A COMPARISON BETWEEN ROYAL PRINCESS AND AN EQUIVALENT SWATH SHIP

A preliminary design was created for a SWATH vessel intended to carry 1,200 cruise passengers between West Coast North America and the Orient. The arrangement was based on the P&O cruise liner ROYAL PRINCESS and the hull design was based on trends shown in a number of small SWATH ships currently in commercial service. In a comparison between the SWATH design and ROYAL PRINCESS, the SWATH inevitably required more beam and draft and also a greater power for a given speed, making for an increase in construction cost of about 25% as a result of more steel mass and power. The SWATH design was successful, however, in including a greater number of cabins with their own private verandahs, which would result in a revenue increase of about 20%. A SWATH ship is likely to be a more stable platform in a seaway, which would add to the passenger comfort. With an expanding cruise market, prospective operators might be willing to suffer the higher capital cost if a reasonable profit margin could be realized. The SWATH concept could improve standards of accommodation, entertainment and recreational facilities, enticing more people to holidays afloat.
