the main chandlery closed down a couple of years ago, (lamb's), but if you are in a car then mailspeed marine would be the best place to go, which is in warrington, but if you are arriving by plane or ferry and on foot, then only roberts marine and the powerboat centre as mentioned in earlier posts, they are more suitable for bits and pieces then the normal browsing around, (about 5 minutes in each), but the maritime museum can help the hours pass by. The chart agent is up in the cunard building and thats a nice building to browse...
