Does Hull Length Matter? Unveiling the True Size of Boats

When embarking on your next charter or purchase, picking the right boat is essential to ensure your needs are properly met. When faced with the decision between monohull or multihull as you review the extent of options available to you, this article aims to explain the true details of boat size and will help you understand the right boat for you and your needs. It also challenges the idea that longer means more space.

Beyond the Surface: Length vs. Size

The common misconception when comparing boats lies in the emphasis on length alone. While length certainly plays a role in determining a vessel’s stability and speed, it’s crucial to delve deeper into the intricacies of size. Enter the multihull, a revolutionary design that challenges the traditional dominance of monohulls.

The True Measure: Volume, Cabins, Heads

Imagine a catamaran slicing through the water, and you might visualise sleek lines and cutting-edge design. However, the true magic of a multihull lies beneath the surface. Unlike monohulls, which carry their living spaces in a single hull, catamarans spread their accommodations across two hulls, providing a voluminous living area.

To truly understand the size of a boat, one must look beyond its length. Consider the volume within, the cubic feet of space that translate into comfort and freedom. Multihulls boast an expansive volume, offering a surprising amount of living space compared to their monohull counterparts.

Cabins and heads, crucial elements of a comfortable voyage, are where the multihull shines. The dual-hulled design allows for separate cabins on each side, providing privacy and tranquility. Additional heads ensure that personal space is never compromised, making life on a multihull a luxurious and practical experience.

Economics of Space: Getting More for Your Money

In the realm of boating, where space is a coveted commodity, multihulls present an economic advantage. Comparing the cost of a monohull with a similar-length multihull reveals a stark contrast in what you get for your investment. Multihulls deliver more cabins, more heads, and more living space, making them more comparable to a 42footer monoholl, rather than its monohull counterpart with the same 37foot length.

The Multihull Advantage: Stability and Comfort

Beyond the economics of space, multihulls offer inherent stability, a quality that transcends traditional sailing experiences. The wider beam and dual-hulled structure provide unparalleled stability, reducing the rolling motion that can challenge even the most seasoned sailors. This stability extends to the comfort of life on board, ensuring a smoother and more enjoyable journey.

How to Accurately Assess Boat Size

In addition to the prior analysis, it’s crucial to explain how to accurately assess a vessel’s size. Comparing the Length x Beam ratio forms the basis for a reliable comparison. To refine this further, there is a formula that can help understand this: (Length x Beam) x 0.936 for Catamarans and (Length x Beam) x 0.864 for Monohulls.

For instance, applying the formula to a Catamaran with a Length of 44 foot, that has a standard beam of 13ft would yield a more precise volume metric: (43,8 x 13,11) x 0.864 = 496,12 cubic feet.  Comparing this volume to a 37foot multihull that has a Length of 36.5feet and a 15,2ft bean, would result in the following metric: (36.5 x 15,2) x 0.936 = 519,29 cubic feet. By this calculation, it is visible that a multihull with a size of 37 feet yields more volume than a 44ft monohull. This increased volume means you are getting much more space for your money than buying a 37foot monohull, making the space more comparable to a much larger monohull. The hull length should not be primary factor when valuing a boat, as it is not the most accurate depiction of the true volume you are getting when comparing monohulls to multihulls. It is also important to note that the catamaran carries its full beam more forward than a monohull, preventing volume loss in the bows.

Choosing Your Key to Adventure

As the winds of choice fill your sails, consider the true measure of a boat. Length may catch the eye, but size encompasses the essence of comfortable living on the water. In the realm of monohulls versus multihulls, the latter emerges as a clear winner in the battle for space, offering a cost-effective and luxurious solution for those who seek more than a mere vessel — a floating home on the expansive canvas of the open seas.

So, fellow seafarers, as you embark on your quest for the perfect boat, remember: size matters, and the multihull is the key to unlocking a world of spacious, stable, and sensational sailing adventures. Cast off, and may your chosen vessel carry you to horizons as vast as the seas themselves.
