A sailing sloop, with its single mast & two-sail configuration (mainsail & headsail), is a simple & cost-effective rig widely considered a great choice for cruising, particularly for boats under 45 feet.
While more complex rigs like cutters or ketches offer enhanced flexibility for heavy weather, modern advancements in furling systems & sail materials have made sloops more manageable for short-handed cruising. The two main variants are the masthead sloop, prized for its simplicity, & the fractional rig, which offers more precise control over sail shape for performance sailing. The ideal rig for your cruising depends on your boat's size, your sailing style, & your budget.
I’ve had my fair share of time on the water, both racing and cruising and, for me, there’s nothing quite like the feeling of a well-balanced sloop beating to windward. But is the simplicity and performance of a sailing sloop rig the right choice for your cruising adventures? For many, the answer is a resounding "yes."
While racing sailors often favour a high-aspect ratio rig for ultimate windward performance, the needs of a cruiser are different. We need a rig that is manageable, reliable, & versatile across a wide range of conditions, especially when sailing short-handed. This is where a moderate-aspect ratio sloop truly shines, balancing windward ability with ease of handling on all points of sail.
The single mast & dual-sail setup of a sloop is straightforward, but it comes in two primary configurations that are crucial for any potential owner to understand:
This is the simpler of the two designs, with the forestay attached at the very top (the masthead) of the mast. The headsail is the primary engine of the masthead sloop, and its size can vary dramatically. On 'Jalingo II' my old Nicholson 32, for example, I used everything from a small working jib to a large 130% genoa, each suited for different wind conditions, before I saw the light and installed a furling genoa.
A point of clarification: a headsail is called a jib if its clew doesn't extend aft of the mast. If it does, it's a genoa. Knowing this distinction is key to talking to sailmakers!
Modern masthead sloops have often adopted roller furling for the headsail, which greatly simplifies sail handling, especially for a single-handed sailor. However, a major disadvantage is the inefficient shape of a partially furled headsail, which impacts performance, particularly when sailing to windward.
With a fractional rig, the forestay is attached below the top of the mast—typically at 7/8ths or 3/4ths of the way up. This design shifts more of the sail area to the mainsail, which has several benefits:
The main downside to a fractional rig is the complexity of managing running backstays, which are often required to keep the mast properly in column. A small error during a tack or jibe could have serious consequences. I've seen more than one sailor get caught out by this, so good practice is essential.
While the sloop is a fantastic option, it's essential to consider its pros & cons against other popular cruising rigs.
Feature | Sloop Rig | Cutter Rig | Ketch Rig |
---|---|---|---|
Mast & Sail Count | One mast; two sails (main & headsail). | One mast; two headsails (jib & staysail) & one mainsail. | Two masts (main & mizzen); three sails. |
Sail Handling | Simple & easy for small to moderate-sized boats. Sails are larger, making them difficult to manage in heavy weather on larger boats. | Sail area is divided, making sails smaller and easier to handle, especially for short-handed crews. | Sail area is divided into smaller, more manageable sails, ideal for long-distance cruising & older sailors. |
Windward Performance | Generally the fastest to windward. | Good windward performance, especially with the slot created by the staysail. | Less efficient to windward than a sloop; shines on a reach. |
Heavy Weather | Can be challenging on larger boats, as roller-reefing a large genoa is inefficient. | Excellent due to the ability to fly a small, inboard staysail & a reefed main. | Very good, as sail area can be reduced easily with multiple smaller sails. |
Cost & Maintenance | Least expensive to build, rig, & maintain due to fewer parts. | More expensive than a sloop due to an extra headsail, stay, & running rigging. | Most expensive due to the extra mast, boom, sails, & rigging. |

What is the difference between a sloop and a cutter?
A sloop has one mast and a single headsail, while a cutter has one mast but two headsails: a jib and a staysail. Cutters are often preferred for offshore cruising due to easier sail handling in heavy weather.
Are sloops good for single-handed sailing?
Yes, a sloop is an excellent choice for single-handed sailing. Modern sloops with roller furling headsails and in-mast or in-boom furling mainsails are particularly easy to manage from the cockpit.
How does a sloop perform in different wind conditions?
Sloops excel at sailing to windward, especially with a high-aspect ratio rig. While they can lose efficiency off the wind, a moderate cruising rig with a spinnaker or Code 0 sail can provide excellent all-around performance.
What is a double-headed masthead rig (Solent Rig)?
The double-headed masthead, or Solent Rig, is a type of sloop that has two headstays. Unlike a cutter, only one headsail is used at a time, making it a versatile option that allows you to quickly switch between a large genoa for light air and a smaller jib for stronger winds.
