From a business perspective, I'd favor 3/4 day trips in the morning, 1/2 day in the evening or late afternoon.
Tends to appeal to all types of anglers.
As Steamboat points out, most of the AH fleet in NJ does this and many of these vessels carry well. Same is true for the fleet in Port Jeff. However, Pt. Jeff itself is a day tourist destination and that definitely helps put fares on the boat during the summer season. Not sure if that would work in Queens, but I could definitely see "magic" or "happy hour" trips working out well for people sneaking out of work early who can't do an all night outing.
