Vocabulary related to lugsail of SCAMP

SCAMP is known for its excellent stability and buoyancy. The simple lug rig makes it possible to complete a launch in ten minutes, and recovering should be around as fast too. For a family sailor those are welcome characteristics, as well as the easy handleability for children too. The boat can be stored in a small garage and isn’t too heavy for a small family car to tow.

The boat is designed for home builders primarily. Its building process is very well describled on the manual and the plans. Starting from year 2011 there are over 400 SCAMP plans sold around the world already.

So far the most dauntless sailing trip in a SCAMP took place in Tierra del Fuego where Southern Cross boat had a voyage of several weeks. Tierra del Fuego is where the Pacific and the Atlantic Oceans meet making this region one of the stormiest places on earth. Southern Cross has many customizations to make it suitable to survive in the severe conditions of the area.

It’s essential to keep in mind that despite of her stability also SCAMP can capsize making the whole crew get caught on water. In unfavorable conditions that can expose them to throwning, cold shock and hypothermia. However, good-enough sailing skills, proper gear, proactive weather observing and flexible time schedule help to face these risks confidently.
