I am currently looking to buy a Hunter 216 but my concern is with the hydraulic lift and the rudder. The bay where I sailed can be somewhat shallow which was not a problem because I sailed a O'Day Mariner which gave me a draft as little as 10". According to the Hunter manual the draft can be from 1' to 3'8", but can I release the keel to be anywhere in between? Also the rudder is not a kickup rudder so can it be easily pulled up in shallow water? Any overall opinion of the Hunter 216 would also be helpful? thanks.
