Catamaran or Monohull - Which is Better?


Listen Later

So, you've decided to buy a cruising boat. Congratulations! Which is the best fit for you? A catamaran or a monohull? Here are some thoughts from someone who has cruised on both.

Summary

Which is a better cruising vessel, a catamaran or a monhull? After cruising aboard both a 37-foot monohull and later a 34-foot catamaran, I've seen benefits and drawbacks to each.

For life aboard, a catamaran is more comfortable. Even a shorter cat will feel larger. Beds are more likely to fit standard sizes, and the space can feel light and airy.

However, storage is usually easier on a monohull. They have more built-in storage spaces. In addition, while no boat should be overloaded, catamarans are particularly sensitive to weight. If you fill a cat with too many spares and tools, it will affect performance.

Underway, cats are faster. Without a heavy keel to push through the water, they slip along. However, monohulls tend to point higher when sailing upwind.

A catamaran's shallower draft opens up more anchoring possibilities. With twin engines, it can do some tricky maneuvers. However, with a wider beam and higher windage, close-quarters handling can be challenging.

Monohulls with fin keels are easier to maneuver, while full-keels can be especially fussy backing into a slip.

Catamarans offer tons of space to entertain in the cockpit. But in poor weather, the deeper and more sheltered cockpit of a monohull will feel safer in rough or cold conditions.

Generally, catamarans are easier to board. A monohull with a sugar scoop completes well. But generally, cats are easier.

While the catamaran's two engines offer a backup if one fails, they also require double the maintenance. Their saildrives provide less drag but also require more maintenance.

For people who dislike heeling, a catamaran's stability offers a big selling point. However, the motion is more jerky underway. Different sailors prefer different motions, and you have to experience it to decide for yourself.

With a roomier deck, sail handling tends to be easier on a catamaran. However, the annoying "slapping" sound under the bridge deck can be irritating when the waves hit wrong. It even happens at anchor.

Noise can be another difference. Catamarans can have an annoying slap under the bridge deck when waves hit just right. It can happen even at anchor.

Don't forget to consider righting ability. A monohull will nearly always right itself. A catamaran, while it's less likely to capsize, will not turn itself back up.

Catamaran costs can be higher because of their width. Consider the difficulties of finding a spot in a marina or getting hauled out. Insurance may be more expensive as well.

Extra equipment--davits, windvanes, solar panels-- works better on one or the other. Think about your needs carefully.

Finally, catamarans are nearly always more expensive to buy and maintain.

So, which is better — a catamaran or a monohull?

Catamarans offer space, stability, and a shallow draft. A monohull offers simplicity, sailing performance, and a boat that will right itself if the worst happens. They both have benefits. The choice is up to you.
