You're likely interact with your cabin attendant the most during your cruise. While the automatic service charges will cover their basic gratuities, it's generally considered good form to tip them a bit extra for a job well done, especially if you have made any special requests. Should you choose to, for a seven-night cruise, consider tipping about $2 to $3 per person, per day. But to work out why the ship doesn't tip over, we need to think about where exactly these forces are acting. Those points are the center of gravity for the weight, and the center of buoyancy for the buoyancy of the ship. Looking at a cruise ship, there is a large amount of the ship above the water, and a small amount below the water.

However, if either one has provided some extra special service -- like getting you an upgraded table or having a special cake delivered, a tip of $5 to $10 at the time of the service would be appropriate. Wine ordered with meals will generally have a 15% service charge automatically applied. If the service has been exceptional, consider a tip of $10 to $15 at the end of your cruise. The baggage handlers who take your bags upon arrival at the port don't typically work for the cruise line and therefore won't share in the onboard tip pool. Consider treating them as you would a bellman at a hotel -- a customary $1 or $2 per bag will do. When your cruise concludes, if the port workers aid in getting your bags to your car or a taxi, the same amount would be courteous.
Cruise Ship Nearly Tipping Over
Most people are familiar with the incident in January 2012 just off the coast of Italy. This unfortunate incident involved an Italian cruise ship called the Costa Concordia. This blog helps over a million people to plan their cruises each month. As the rogue wave hit, it smashed windows on the bridge, which shorted out the ship’s navigational systems, and two of the main engines died.

I'm not Shure if they're used on giant cruise ships or not but, gyros are one way of providing stability, and safety. So, even though there might be some risks today’s cruise ships are much safer because of advanced engineering and strict safety rules. The Free Surface Effect poses a challenge to cruise ship stability, as it involves the movement of liquid within the ship. On most large, global cruise lines that’s US dollars, but some of those lines change onboard currencies based on the region they’re sailing. Princess, for example, uses US dollars onboard virtually all sailings—except for a select few departures in Australia, where Australian dollars are the onboard currency.
The most dangerous threat to the stability of a cruise ship is the waves. Despite looking top heavy and like a strong wind would blow it over, most marine experts would say that it’s the waves that are the real threat. Although even the largest of blue whales can weigh up to 200 tonnes, the largest cruise ships can weigh up to 220,000 or more. There have been cases of cruise ships tipping over and even sinking. However, these are due to accidents such as the most recent and well-known modern example of the Costa Concordia, which hit a reef before tipping over. In the event of rough seas or high winds causing the ship to tilt from side to side past its centerline is known as rolling.
Adjusting gratuities
Safe weight distribution is also ensured using sophisticated ballast systems that can take on seawater in various areas of the ship’s hull to immediately even out any imbalance. While highly advanced weather and storm detection systems mean that cruise ships can easily avoid these situations, the fact they can withstand them means the chances of tipping over are very slim. They also must undergo rigorous testing to ensure that the cruise ship is stable enough that it would not tip over in rough seas. These standards and regulations must be met before a cruise ship can ever take on passengers. A cruise vacation can be one of the most relaxing and exciting experiences you ever have had, but you would not be able to enjoy yourself if you constantly worry that the ship might tip over and sink.

Drag is the resistance that the ship encounters as it moves through the water. The ship’s design takes into account the drag and is optimized to minimize it, reducing the impact on the ship’s stability. In addition to helping maintain stability, ballast tanks also play a role in controlling the ship’s speed and fuel efficiency. By adjusting the amount of water in the tanks, the ship’s draft can be changed, which affects the amount of drag and resistance it experiences as it moves through the water.

The event, including some live footage from inside the ship, was also captured and featured in a mini-documentary by the Weather Channel, which can be seen on Youtube here if you’re interested. Having a low center of gravity makes its much more difficult for an object to be tipped over. Crew members also train regularly on what to do in emergencies, including a ship listing. Most cruises sail without incident, but know there’s always a backup plan. These were initially made to correct an unexpectedly high turn rate and address the ship’s tilting. A feature that your average cruiser might not know about, but it can be comforting to someone who may be afraid to try out a cruise for the first time.
Don’t overlook night time excursions.
It's also not advisable to request removal or reduction of the gratuities on principle. The cruise lines have published detailed information on how the gratuities go toward compensation packages for their staff, and train their staff to provide excellent service in any case. SeaDream is a boutique cruise line that operates two small ships. These ships are designed to be as stable as possible, with a low center of gravity and a wide beam. Additionally, crew members must be trained to respond quickly and appropriately to any changes in the ship’s stability, such as rough seas or sudden shifts in weight.
It'll be one less thing on your final bill at the end of the cruise. Still, some critics see the charges as a sneaky way for cruise lines to make their fares appear lower than they really are. In this line of thinking, lines with these charges are essentially breaking out a good chunk of onboard labor costs as a separate line item on your bill. Cruise lines that allow passengers to adjust the amounts downward if they’re dissatisfied with the service will have to make the request to the purser or hotel staff. These cruise lines also add gratuities as a percentage—ranging from 15 to 20 percent—to most specialty dining, bar, and spa charges; those amounts cannot be adjusted. Cruise ships aren’t just impressive vacation spots on water – they’re also marvels of engineering that stay amazingly steady even when the seas get wavy.
This movement can cause the ship to tilt slightly, but the effect is usually negligible. We break down situations when passengers might or might not remove automatic gratuities. You do not need to tip the maitre d', as they are a ship's officer and paid accordingly.
Fortunately, passenger’s vessels are designed to withstand 50-foot waves (15 meters), which are extremely rare. However, huge cruise ships like Royal Caribbean’s Oasis-class ships have four, two on each side. Cruise ships are designed with a U-shaped hull for stability, known as a displacement hull. While the ship in the photo looks top-heavy, cruise ships are incredibly stable. Naval architects take special care to ensure ships remain stable and seaworthy even in bad weather conditions. A cruise ship will not risk itself or its passengers by going into a circumstance where it will tip over.
