Relaxed downwind power

Relaxed downwind power

Developed especially for cruising couples and short-handed crews, the Parasailor is easy to handle and well tempered. After all, what you want is a relaxed and drama-free atmosphere on board. Even more so when it's only your spouse and you.

No pole required

Going downwind using a Parasailor without a spinnaker pole

There are several ways of rigging the Parasailor. While it is perfectly fine to use the spinnaker pole just like with a regular spinnaker, it is not necessary to do that. The spreading moment of the wing suffices to con­ve­niently use the Parasailor without a pole.

Good from 70° to 180° AWA

Two sails in one! The Parasailor works from 70° to 180° apparent wind angle (AWA), that is, its covers the domains of both symmetric and asymmetric spinnakers taken together.

Works well on autopilot

A match made in heaven: the Parasailor on autopilot.

A match made in heaven: the Parasailor on autopilot. It's great to see how well they go together. The Parasailor, on the one hand, with its great self-trimming characteristics easily copes with the steering of the autopilot. On the other hand, the autopilot does not have to intervene much, as the Parasailor has almost no tendency to roll.

Training included

Every customer is entitled to a compli­mentary training at our national training center in St. Petersburg, Florida, where we operate a fleet of luxury boats ranging in size from 32 to 50 ft. You simply fly into Tampa airport, receive a complimentary night's stay on one of our boats, followed by a private training session the next day.

At the end of your training session with your private instructor you will be totally confident in your ability to use and enjoy your new Parasailor.

"I'd recommend the Parasailor to everyone"

"You're not at the sheet and guy the whole time, something that really suits a lazy crew. I often set the Parasailor without the pole and just use it like a normal asymmetric. I'd recommend the Parasailor to anyone thinking about buying a new spinnaker."

Jimmy Cornell, sailing pioneer and author, UK

How the wing works

Wing Principle Diagram

A tailwind fills the sail and propels the yacht forward (advance). Part of the pressure escapes through the opening in the sail behind which the wing has been fitted in such a way that the air flows past above and below it. Thanks to the shape of the wing and the angle at which the air flows towards it (with the angle optimised for efficiency), the air on the surface of the wing accelerates faster than the air beneath it. Low pressure then forms on the surface which literally sucks the wing upwards and stabilises it (lift).

The wing lift achieves two essentials effects: Firstly the pressure on the bow is minimised. And secondly the propulsion is increased because the wing's optimised angle of efficiency is designed so that the loss of propulsion caused by the opening is completely compensated for.

Highly durable

Each Parasailor is a highly durable product. Already its structure lets it cope with hard gusts much better than regular spinnakers. The horizontal opening is a true safety vent, allowing a sudden and strong increase in air pressure to exit the sail in a controlled manner. Furthermore, the multi-ply and double-stiched clews as well as the webbing and dacron tape reinforced leeches make the Parasailor a tough downwind sail.

"I had my Parasailor up for more than a week"

"While crossing the Indian Ocean, I had my Parasailor up for more than a week without taking it down. I love my Parasailor and I think it's worth it."

Mike Harker († 2011), hang gliding pioneer and single handed circumnavigator, USA
