Hello sailing freaks!

Recently, my back had been getting a beating with mattress and harness issues along with frontloop back slaps. Changing the mattress, moving away from Dakine T-Series to the ION Radium and staying sheeted in longer during forwards seem to help quite a bit.

Now I was curious to know whether anyone had thoughts in regards to best-fitting waist harnesses for those who have (or not have) pelvis tilt?

Thanks all and happy sailing Smile !

EDIT:

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 Very Happy !

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.

Manu....anterior pelvic tilt? I can understand how a waist harness aggravates that condition. Several years ago I returned to a seat harness--Dakine Reflex and I love it. There is a limited amount of hook height adjustment, but unless you like your hook near your nipples I think you'll make it work. Give it a try.

Before changing harnesses you will be better served to address the root of the problem which is probably weak/ tight lower back muscles. A lower back stretching/ strengthening routine should fix it. A seat harness puts you into an ideal position to perform pelvic tilt exercises and can help you to relieve that feeling of strain or fatigue while you are sailing. Downside is the extra effort to hook in. If you are in and out of the harness a lot, a waist harness may work better and you will have to rely on the increased strength/ flexibility from your lower back exercises.

There are several seat harnesses on the market that have high hooks, but DaKine doesn't make one, not anymore anyway, they used to have a Surfseat, great harness, I went thru several of them, gotta look elsewhere. I'd post mine from Flying Objects again, but it gets repetitive.

That, or lower the booms and/or use longer lines. There are many ways to make bringing line and hook together as easy or as difficult as desired. The deciding factor may rest in other factors, such as back support, arm length, maneuvering ease, safety, resting boom on board tail, waterstarting leverage, etc.

I've been trying to play with different pelvis angles, footing and sail trim to find a stance that can handle both gusts and lulls. The idea is to let the sail rotate and pivot around the hook while keeping drive onto the board.

When powered with single fin, it's quite easy and natural. When lulls are deep, water state choppy using multifin, it's more challenging.

I really like my ION Radium, it could sit a little lower.

Since I do have lower back issue, I'm always on the look out for best harness for me. Current favorite is dakine c1, it's a hardshell low profile kite harness. I do retrofit it with roller bar, etc.. I can show it you, I'll be in Cabarete for my usual 4th of july trip, arriving in 2 weeks.

This! I started with a waist harness in the early 80's and gave myself a bad back. I switched to a seat harness for everything in 93 and would never go back. I was somewhat incredulous when waist harnesses became fashionable again in the late 00's.
