Hi Dave ... We recently updated the Marina pages on BVI Mariner to show Wifi availability based on a request from another TTOL'er ... look under the "Amenities" heading. Nothing currently in the works to provide a Wifi Map, but will add this to the feature request list. My concern with this type of data is keeping it up-to-date (i.e. accurate) as it can be very dynamic and we want to avoid stale data. After users become more accustomed to posting their observations, this type of feature will by more feasible. Thanks for the suggestion. - Mark
