Hi. Im looking at buying a boat lift. I have some property on a nice lake 12 miles by 6 miles. I plan to put my boat in the lift and leave it there over the summers. I live about 400 miles away. I need something that is secure (lockable). As I can only be there about 10-14 days a month. The water gets to about 10' at 20' out. The level does not change much. I have looked at hydralic, verticle, and canteliver types. What do you recommend. Please tell me storys about your lift(s) good or bad. Thank You, Steven
