twisting. On the aft side the upper peak halyard block attaches to the 1/2 inch eye with a twisted shackle to orient the block correctly. The port and starboard upper shrouds will pin to the 1/2 inch toggles.
The backstays will be 9 mm Dyneema with line terminators on toggles pined to the band bolts. The lower end of the backstays will attach to a 2:1 whip reeved through a single on top and a single with becket at the deck mounted chain plate. The fall will lead from the lower single direct to the windward jib sheet winch so the runners should not lack for power. The whip will double as one of the two dinghy hoists.
The third split mast band has two lugs one forward and one aft. The aft lug eye is for the double throat halyard block.This upper throat halyard double block ( a single is shown in the photo) is oriented athwartship with the lead off the forward sheave falling to stbd/aft side of mast. The lower throat halyard block is a single with a becket connected direct to the gaff saddle axle that runs athwartship.
The forward lug has two eyes, one for the forestay and one for a single stays'l halyard block. The forestay will have to be measured precisely so I can eliminate the turnbuckle at the gammon iron and therefore allow the stays'l to drop all the way to the deck when doused. There will only be a toggle and thimble at the main deck. Forestay tension will come from the aft lowers and running backstays.
All the halyards and downhauls will terminate at the base of the mast or the pin rails at the gunwales. Only the hauling ends of the backstay tackles will be in reach of the cockpit.
The main sheet will be Harken blocks rove to a four part purchase with a fiddle block on the boom bail, a single with Becket on the traveller car and a single with cam cleat fixed to the center of the taffrail in front of the track. The mainsail outhaul car will run on a Harken track bent to conform to the taffrail curve and capped on each end with a 4 to 1 purchase system to make easy work of hauling the car uphill .
The bowsprit traveler will be on a two part purchase with a bronze cage block at the sprit end. Shrouds will be fastened to chain plates with 5mm Dyneema lashings through Colligo line distributors and terminators.
The mains'l outhaul is on a 2: 1 purchase with a car on a track attached to the bottom of the boom. This 2:1 purchase will be compounded to 8:1 with a 4:1 tackle positioned under the boom close to the mast.
