I always get Dakine XT seat harnesses. I go through them pretty quickly and a break spreader bars even quicker, but they are just right for the sailing I do - lots of support and a high hook height. Now I see that new XT's are very expensive and don't come with a bar. I don't know what that's about but it's a big disincentive to go there again.

What other high-hook supportive seat harnesses are there that I don't have to rob a bank for and actually come with a spreader bar/hook?

Why are you going through them so quickly? mines 8 years old and still going.

Yeah stitch them up.
Do you use the bar to rig?
I broke 2 like that, stopped then never broken one again.

I am a big fan of the XT seat
This is what they look like after around 8,000ks
I just ordered a new one from SHQ without the hook for $214 delivered, I think that's a fair price

I use the Severne Pod and haven't had any issue with it. I was using the Dakine XT before that (I still have it but the hook is in the middle of the bay).
The Severne Pod has less padding but it fits me really well.
Harness are like pairs of shoes though, better to try them on first if you can.

Bars aren't born equal I think. I inherited a bar from an old harness which did have a rust dot on one of the welds. Hasn't moved in years while my other two cracked around the welds.

Unlike 99% of windsurfers if your one of the weirdos like me that sails hook up, be careful what you get if you want to turn the spreader bar upside down!!!

My Severne POD has out lasted all my other kit. Guessing 6years and just a bit faded.

When using seat harnesses, do you rig your boom lower? Do you use longer harness lines with a seat harness and if so, how much longer?

I have both a waist harness and a seat harness. I find the seat harness (Dakine) much more comfortable with no back pain but hooking in seems problematic. I picked up some adjustable harness lines but the stiff plastic that covers the harness line doesn't drop so part of the harness line ends up pointing towards one end of the boom keeping it out of reach for hooking in. Because of this I often find myself going back to my waist harness which gives me a sore back.

Recently I ordered the Liberty hybrid harness which they claim has the hook higher. I hope that helps but dang, it's not cheap.
