Visited with my wife on a wet and windy day which was why we chose it.
The history of the place is great, getting to tour the submarine and other ships was good.
The rope house tour very good and good for the kids as well.
The ticket enables you to visit all year although i wouldn't rush back.
The cafe/restaurant was in my eyes expensive so if you have a family bring your own food and eat in the large mechanics shop which also houses a kids playground.
All in all a good day and a worthwhile place to visit
