Gloves:
I really like the Ronstan Sticky gloves about $25. We have been using them for a couple of years and we both like them the best so far.
Harness:
I make my own based on a design that Metcalf made many years ago. The nice thing is that I do not worry about modifications, small tweeks, because it was my hand that made it in the first place. I admit that I have not used it for 6 days solid like a Tybee, but have many 5-day worlds and nationals events without a care. Custom fits are usually good.
Shoes:
I do not wear shoes, but Eileen likes water aerobic shoes that are like tennis shoes with gummy soles. I think they are Avia, about $60. She sticks very well to the boat.
