9 Safest Catamarans For Cruising, Circumnavigation and Why!

Catamarans (cats) have become sailors’ favorite sea vessels in recent years, thanks to the extra space, comfort, and speed they offer. Additionally, they’ve built a reputation for their unrivaled safety. But which are the safest catamarans on the market?

The safest cruising catamarans offer a good beam to length ratio, sail fast, and are over 42ft. These include the Manta 42, the Lagoon 450F, and the Catana 44. They are stable, waterproof, easy to handle in stormy weather, and feature a sturdy design.

When boarding a boat, you expect to get to your destination safely, and with your bluewater boat intact, this is what cats are made for, but not all cats are created equal. Read on to learn what to consider when assessing a catamaran’s safety and check out my list of the safest cats available!

What Does It Mean To Say a Catamaran Is Safe?

Cruising for weeks on open water comes with several risks, like strong winds, heavy rains, and other potentially dangerous obstacles. Because of that, you need a bluewater boat that’s designed to take a beating from the most demanding conditions because if you compromise your safety, you might end up in a very dire situation with possible deadly outcomes.

What does it mean to say something is safe?

In this context, the word safe means protected from danger, free from harm, or not likely to lose the boat, as well as not likely to cause danger or harm to either personal or cat.

Therefore, when a catamaran is said to be safe, it comes with features that protect you and your crew from danger. As a result, it would be best to consider a catamaran’s safety features before choosing it.

Why do catamarans capsize? Read my article to understand!

Here are some of the factors i (and sailboat engineers i should add) consider to be the most critical when determining a cat’s safety:

Beam to length above 50%

Beam-to-Length Ratio

Although catamarans generally have exceptional stability, this aspect is always relative, as you’ll find some cats more stable in rough seas than others. Therefore, you’ll want to check their beam-to-length ratio. As a general rule, a boat in the 42 to the 48-foot range should have a beam to length ratio of about 50%.

A ratio lower than that can hurt your boat’s stability in heavy winds, but a larger boat can be okay with a lower value. On the other hand, a larger ratio can make sailing more difficult.

Extra HP adds safety

Engine and Powertrain

Catamarans come with twin engines, which is a significant benefit since you can always use one if the other fails. However, a poor choice of engine location can be a safety risk. Generally, a central location distributes the weight evenly, which is better for safety.

On bigger cats, this is not much of a problem since the weight of the engines is only a small fraction of the total weight of the boat. But on smaller and lighter ships, weight location is of greater interest.

Nonetheless, a watertight bulkhead between the main cabin and engine room prevents flooding if the sail drive or shaft gets damaged. 

Having strong engines will also make the boat go faster and offer extra protection from getting stuck in bad weather.

Build Integrity and Quality

Build quality is a critical factor when determining whether a given cat is safe, depending on the nature of your voyages. You’ll want to check the manufacturer’s reputation, the strength and quality of the materials used, and waterproofing features. 

For instance, catamarans made of plywood or cored balsas are could be less safe since they often have maintenance problems once water enters them.

The underwater section of a cat should be solid, impact-resistant, and easy to repair for the boat to be considered safe. A significant portion of the vessel must be made of lightweight fiberglass to prevent the hull from sinking during a collision or capsizing. In other words, you’re safer with your boat upside-down on the water surface than right-side-up but submerged.

Keep the deck clean from obstacles that could trip or injure the crew

Check for Uncluttered and Flat Decks

A cat’s deck is another essential factor to consider when assessing its safety. Generally, uncluttered and flat decks tend to be safer for sailing since the risk of tripping or getting in stuck on something is reduced. Most notably, you should check if your boat comes with an aggressive non-skid surface to prevent slip and fall accidents among your crew. The deck should have robust, quality fittings and large backing plates to distribute heavy loads evenly.

Shrouds and stays should be located so they only minimally interfere with moving about on deck.

Helm Placement and Cockpit Protection

The primary helm station should have an unobstructed view of all four corners of your cat that should be well protected from the elements, like wind and water, and accessible from the cockpit. The idea is to prevent damage to your cat by the weather and prevent flooding, which compromises your safety.

Cockpit Covers

Your cat’s cockpit cover can make or break it under heavy rains. A carefully designed cover protects it from water infiltration when it’s raining and allows for sufficient ventilation. 

Generally, the best cockpit covers come with removable curtains, allow for solar panel mounting, and can collect a significant amount of rainwater, which your crew can drink and use for washing.

Now that you have an idea of the things to consider when evaluating a cat’s safety, chances are you’re thinking of reviewing some of the boats on the market to determine if they’re suitable for your needs. To get you started on finding your dream boat I have put together this list, here are some of the best bluewater boats worth considering:

If you are looking for a specific type of cat i suggest you read on of my other articles such as:

Manta 42

The Manta 42

Arguably, the Manta 42 holds near-iconic status among sailors because it has a solid reputation as a capable, practical long-range sailing bluewater boat. The laminated hull-to-deck joint and collision bulkheads create watertight compartments at the end of each hull, making the multihull flood-proof.

For additional structural integrity, the manufacturer joins the hull and deck using high-grade marine sealants and reinforces it with a 360-degree unidirectional laminate.

Overall, this is an excellent cruising cat. 

It offers an impressive sail-area-to displacement ratio and a pretty decent amount of deck and interior space, and its pushpit contraptions come in handy when you need to secure wind vanes, solar panels, and dinghies. Undoubtedly, this boat offers great performance and stability.

Catana 44

Catana cats prove that the Bali Group means business when it comes to sailors’ safety. These boats are only produced in France, so the company maintains high-quality standards. Aboard Catana, you’ll immediately notice the manufacturer’s efforts to make it safe for cruising.

For instance, this boat’s foam sandwich construction is high density and lightweight, making it unsinkable, resistant to shock and impacts, and rigid. The use of aramid fiber makes this boat even more rigid and resistant to perforation. The helmsman can continue sailing even after impact.

It also comes with crash boxes and waterproof compartments to prevent water entry after a major impact. Arguably, this is a sure-fire way to guarantee buoyancy, making this boat hard to sink!

You can also use the multihull’s daggerboards to tack into strong winds and heavy weather, enabling it to glide over waves instead of capsizing. The high bridge deck clearance is another boost to safety since it prevents waves from reaching the cat’s deck.
