What should I list as included?
Everything a guest would otherwise have to ask about — fuel, rods, tackle, bait, ice, water, and whether food or fish cleaning is part of the price.
The included list is one of the most-read parts of a listing, because it is how guests compare two boats at similar prices. Being explicit wins bookings from operators who were vague.
Do not list something as included and then charge for it at the dock. That is the single fastest way off this site.
