Location is important, as is the particular boat. On some boats, especially those that provide tanks and weights, one mesh bag for gear is the norm. And you stash that mesh bag under your seat. Other boats have plenty of storage for roller bags, and those are pretty standard.Have been doing shore diving only so far and I stuff everything into the trunk of my car. Been thinking how many bags I need to bring for boat diving.
It looks like I need one mesh bag for all the gears, a dry bag for things I don't want to get wet, and another weight bag just for weights (some boats don't provide free weights)? Three bags seem a lot to carry...What do you guys typically do?
Edit: good point to add my location. Dive in Monterey but vast majority will still be shore diving in the future. Next boat dive in Monterey but most of my future boat dives will be on vacations and I need to fly with my gears.
The boats I dive from when on a trip to Key Largo (tanks and weights provided) are usually of the former type. The dive boats around home, in Southern California, are more of the latter. It's not unusual here at home for several divers to roll up to a dive boat with a large bag for gear, another for their drysuit, two cylinders, a backpack for dry stuff, and a case for their camera rig. Oh, and a weight bag.
Most responses here seem to be based on everyone's personal experience, which likely isn't relevant to the particular boat you'll be diving from. Find out from the specific boat op, or from people you know that have been on the boat you will use, what is normal for that boat. Rule of thumb: bring whatever you need for your diving, but try to be as efficient with it as possible.
(Edit: if you want to mention the name of the boat and/or location, we can probably offer better advice.)
