I've got to say I felt more upright and less under the boom with the seat harnessInteresting..I think I tend to sit more in a seat harness especialy when the wind picks up.

.re hooking & unhooking in gusty conditions in chop I think the waist would be easier.Thats the main reason I decided to try one .Ive got adjustable harness lines now so I think that will help in those conditions as Ill just extend them to make the hooking & unhooking easier.
