I've found that some boats will cause problems if you fill them too fast. A lot of it has to do with the diameter, length and number of bends in the hose from the deck fill to the tank. The fuel and air going in can pressurize the tank just a little faster than the vent can release it. Eventually a big bubble of air pushes back up the fill hose and you get a small eruption. This may happen part-way through fueling, or as soon as you shut off or slow the flow.
You want to experiment the first few times with a high-volume pump until you know how your boat behaves. After the tank is about half-full, I'll stop to "burp" the tank every 10 gallons, reducing that to every 5 or fewer gallons as it gets closer to full. You should be able to tell if any air is released when you stop. If you don't get any blow-back, then keep extending the time between burps. If it never happens, you're good to fuel at full flow. If it does, you've saved yourself some hassle and mess, and possibly paperwork.
