Wrap Guide
At 3DFurler.com, we believe sailors deserve clarity, not guesswork.
Modern furling
systems should make sail handling simpler, safer, and more predictable—and the
first step is understanding how wind, sail area, and furling technique actually
work together on the water.
Wind Loads

Below is an informational chart representing Wind Speeds and the resulting loads that accompany them.
3DFurler is more than capable of handling Luff Loads far exceeding this chart. The question is are you ready to handle high sheet loads?
From a study of 1226 Sailboat Injuries, 22% were a result of "caught in lines". Sheet load is directly proportional to High Wind loading.
Note that the force is 4 times when the wind is doubled.
Knowing when and how much to Furl (Reef) your sails is critical to safety.
