Pelvis tilt and waist harnesses

[manuel]

How would you say a seat harness helps back issues or more precisely pelvis tilt/low back strain? There may lie the technique to adopt with a waist.

Waist users how do you keep drive into the harness when going over rough terrain? What group muscles come into play?

I feel like for most recreational sailing a waist harness teaches us the right things, promotes good posture. It gives us more range of motion and easier hooking in and out, and finally more room for correction when things get ugly. Only it's a bit more technical, more active.

That's it, I got it. After a nice break, came back and understood how to drive the sail power by sticking my bum out. Shoulders may remain forward towards the sail. My back is completely straight, my abs and legs are taking the load. I may get low to get on a plane and be safer but the main concept is bum out.

This also alleviate any harness riding up issues along with any back stress. Wonderful! Took me about 15 years to learn to use a waist harness, great !

My front arm can push against the boom when well lit up to resist sail flattening and shove more pressure in the harness.

As a result of this new technique, my skills have improved all around, speed, planing threshold and wind range. It's quite spectacular.
