Laser/ILCA Aluminium Trolley. For many years Optiparts have been the leading manufacturer of aluminium trollies. Now Optiparts have started to produce trollies for a Laser. based upon the same proven quick release system. Made of square Aluminum tube with rounded corners, the frame has welded joints and is anodised to prevent corrosion. The bow locks into a horseshoe shaped padded support. Unlike other manufacturers, Optiparts do not use a webbing sling to support the hull. The hull rests on 2 side supports which lock under the gunwale. In the middle the hull rests on a padded section of the frame. This provides a stable support. Removing the sling decreases the risk of osmosis. Spring locking (Quick release) allows the unit to be disassembled in a matter of seconds for storage and travel. Total weight including wheels: 11.5 kg
