Sails and rigs: sloop, ketch, genoa, gennaker

The rig is the assembly formed by the mast, the wires that hold it up and the sails that drive the boat. The sloop, a single mast carrying a mainsail and one headsail, rigs the vast majority of modern sailboats because it is simple, efficient upwind and easy to handle short-handed. The wardrobe then grows with the programme: a genoa to climb to windward, a gennaker or spinnaker for downwind, a staysail for heavy air.

Sloop, cutter, ketch: the great silhouettes

The sloop dominates outright: two sails, straightforward trim, the best upwind performance. The cutter adds a second headsail, the staysail, set behind the jib: versatility prized by voyaging boats, which shorten sail in stages without changing sails. The ketch carries a smaller second mast, the mizzen, forward of the helm: the sail area splits into smaller sails, each easier to handle on larger boats, at the cost of extra hardware and a little upwind performance. Yawls and schooners remain special cases, beautiful but rare. For a first sailboat, the sloop is a default choice that is hard to argue with; explore the full universe in our sailing yachts family.

The mainsail: the primary engine

Two worlds coexist. The classic battened mainsail slides up the mast and stows in a lazy-bag on the boom: it is the higher-performance option, with real depth in the profile and maximum area, shortened step by step with reefs. In-mast or in-boom furling favours simplicity instead: the sail rolls away in seconds without leaving the cockpit. The price: a flatter profile, often without battens on in-mast systems, so less power, and machinery that must stay perfect — a furler jammed with the sail out in a blow is a genuinely awkward situation. On boats above 45 feet, however, furling systems earn their keep: the sheer weight of a big battened mainsail becomes a real handling problem for a family crew.

Headsails: from genoa to staysail

The genoa is the overlapping headsail that extends aft of the mast: on a furler it can be partially rolled, but loses its shape as you do. Modern designs often prefer a smaller, non-overlapping jib, sometimes self-tacking: it trims itself through every tack, a remarkable comfort when sailing solo. The staysail, a small heavy-cloth sail set close to the mast, takes over when the wind gets serious: it is the sail that turns a gale into merely windy sailing. Many cruising boats rig it on a removable stay. Cloth weight matters as much as cut here: one heavy staysail that keeps its shape at 30 knots is worth two lightweight sails that do not.

Downwind: spinnaker, gennaker, code 0

Off the wind, the wardrobe opens up. The symmetric spinnaker with its pole remains the reference for pure dead-downwind sailing, but demands crew and discipline. The gennaker, or asymmetric spinnaker, tacks down to the bow or a bowsprit and handles almost like a genoa: it has become the natural cruising choice. The code 0, a flat, powerful sail on a furling cable, fills the light-air gap between upwind and downwind angles. A top-down or structured furler — the drum that rolls the sail around its own cable — radically simplifies hoisting and recovery. Snuffers offer a cheaper alternative for asymmetrics: a long fabric sock that swallows the sail as you pull it down over the foredeck.

What a sail wardrobe costs

As orders of magnitude for a 35 to 40-foot sailboat: a dacron cruising mainsail costs 3,000 to 6,000 euros, a genoa 2,500 to 5,000 euros, a gennaker with its furler 3,000 to 6,000 euros. Laminates and membranes, faster and more shape-stable, add 50 to 100% to those figures. A well-kept dacron cruising sail lasts around ten years; laminates age faster. Do not forget the standing rigging: the wires holding the mast are replaced every 10 to 15 years, a bill of several thousand euros that insurers increasingly insist on, covered in detail in our standing rigging guide.

Where to start

No need to dream of a full wardrobe in season one. The sensible method:

• Have a sailmaker inspect the existing mainsail and genoa: UV wear on the leech, clew patches, stitching.
• Prioritise the everyday sails: 90% of your miles happen under mainsail and headsail.
• Add a downwind sail in your second season — a gennaker on a furler for cruising.
• Budget annual care: washing, small repairs, a rig check; a few hundred euros well spent.
• Learn the vocabulary: our glossary illustrates every term, from tack to gooseneck.
• Log your sail hours: knowing a sail's real age in hours, not just years, lets you plan replacements instead of suffering them.

A simple rig with healthy, well-trimmed sails will always outperform a luxurious wardrobe poorly used.
