In the knowledge that Boatshed Gibraltar will shortly be listing two catamarans for sale I thought it would be useful to consider the relative merits of the type.

Choosing between a multihull (such as a catamaran or trimaran) and a monohull yacht involves weighing several factors. Here are some key benefits and potential drawbacks, including less commonly highlighted advantages of multihulls:

Advantages of Multihulls
1. Stability and Comfort: Multihulls offer a much more stable platform due to their wide beam, which significantly reduces rolling motion, providing a more comfortable experience, especially for those prone to seasickness.

2. Shallower Draft: Multihulls typically have a shallower draft than monohulls, allowing them to navigate shallow waters and anchor closer to shore. This is ideal for exploring bays, coves, and other areas that monohulls might find challenging.

3. Speed: Due to their lighter construction and dual hulls, multihulls often achieve higher speeds under sail compared to similar-sized monohulls, particularly in moderate wind conditions.

4. Living Space: The wide beam of a multihull provides significantly more deck and cabin space, making them more spacious and comfortable for long-term living or extended cruising. This also offers privacy with separate hulls housing different cabins.

5. Redundancy: Some catamarans come with dual engines, which provides an added layer of safety. If one engine fails, the second can still power the vessel.

6. Fuel Efficiency: Because of their design and lighter weight, many multihulls are more fuel-efficient under power compared to monohulls of a similar size, especially when powered by dual small engines.

7. Increased Safety: Multihulls are designed to be highly buoyant and are less likely to sink even if one hull becomes compromised. This provides an extra measure of safety in case of a breach or collision.

Disadvantages of Multihulls
1. Initial Cost: Multihulls are generally more expensive to purchase than comparable monohulls due to their complex structure and larger footprint.

2. Marina Costs: Because of their wide beam, multihulls often require more space at marinas, leading to higher docking fees or difficulty finding a suitable berth.

3. Upwind Performance: Monohulls typically perform better when sailing upwind due to their deeper keel. Multihulls may struggle to point as high into the wind, impacting their sailing efficiency in certain conditions.

4. Manoeuverability: The wider beam can make tight marina or harbor maneuvers more challenging compared to the typically more agile monohull.

5. Heavy Weather: While multihulls are generally stable, they can be more vulnerable to capsizing in extreme weather compared to monohulls, which can heel and recover more readily.

6. Storage and Weight Limitations: Multihulls often have less storage space for heavy equipment and supplies, as adding significant weight can affect performance.

7. Heeling Experience: For some sailors, the heeling of a monohull is a key part of the sailing experience, which is largely absent in multihulls due to their stable nature.

Lesser-Known Benefits
- Reduced Noise Levels: The dual hulls tend to isolate noise better, offering a quieter onboard experience, particularly at anchor or when docked.
- Better Ventilation: The wider deck and cabin layout provide more natural ventilation options, which can be crucial in tropical climates.
- Eco-Friendly Options: Multihulls often incorporate solar panels or wind generators more efficiently due to their larger deck space, making them more sustainable for long journeys.

Choosing between a multihull and a monohull depends on the intended use, budget, and personal preferences. Multihulls offer unparalleled comfort and space, making them ideal for cruising and family voyages, while monohulls often appeal to those seeking more traditional sailing performance and cost-effective options.
