When someone needs a crew member the visit boatcrew.com.au and search for the kind of person they need. They then have to pay to see the contact details. They can pay to view one profile, or buy packs of 10 or more. Or they can pay a flat monthly fee to access the whole data base,
Some example of crew that will be available are deckhands, captains, engineers, stewards, mates etc. A wide range of staff.
The kinds of boats that people will want crew for will range from luxury motor yachts, ferries, super yachts, function boats, tugs, work boats, fishing boats etc.
