英文簡介

A long standing problem for sailors has been how to contend with the wear and tear of sails when exposed to contact with spars and rigging.
Another problem is that the foot of the genoa often gets caught on the lifeline stanchions and has to be lifted. This brings about a shortened lifespan of the sails as well as an increased risk of tear.
We now present an inexpensive patented product: SAILGUARD – the wheel which facilitates tacking and protects the sails!
SAILGUARD is a split plastic wheel which allows it to be fitted on the lifelines, shrouds, stays and other parts of the rigging without removing the wire and may be snapped closed to ensure the wheel remains in place.
The centre hole is 6,5 mm and can be widened by boring up to 9 mm when necessary.
SAILGUARD allows the sails to ride over and beyond obstructions by its rolling action. The wear and tear when tacking is thereby reduced and SAILGUARD clearly protects the sails in an ingeniously simple way.
