It’s the age-old question for boat lovers everywhere: catamaran or monohull? Both are excellent vessel types but for distinctly different reasons. As some of the world’s top catamaran builders, the team at Circa Marine are breaking down the benefits of choosing a catamaran.
Read on to learn the fundamental differences between these two vessels so you can make the right call when you are choosing a craft to suit your needs.
The answer is hidden in the name ‘monohull’. ‘Mono’, meaning ‘one’, describes a vessel with only one hull, one engine, and one rudder.
On the other hand, catamarans pull double duty with twice the hulls, twice the engines, and twice the rudders. These hulls are bridged by the body of the vessel, providing ample on-deck space.
When it comes to constructing a vessel, there are five vital factors we place above all others. For our purposes today, let’s use those five factors to assess how sailing a catamaran compares to sailing the classic monohull.
Monohulls are well-known for offering the traditional ‘lean’ experience that many sailors enjoy, and they’re often the choice for experienced sailors taking on rough seas. But for every other application, the catamaran cannot be beaten.
As all catamaran builders know, the dual-hull design offers reduced heeling and a smoother ride in choppy waters. On top of that, the distributed weight offers a flat and stable drift while at anchor, reducing rolling motion (and seasickness).
Monohulls tend to be more compact, as they have to fit their cabins into a smaller space. These interiors are smaller and, therefore, easier to heat or cool while out at sea.
That said, if you’re seeking a spacious living area with greater privacy, catamaran builders can provide it. Two hulls make for a lot more space, and the expansive decks will provide plenty of space for lounging or socialising with your passengers.
This also makes catamarans a popular choice for passenger ferries and other commercial applications in which more space is required than a monohull can provide.
Catamaran builders have mastered the art of crafting ships that are faster in light or downwind conditions. Thanks to the aerodynamic nature of the dual-hull silhouette, catamarans have reduced drag and less weight to shift, helping them to move smoothly through the water.
A deeper keel makes monohulls a better choice for upwind sailing, and their agility in challenging conditions makes them a go-to choice for experienced sailors seeking a thrilling experience.
Monohulls have long been the choice for long-distance ocean cruising and rough sea handling, thanks to their structure. A deeper keel provides the additional stability and agility necessary to navigate roiling waves.
If long-distance cruising isn’t on your mind, then the custom catamaran is a better choice. The shallower draft allows you access to shallow bays and closer shore anchorages so you can find the perfect spot to park up and enjoy the view.
Monohulls tend to have fewer systems to maintain, which can make them easier to look after in the long term. They’re also designed to self-right in the unfortunate event that the vessel capsizes, which is a reassuring trait in extreme weather conditions.
But when it comes to safety, there’s almost no comparison: catamarans take the win. The dual engines and rudders provide a built-in backup in case one fails, while the buoyant materials in the hulls ensure these vessels are virtually unsinkable. Even if one of the hulls is breached, the boat will remain afloat.
Finally, how do they feel? Every vessel is unique, and the way your boat’s interior has been constructed will be the most important factor in how comfortable it is to step aboard.
That said, catamarans are prized as the more modern, luxurious choice. The ample deck space ensures you have plenty of room for socialising and relaxation, with a more stable roll that prevents seasickness for those aboard. While traditional sailors might find appeal in the classic, compact design of the monohull, many others would find the look and feel of a catamaran preferable.
Since each type of vessel has its merits, the choice ultimately comes down to what your goals and preferences are as a sailor.
When it comes to the monohull, more traditional sailors or those seeking a classic aesthetic might find their attention drawn there. However, those with a contemporary mindset may choose catamarans thanks to their excellent manoeuvrability, access, and stability.
