I have an 18.5 foot sea ray bow rider and when i drive her i put my knee on the captains chair and stand up while driving. After an hour or so this becomes painful for my knee. Is there something i can replace the captains chair with to rest my knee on or am i better off just getting a taller captains chair and sitting down. If i remove the captains chair just standing up i am too tall to steer comfortably and if i sit down i am too short to see well. Any ideas would be appreciated.
