I've fished with my spin rod from my kayak for the past number of years, and I always planned to 'graduate' to fly fishing. Well I finally got my first fly rod this Christmas! But I've been thinking that I've never seen anyone flyfish sitting down before. Float tubes are close to the water too but the person is basically in an upright position. I'm just wondering if anyone has any tips on being able to cast while sitting down in a kayak - is it possible? Is there enough height from the water? Will it kill my back? Thanks.
