The
deadeyes are spliced round and covered the same as at the masthead. The
lanyards are of local polypro until I can get some good 8 mil; I misread
the plans and thought the lanyards were 10 mil but only the headstay and
bridle lashings are. Builders may want to confirm the length of the
forward mainmast stays with JWD - they were at deck level when the mast
was stepped and we cut about 60 cm off and had to re-splice. They are
still too long but I didn't have the heart to ask the boys to do it
again... |

The
headstay and bridle fittings are made from welded and galvanized steel in
the shape of a pyramidal socket which is filled with molten zinc after the
wire is inserted and splayed. This one isn't painted because after the
mast was stepped it almost touched the bowsprit and was impossible to
tension. We cut about 40 cm off and had to re-pour a new fitting on the
deck at the shipyard! I elected to go with a hanked on jib so the length
wasn't critical. The bridle lashings go around the bow which seems
vulnerable to collision damage. |

We
turned the center deck seats into fuel lockers. I can store seven 5 gallon
fuel jugs on each side with room to spare, to supplement the 6 gallon main
tanks in the engine compartments. This is a good spot to store heavy
loads. The Clements (Tiki 46 #1) have told me that they made a similar
modification to store their fresh water here, and will gravity feed. |

The
ramp in the plan is a bit flimsy in the aft middle. The ramp I designed is
stronger and lighter. The aft "dock" is a triangular section box
spar that is very strong and provides about 90 kilos of gross flotation as
well. Steps go down both sides and chocks are fitted which firmly seat the
RIB in a self draining position. The 3 part lifting tackle shown in the
plan is totally inadequate unless you are Mr. Universe. I fitted a four
part tackle that is still inadequate so I will run it through a turning
block to the mainsheet winch. |

The
other drawback of the plan ramp is that if you actually want to put a
dinghy on it there is the potential for interference with the tiller bar
and the mainsheet. This side view shows my 9' RIB in the raised position
with the rudder at 40 deg deflection. Notice how the sheet just gets
between the RIB and the tiller bar which moves down and aft. This problem
was dealt with by the ramp design as well as making the lugs droop down so
that the hinge rod is even with the bottom of the beam. BTW all the beam
lugs on the boat were through bolted with silicon bronze rather than the
lag screws shown on the plan. Note the step to help get over the tiller
bar and the conduit which will carry the stbd solar panel wires which run
down inside the bimini stanchions. |

Same
view from the cockpit. This design also allows the RIB outboard to be
carried in the down position which is less stressful to the RIB transom
while pitching in heavy (or not so heavy) seas. The steering lines have
not been attached yet. The plans did not include any detail for the
steering line attachment. Also there are no details for running rigging so
don't necessarily copy mine. We used a turning block mounted on a 15 deg
wedge to prevent overrides on the mainsheet winch caused by the upward
angle. Mounting the winch itself this way might work also but if you use
this dumb looking bottom handle winch shown on the plans the handle might
strike the cockpit back. Note the Ariki owned by Tony from New Zealand.
Phuket is becoming Wharram East. |
