See full version: Are Catamarans Stable in Rough Seas
Yes, catamarans are significantly more stable than monohulls due to their twin-hull design more evenly distributing the force of the rough waves slapping on the sides of the boat and the tunnel created to pad the boat with a layer of air surrounding it. Because of this, catamarans more typically offer a smooth ride than monohulls. more
The twin engines that often accompany the twin-hull design of a catamaran also offer increased maneuverability compared to a monohull/singular engine design. While it might not make sense at first to have more than one engine, the dual engine actually gives the sailor more power and ability to navigate the boat. The sailor can use the opposing forces of the engines to get the boat to travel more precisely than using a single-engine. [links]
While monohulls have their advantages, too, the twin-hull of a catamaran simply cannot be beaten in this capacity. The stability that a twin or multi-hull design offers far outranks a monohull which is why the twin-hull is more consistently chosen for this purpose.
Catamarans are a great boat for those who find themselves getting more easily seasick than others. Due to the stability that catamarans provide, most people will be able to enjoy the waves of the water rather than being tossed by them. There are several factors that contribute to the catamaran being better for seasickness than many other boats. here
High-performance cruising cats: High-performance cruising catamarans typically have efficient daggerboards or centerboards, deeper rudders, less windage and less displacement. They can go to windward at a 45-50 degree TWA in nearly all conditions. A performance cruising catamaran can typically outsail even the best keelboats to windward. Given their light weight and ample sail plans, attention must be paid to sail selection to remain safe in all conditions. Strategies for managing storm conditions should focus on higher speeds, lower loads and balance.
Specifically, most cats are happy and safe sailing at 6-7 degrees of heel as measured in flat water, or on the trough of a wave. As the boat approaches 10 degrees of heel, the windward hull will be close to lifting. It is safe to say that a cat should not lift its weather hull while on a cruising passage!
The charter cat: If you have limited sea room, then you need to set up your catamaran to make headway to windward. Most cats built for the charter market have only one headsail, a roller furling genoa, which will be of limited use in storm conditions. On such a boat the heavy weather sailplan may be limited to a reefed mainsail. When sailing under deeply reefed main alone, the traveler should be eased down several feet from centerline to create enough drive to let you make headway. You can monitor your course over ground on the GPS and also use visual bearings (if close to shore) to track your progress.

3. Personal Protective Equipment. Otherwise known as PPE for short, its mandatory equipment that boaters must have onboard or their person. Take a look at the article I wrote about the legal minimum requirements for North American boating. I included a link at the end of this article for your convenience. While you’re at it, read the article about life vests and life jackets, also linked at the end of this article.
It comes down to simple physics. And it’s tough to argue with math. here
Let’s dive into how much more safe the catamaran is than a monohull. We’ll look at what makes the catamaran safer, and we’ll also take a look at what we consider to be rough seas. Then maybe we’ll make a little comparison between the catamaran and a monohull. Moving right along, we’ll start with a quick look at rough seas, so we’re on the same page. That is before I discuss how safe these amazing watercraft are.
Catamarans are safe in rough seas because of more stability, smaller draft, easier maneuverability, higher speed, and less floating so less seasickness in agitated waters. Of course, this is in comparison to a monohull vessel of equivalent length. The more excellent stability is due to a wide stance, double-hull design. The catamaran platform is, by its very nature, a safer and more reliable platform than a monohull ship design. more
2. Local Current Weather Tracking. One of the most important things you can do is educate yourself about the weather. Know what kind of weather is advised and keep on top of knowing as it changes. Knowledge is your best defense against being caught out in rough seas on your catamaran.
One might also say that catamarans are safer due to their decreased fuel requirements compared with monohull vessels. As this is the case, it is much less likely to run out of fuel. It may not be an actual point, comparing physical craft to craft as it has a lot to do with proper planning, and of course, filling up your tank. here
There are several reasons why catamarans are safer than monohulls of equal length. The obvious is that they ride on two hulls instead of one. It would be like skating on two feet instead of just one foot. But, rather than get too deep into a skating analogy (it’s cold outside, so skating was the first thing that came to mind), let’s take a look at the top 6 reasons why I think catamarans are safer than monohull boats of the same length.

There is a big debate about the safety of a monohull versus catamaran when it comes to capsizing. The argument goes as follows. When you capsize a monohull, it is much easier to right the craft again. However, the flip side to this argument is the nearly unsinkable nature of the catamaran. Even if one flips over, due to the nature of having two hulls, it is almost impossible (well, highly unlikely anyway) to sink. So, it may be harder to flip back over once capsized, but I’d take having to wait for help on a flipped deck of a cat than to sink to Davy Jones Locker in my monohull. here
