Hello Guys My boat is 2006 Sundancer 260DA. I know this is a common question about the opening the hatch, but my case is very complicated. I hope I can find some answers with a best solution. I left my boat in Long Beach slip for over two weeks, I plug to shore power as usual, but somehow the battery did not charged and drain out. I checked all switches, lighting and all seems fine. I opened the emergency cap under the back seat, reach to the battery, use my battery charger direct to shore power, and bad battery - problem found. so I got a spare battery, use cigarette receptacle to lift up the hatch, only moved up 1 inch then stopped. I am 100% sure not the spare battery or the switch issue, I used multimeter test the spare battery and switch both have 12.5 volts. now the new problem is Hatch hydraulic arm is frozen/broken. because of that 1 inch, arm pin under the emergency cap is stuck, as well as my feeling/mind. now, I have a dead boat on slip with stuck pin and hatch. what i can do to open it? any suggestions? I am thinking to tow to closed the on dock mechanic shop, but I don't know any, anybody can give me a referral? thanks for all reading and happy boating to everyone. I am 4 years old boat owner, still learning every time I use my boat. I have not yet loose my interest to own a boat, but not too far.
