• Space. Have you considered space when thinking about chartering a catamaran vs monohull? Whether it is in the cockpit or saloon, which spans over both hulls allowing for a large inside area, or the foredeck which consists of trampolines which are great for sun-tanning and as vantage points for looking out. Catamarans have a larger inside and outside space compared to monohulls.
• Cabins. The Cabins are much more spacious than monohulls. The locker storage stowage space is always much greater than that of a monohull. The greatest advantage is the considerably larger ports (windows). Which when sailing in August not only gives you a great view but comes in super handy to let in the breeze.
• Stability. Catamarans are notoriously more stable than that of their counterpart. This can be beneficial for new or inexperienced sailors who haven’t quite got their sea legs yet or those who are prone to sea-sickness. Due to their two hull design, cats do not heel over more than 5 degrees. This means you don’t have to continuously check that plates are not sliding off the table!
• Draft. Catamaran’s shallow draft (depth of the hull and keel under the water) have some added advantages. This is a particular advantage in areas with reefs as this shallow draft allows you to sail in much more shallow waters than that of a yacht with a keel, thus allowing you to anchor closer to shore.
• Power. Catamarans have twin engines. This, combined with the shallow draft, allows the yacht to cruise at higher speeds whether it’s under sail or using its engines. The two engines also allow for greater maneuverability in confined areas or spaces, great in marinas or when picking up mooring buoys.

As you can see there are many pros to a catamaran vs monohull.
