Boston Navy Week 2012 kicks off on Thursday. Sure, that means that Charlestown is going to have more than its usual allotment of tourists (and traffic will probably be tough), but it also means that you have the opportunity to check out some cool international ships.

Ships in Charlestown. Full schedule.

Here's what visitors need to know:

• Wear comfortable clothing.
• If you bring a handbag or camera case it will be searched prior to entering. 
• Guests are encouraged to wear flat, rubber soled shoes.  
• Avoid high heels, open toe shoes, necklaces that can get caught on ship equipment and bags that will be too heavy to carry comfortably. 
• Look for clearly marked entrances. 
• Everyone must go through a security check prior to accessing any ship. 
• The security check consists of a walk-through metal detector and/or wand scan. 
• All adults should present a photo I.D. when going through security. 
• Tours are open on a first come-first served basis; no reservation is required or accepted.

From Navy Public Affairs:

"There is no age requirement to tour U.S. Navy Ships during Boston Navy Week. However, there may be steep ladders (stairways) to climb and uneven surfaces to traverse during a ship tour, and thus, tours may not be appropriate for small children and may be difficult for individuals with heart conditions, breathing difficulties, or other medical conditions impacting their ability to navigate such challenges. The ships are not handicapped accessible."

Items not permitted: 

• Glass bottles, cans or containers of any type
• Banners, posters or signs of any type
• Mace, pepper spray, or other defensive sprays or chemicals
• Knives, firearms, fireworks or any explosive; 
• Illegal drugs or paraphernalia
• Flammable liquids or aerosol spray cans
• Club weapons; and animals. 

The U.S. Navy reserves the right to prohibit other items not listed above.
