In this arrangement the sprit is used to pole out the clew or clue end
of a triangular sail.
The lateen is another with its sail hung,
fore and aft, from a
However in this case, it is a triangular sail hung from a very
long spar on a short mast.
This has historically been the standard rig for those graceful
Nile Feluccas and Arab Dhows.
The crab claw is a triangular sail on a short mast.
In this case the sailcloth is supported by spars both along
the top and bottom of the sail.
Unlike the lateen where the sail pivots around the mast the
crab claw pivots around the upper leading spar.
Traditionally the spars were curved and the leach concave
hence its similarity in appearance to a crabs claw.
In craft such as a the proa a change in direction requires the
front end of the rig to be moved to the other end of the boat and the
boat to then head in the opposite direction.
A Square Rig has four cornered sails
suspended from the horizontal yards.
The sail is not necessarily square in shape however, the yards
are by definition hung from the middle and at right angles to the
The yards can be ‘braced’ laterally around the mast.
However, most traditional square riggers can only sail six or
seven points from the wind, at best.
and stays would generally prevent the yard being braced up closer than
3 points from the fore and aft line and the wind would have to be at
least a further 3 points aft in order to fill the sail.
once the vessel began to move the apparent wind would begin to move
forward requiring the vessel to bear off by another point or
in use for hundreds of years by western seafarers these sailing rigs
would have to wait for favourable winds before setting off.
vessels with un-stayed masts could get closer to the wind by
effectively turning their ‘square’ sail into a fore and aft Lug Sail.
Gunter is a rig designed more for use on
A gaff supports a triangular sail on a relatively short mast.
The gaff, when hoisted pivots upwards until it is vertical
along side the mast.
This allows for a decent sized sailing rig which can be stowed
