- see the passing screws and the
multiple hole hardware in order to move the sail forward and back
according to wind intensity
w1_boom_end,
W1_sail_base
- see the lines moved to a block
in order to control sail base tension and the control (on ther boom). In
vtr1 the control is moved to the boat
vtr1_centreboard_control
- see the tweo lines looped
together in order to block the centreboard in any position (up or down)

- a general view on the manoeuvres,
note the halyard control in picture 1 and the double pivoting system for
the sail control in picture 2

- how the halyard is moved from
the nose to the base of the mast and after controlled with a 8:1 system on
the left side of the centreboard

centreboard, vang left, sail tension on the gaff, sail tension on the

- in this wood boat (note the
spacers in order to m ove the mast foot forward and backward) form left to
right: vang left, halyard, on the eye downhaul, vang end, centreboard
control, downhaul control, vang right
vtr1_sheet_control,
w1_main_control
- the block for the control of
the main sheet; in the vtr boat is (better) positioned just at the end of
the centreboard
w1_main_sheet
- a correct way to position the
blocks on the boom (the line is vertical referred to blocks on the boat
for less effort and the blocks are attached to the boom in a way to
minimize efforts on the boom
w1_gaff
- on the gaff end a multiple hole
hardware (same as boom) in order to control sail position to accord better
with gaff depending on the gaff curve
w1_gaff_movers
- the two lines to move the gaff
are joined together thru a sandow in order to maintain in position and not
interfere downwind when the boom is full opened
w1_bailer
- in this boat there are two
bailers (one on each side) located in the lowest point near the aft part
of the centreboard case
General
comment
In the
vtr/wood boat (a recent Nauticalodi ITA2176 Blade Runner owner Paolo Corbellini)
(vtr1 pictures) everything is controlled from the boat.
The
downhaul in doubled on both sides thru two clam cleats under the forward seat
and the sheet is ended on the centreboard to adjust the length of the lines
according to boom height
The vang is
controlled thru a pivoting clam cleat on the rudder and one end is also on the
centreboard to permit control from aft with strong winds
On another
pivoting clam cleat are located the controls for the tension on the sail on the
gaff and on the boom (note that tis manoeuvres are easy to put in place on
aluminium rigging. On wood riggings are more complicated (but not impossible to
achieve)
On the left
side of the centreboard is located a 6:1 system to adjust tension of the
halyard who is first secured to a camcleat, the hooked thru a loop to 6:1
system, alsdo on this side the downhaul adjust camcleat
On the
right side of the centreboard the centreboard control lines and the vang end
line.
In the wood
boat (a 25 years old Colombo ITA 1751 Klumsje owner Franco Guidolin) (W1
pictures) downhaul and vang are controlled thru pivoting clam cleats on the
centreboard, the tension of the sail on the boom is controlled thru a mechanism
on the boom and the tension on the gaff is not controlled
