Jimmie...There's something to be said about being towed around by a Big Blue...the challenge arrives at the side of the craft with sharp teeth and an attitude. A lipping device helps turn the tide in you favour. Everything not secured by a teather is in peril (sooerorlater).
I don't take the YAK out in terribly open water since I prefer the estuaries, coves, flats, and more user/YAK friendly waters. A long bungee allows me to get out and wade fish while always being "attached". There is a comfortable learning curve and after a short time you'll feel secure (don't forget your float-coat!). The YAK opens up interesting horizons while you get a workout!
