Daniel,I'm in the same boat.Wakeboarding is starting to be hard on my old knees.A friend of mine has a foil & is willing to help me get started...but I get the same answer from the war dept. ....."you don't need to spend another $1k on another boat toy!"If you figure out a way,let me know.
She is usually really cool about me buying new toys,but for some reason,she's not with this.I think it's because my friend has been k.o.'d twice on his foil.
