So how do you know what kind of boat you're dealing with? If you want to determine what the rig type of a boat is, you need to look at these three things:
There are basically two ways to rig sails:
A boat with three or more masts that all carry square-rigged sails is called a ship, a tall ship, or a full-rigged ship. So it's at this point that we start calling boats 'ships'. It has nothing to do with size but with the type of rigging.
Single and double reef line setups are a favorite among coastal cruisers and racers. Coastal cruisers love them because no one needs to leave the cockpit if the weather turns for the worse. Racers love them because it allows the crew to work the entire boat from a central location where they can easily hear commands. Blue water cruisers don't seem to favor either of these systems as the added resistance, effort, and spaghetti all lead to more points of failure and instead opt for the lines to be left at the mast where resistance is minimized as are failure points.
The alternative to double reef line setups is a single reef line setup. As you can imagine, it's most appealing feature is that it only requires one line to operate. This makes reefing a sail with multiple reef points less confusing. If you have 3 reef points, you will only have 3 reef lines leading to the cockpit! The lack of cockpit spaghetti will make this setup seem more enticing until you start to look at the problems that come with simplicity. here
Since the reef lines are separate, you are able to properly control the tension in the tack and clew independently. If you feel that the sail is a bit full, you can simply crank harder on the clew reef line to act as an outhaul and pull the sail flatter. more
If you feel that the sail is a bit full and you wish to flatten the sail out, you will need to tension the heck out of the line so that it can pull on the clew enough to produce the desired effect. The clew and the tack share the force. Any effort you put in to the reef line, only half the force reaches the clew as the tack is taking the other half. [links]
The reduced friction directly leads to the reduced resistance in working the sail. Each turn a line makes adds friction to the system. If you want to shake a reef out of a sail, you will need to raise the sail by cranking in on the halyard. In a double reef line setup, the reef lines will twist and turn as they make their way from the cockpit to the mast, but then they will only have 2 major twists after that. A turning block on the boom will send the reef line up, and the cringle in the sail will send the reef line back down. Since the reef line only needs to work its way through one cringle, less line is needed to pass through the cringle to raise the sail and equates to less resistance. more
While it may sound like both of these systems are flawed in dumping all this line in the cockpit and adding a lot of extra resistance to the system, the truth is they do a great job of bringing the lines back to the cockpit. If you do not feel comfortable when you leave your cockpit, then this type of setup would be ideal for you as you would be able to raise, lower, and reef your mainsail all from the cockpit without setting foot on the deck.

Here, notice a small racing dinghy with a sloop rig. This is still a Bermuda rig, but the mainsail is proportionally larger and the jib smaller, for ease of handling and maximum power. Note that the top of the jib rises only a fraction of the distance to the masthead. Such a rig is called a fractional sloop.
A popular rig for midsize cruising boats is the ketch, which is like a sloop with a second, smaller mast set aft called the mizzenmast. The mizzen sail functions much like a second mainsail. A ketch carries about the same total square footage of sail area as a sloop of the equivalent size. here
These tall triangular sails are called the Bermuda rig, or sometimes the Marconi rig, named for their development more than two centuries ago in Bermudan boats. Because of the physics of how force is generated by wind blowing past a sail, tall thin sails generally have more power when the boat is sailing into the wind.
