To Roll or not to Roll

This video shows very nicely how a sailboat with double head sails going downwind rolls significantly more than the same boat flying a Parasailor. Recorded on an Amel Super Maramu 2000 during the Atlantic Rally for Cruisers (ARC) 2010. Many thanks to our customer for providing this awesome comparison video.

Parasailing from Tonga to Fiji on catamaran Luna - a Lagoon 380. Look the video and see the Owner demonstrating how easy the Parasailor is.
