HADRON H2 Owner’s Manual 2018

d. Lift the mast to a nearly upright position and place the foot in the mast step.
Ensuring that the boat is in ’bow down’ position will facilitate the lift.
e. Pull the forestay forward and attach it to the shackle on the forestay adjuster
line.
f. Tighten the forestay control line to achieve the required rig tension. Check
that the rake of the mast is appropriate for the anticipated wind strength and
adjust the rake if necessary, using the vernier adjusters on the shrouds.
2. Rig the mainsheet: ensure that the control line tails are positioned forward of the
mainsheet strop or hoop. Pass the mainsheet through the swivel jammer cleat, then the
ratchet block (ensuring the correct direction by checking that the ratchet does not ’click’
when passing the rope through). Then pass the rope through the aft boom block (from
aft to forward), rope strop block (from aft to forward), forward boom block (from forward
to aft) and finally tie it off with a bowline through the strop block.
If sailing in light airs, the 4:1 purchase thus produced can be reduced to 3:1 (and thus
improve response and reduce friction) by untying the bowline and retying it on the
forward boom block.
Tie a knot in the aft part of the mainsheet to ensure that the boom can only just touch
the shroud if the sheet is dropped.
3. Position the boat so that it is head to wind. Ensure that the mainsheet, kicker,
cunningham and clew outhaul control lines are loose and not cleated. Attach the main
halyard to the head of the sail. Feed the sail luff bolt rope into the mast track and hoist
the sail to within about 500mm of the top. Jamb the halyard in the Clamcleat which is
positioned on the front of the mast near the mast foot.
4. Fit the clew band of the sail over the outboard end of the boom. Pass the clew
outhaul line through the starboard side of the clew cringle and slip the end knot over
the groove in the boom end fitting.
5. Lead the Cunningham line through the Cunningham cringle on the sail luff. (This
cringle is situated about 150mm above the tack cringle). Pass the loop in the end of the
Cunningham line over the shoulder of the gooseneck pin and insert the gooseneck pin
into the boom socket. Attach the kicker shackle to the boom strap.
6. Pull the sail to the top of the mast and ensure that the copper ferrule on the wire
strop at the top of the halyard engages in the masthead vee cleat (other methods of
securing the halyard may apply to your H2, such as a lateral Clamcleat). Cleat the
halyard tail loosely in the clamcleat at the mast base. Coil up the tail and stuff it into the
inboard end of the boom or in a halyard bag (if fitted).
7. Secure the tack cringle to the mast using the ’loop and ball’ provided.
8. Tie the tail of the clew outhaul line onto the single block on the clew outhaul tackle.
9. Fit the rudder onto its transom fittings. Ensure that the rudder retaining clip is in
place. Tighten the wing nut on the rudder pivot just sufficiently to keep the blade in a
horizontal position. Lead the rudder lowering line though the Clamcleat on the forward
end of the tiller.
10. Cleat the control lines for kicker, Cunningham and clew outhaul. Adjust the clew
outhaul to the desired foot draft. Take out the slack in the kicker and Cunningham lines
but do not tension at this stage.
The boat is now ready to launch. Note that the Hadron H2 is much lighter than most
boats of its size and therefore great care should be taken, once the sail is hoisted, to
ensure that when ashore the boat is kept head to wind and tied to its trolley. In stronger
winds, if the boat is to be left unattended it should be anchored to a fixed point.
