Catamarans vs Monohulls is a huge debate among sailors. As the name indicates, monohulls are boats that have a single hull. If you have read very far in this website, you know my opinion. But lets dive in and cover these points one by one: Which One Is Safer, and Which One Is Faster?
Catamarans vs Monohulls? Catamarans wide base makes them more faster, stable, safer. Every year more choose a cat even tho they cost more. The original design was monohulls until catamarans, with two hulls, became popular. Because catamarans also have a sail, and are technically also sailboats, the term “monohull” is used to refer to the single hulled sailboats.
Multihulls are sailing vessels that have two or more hulls. Catamarans have two hulls and are a part of the multi-hull family. Depending on what you want from your sailboat, you are inevitably going to have to decide as to what type of boat you want. When you are looking for a sailboat, you have some of options.
For the sake of simplicity, there are monohull (“sailboat”) or a catamaran (multi-hull) or a trimaran (three hulled) boats. I’m only going to be comparing the monohulls and the catamarans. Trihulls, pontoon boats, house boats and other designs will be covered in a future article.
In this article, I will compare the speed and safety of Catamarans vs Monohulls.
Catamarans vs Monohulls: Which One is Faster?
The first catamarans got press by winning sailboat races. They won nearly all the races they entered. Cats are faster. That said, the cruising catamarans are designed more for comfort and are considerably slower than their racing cousins.
Catamarans are nearly always faster than monohulls. This is especially true when it comes to downwind runs, reaches, and broad reaches. There are several reasons for this. First is the low water resistance.
Low Water Resistance
Cats have two hulls that are extremely narrow. Each hull is much narrower than half of the monohull they are replacing. As a result, they sit much higher in the water. This is what gives them incredible speed under the same conditions. The catamaran has a horizontal orientation.
Lighter Boats
While it is generally a bigger vessel, this width gives it much more stability. As a rule, catamarans don’t need deep keels or ballast. This makes them much lighter.
In contrast, monohulls have a very wide hull that takes up lots of room in the water. This wide hull has much more difficult to push through water. Monohulls also are a vertical alignment.
Heavy Ballast
The way they counter balance their sails is with a deep keel and lots of ballast. The keel keeps the monohull from leaning over, it also adds water resistance, called “drag”.
Catamarans vs Sailboats: Which one is the Safer?
Catamarans are also much safer and more stable than monohulls and are also easier to control. Their horizontal orientation gives cats an advantage in stability. They are incredibly resistant to tilting, even in high wind. This is due to their broad base. In strong winds, they will slide sideways rather than tilt.
Catamarans are usually faster than monohulls, and two significant factors contribute to this. Per the Sailing Virgins website, these two contributing factors are that monohulls have much heavier keels than catamarans, and catamarans also keep their sails perpendicular to the wind. If your boat is lighter and the sails are in the right position, you can rest assured that it will be fast. In the sections below, I will go into more detail about both the keel and the sails of these vessels as well as why they affect the speed of the boat.
Keels
One reason why most catamarans are faster than monohulls is that they have a much lighter keel than single-hull boats. The keel of the sailboat is a flat wing that sticks into the water below your boat. The primary function of a keel is that it prevents the boat from being tilted by the wind. They are also produced from the same material as your boat.
Light
Wanting to go fast on the water is a thrill that everybody wants to experience. If you want a faster boat, one thing that will slow you down is a weight. A lighter keel is a lighter sailboat, which will give you a significant advantage over monohulls if you speed. If you are considering a catamaran, then you probably do. Having a lighter keel on a catamaran will give you a lighter sailboat that will be faster than a monohull.
Sails
The second reason why catamarans are faster is that they keep their sails perpendicular to the wind. The total function of your sails is to catch the wind, which propels your boat. This makes the position of the sails quite important if you want to be fast. When your sails are perpendicular to the wind, you will be able to catch a substantially larger gust of wind. This makes your boat faster when sailing downwind, going on runs, or for reaches and broad reaches.
Speed
Catamarans are so fast that one of their primary uses is for racing. They also make good cruising vessels, but I know that you want to open it up from time to time. If speed is what you want, then a catamaran would be a perfect fit for what you need. Believe it or not, the size of your sails and how you position them will have a tremendous effect on your ability to go fast. This gives you the thrill of opening it up and practically flying across the water.
Here are the Pros and Cons: Catamarans vs Monohulls
If the safety of you and your passenger’s safety is one of your top concerns about sailing, catamarans are much safer than monohulls. The two reasons why catamarans are safer than monohulls are due to their stability and the fact that they are much easier to control than monohull boats. Catamarans vs Monohulls? Catamarans!
Stability
It’s not a secret that catamarans are more stable than their old-fashioned counterparts. This is due to the wider base of the catamaran, which doesn’t allow as much bobbing as a monohull. The wide base of the cat makes it much harder to sink than a monohull, which is a significant factor for you and all those who are with you on the water. While it does not pertain to safety, another bonus of having a stable boat with a wide base is that it provides much more deck room than a standard monohull.
Seasick
Catamarans vs Monohulls: An added bonus of having a stable boat is that people tend to get seasick far less often. I am sure that this is something anyone can appreciate. Nobody wants to get sick while they are out enjoying a day of fun in the sun. A stable sailboat is also much easier to relax and sleep in because it does not rock as much as vessels with only one hull. Stability is often overlooked but is essential to your sailing experience. When it comes to stability, catamarans are on top.
Control
Catamarans vs Monohulls: Another reason why catamarans are safer than monohulls is that they are easier to control. This is extremely useful if you find yourself in high seas. Being able to have control of your catamaran can be the difference between making it through the rough waters or running the risk of capsizing and sinking. Although nobody likes to mention this possibility, this is a legitimate concern of anyone who is on the water with you.
Conclusions
Catamarans vs Monohulls: If you happen to find yourself in the market for a sailboat, there are a couple of things that can help you decide if a catamaran or a monohull is the right choice for your sailing needs. These two factors are speed and safety.
Speed vs. Safety
As far as speed is concerned, catamarans are usually the faster boats. This is because they have lighter keels than monohulls. They don’t need a ballast and they keep their sails vertical. Due to this, they are faster on a run or a broad reach.
If you are concerned for the safety of your boat, catamarans are much safer than monohulls. They are significantly more stable because of their wider base, made of floating material and therefore harder to sink than monohulls.
They are also easier to control, which can be useful if you encounter rough seas while you are out on the ocean. Now that you know more about the safety and speed of these boats, you can be certain that you are making the right decision to for your needs.
