PREPARING FOR OFFSHORE CRUISING: SAILS, SYSTEMS, STRATEGY

A practical guide to offshore cruising preparation: What you need to know before you go.

Preparing for, or even dreaming of, embarking on an offshore cruising adventure can seem overwhelming; requiring what feels like an insurmountable mountain of gear, knowledge, and experience. But having returned from their 5,200-mile journey, sailing from New England down to the Caribbean in their boat Althea, Brad and Cara Read say that the secret isn't about having a perfect boat from day one; it's about the process of preparation. Here are some useful pointers from our conversation with Brad:

Buy a Boat and Make Upgrades Where Needed

“Once you've bought a boat, get to know it inside out” says Brad. Before you commit to thousands of miles, you need to understand exactly what you and your boat are capable of. "It's not like we're sailing a Comanche-style race boat and can jump weather systems," Brad explains. "For Althea, that's a steady 7.5 knots. We made sure the boat wasn't limited by anything within our control, so we prioritized great sails, a new steering system, and all-new standing rigging."

But when making upgrades, be strategic – change only the things you can afford and don't do it all at once. "The worst thing you can do is everything at once because that's when people burn out their money and their time," says Brad. "Pick the projects that are vital, achieve those, go out and sail with those new elements to make sure you're comfortable, and then move on to the next."

Build the Right Sail Inventory

You know you need an inventory that can handle the miles, but making the choice can be overwhelming. The good news is you don’t need all the answers before picking up the phone; you need to know what to tell your sailmaker and what questions to ask them. To understand how that conversation would go, we asked Austin Powers, who looks after cruising clients at North Sails, to walk us through it.

1. Start with What Your Sail Maker Needs to Know

A good sailmaker leads with questions, and the more you can answer, the better the recommendation. A handful of things are worth bringing to that first conversation. Start with the boat itself: a heavy displacement bluewater cruiser and a lighter performance cruiser are built to do different things, and they call for different sails; so the make and model matters.

Next, outline where you’re going. “Let the sailmaker know at least your two- or three-year plan,” says Austin. A boat headed for the Bahamas and warmer climates will be specced differently from one bound for New England, an ocean crossing, or a circumnavigation. “Heat has a real say in what your sails should be made of.” Then, how many people will sail the boat. The most common cruising crew is a couple, but a family of four changes the maths; particularly downwind, where extra hands mean more sail options. Additionally, mention your experience and how the boat is set up: in-mast or in-boom furling, or roller-furling headsails all shape the recommendation.

Finally, come armed with measurements. North Sails quotes from a boat’s standard rig dimensions – the I, J, P and E – so having those to hand keeps your quote accurate.

2. Upwind Sails, Choosing the Right Material

Once the sailmaker understands the boat and the plan, the conversation turns to material, and this is where the inventory really takes shape. The North Sails cruising range runs from hard-wearing woven sails to advanced moulded composites.

At the entry point is NPC CROSS-CUT: the most durable and lowest-cost option, with the most stretch of any cruising sail. That makes it a natural fit for coastal sailing, though for offshore work the cloth weight can be increased to build what Austin calls “a really robust, bulletproof cruising sail. You can take it anywhere and get it repaired.”

A step up are the radial sails: Radian, a polyester radial construction, and Radian Ultra, a Spectra-polyester blend. Both suit medium- to heavy-displacement boats heading offshore for more serious bluewater sailing. Crucially, both are woven, making makes them a strong choice for anyone heading somewhere warm. “You don’t run into any heat issues going to the Bahamas or the Caribbean,” says Austin.

In the middle of the range sits NPL TOUR: a mid-priced cruising laminate. It’s a popular choice for mid-displacement boats doing moderate passages.

Then we enter the world of 3Di composites. The polyester-based 3Di OCEAN 330 offers mid-level performance with lower stretch than any woven sail, suiting boats roughly 30 to 45 feet doing coastal passages. Above that, the 3Di OCEAN 370 and 700 lines are built for serious cruising where speed matters as much as endurance: the choice for a performance cruiser that wants both.

3. Downwind, Covering the Angles

Upwind sails are only half an inventory. Downwind sails, the ones that turn a long passage from a slog into an enjoyable journey, come with their own set of questions.

Again, begin with what your sailmaker needs to know. Do you already have a downwind sail, and what is it? What wind angles and speeds are you trying to cover? Austin recommends its easiest to talk in true wind angles and speeds rather than apparent, since cruising boats vary so widely in how fast they sail. How many crew will you have? Do you have a bowsprit, or another way to fly a sail clear of the headstay? And what does the halyard setup look like at the masthead? One question sailors routinely forget: where will the sail live when it isn’t flying? Downwind sails are bulky. “They can take up an entire locker, even fill a whole cabin,” says Austin.

North Sails’ downwind range runs from the deepest running sails to the closest reaching ones. The sail Austin sells more of than any other downwind option is the Helix Furling Gennaker. “The best way to describe it is halfway between a code zero and a downwind gennaker,” he says. It reaches well, runs well, furls neatly and can take a UV cover so it can be left up for long stretches. For a couple covering miles, that versatility is hard to beat.

“One last piece of advice, and it applies whether or not you’re buying new: sails need servicing. They’re just like a car,” says Austin. “A small rip or chafe point left alone becomes a big one. Full-time cruisers should have their sails checked once or twice a year; even seasonal sailors should manage once a season.”

Safety is Non-Negotiable

"Nothing here was skipped. We got our life raft serviced. We had redundant systems. Our headlamps and lifejackets were perfect,” says Brad. "Whether it's RYA or US Sailing, do a sea safety course. Don't even contemplate leaving before you've done that," he emphasised. On board, Brad created a laminated diagram of Althea and posted it on the bulkhead with every critical item colour coded; red for emergency equipment, blue for standard systems, and green for holding tanks. They added rubberised Sea Deck non-skid to the cockpit and upgraded to a super-light aluminium tender, stowed on the foredeck for long passages.

Brad also recommends taking a diesel mechanics course. "It's something I wish I'd done. You need to know how to bleed a fuel line, troubleshoot a battery bank, fix a water pump. Because something is going to break." This is what preparation means; not preventing problems, but having the knowledge, the spares, and the composure to solve them when they arrive.

Plotting a Route

Nothing replaces sitting down with someone who done the journey. "We sat with my then-89-year-old father for three sessions as he went through every nook and cranny of the Bahamas and the Virgin Islands." For those without a network of offshore experts, Brad recommends the Salty Dog Rally: a fleet departure with pre-crossing safety briefings and weather seminars. "There is safety in numbers. It's a great way to make the transition less intimidating."

For planning, Brad suggests PredictWind: a weather routing tool that maps the Gulf Stream and anticipates wind speeds and timing across an entire passage. He also hired Commander's Weather as a secondary check. "Even though I do a lot of my own routing, I wanted someone we actually paid to confirm we were doing the right thing."

And the single most important rule? Never have a deadline. "We never had to pick anyone up at an airport on a specific day. If the weather wasn't right, people waited. We were never going to put the boat or ourselves in danger to meet a schedule."

The Offshore Cruising Kit List

Must haves:

• Predict Wind: weather routing and Gulf Stream mapping.
• Water maker: "Don't go south without one." Brad and Cara used a Spectra Cape Horn Extreme. You can't trust marina water quality in the islands.
• Smart autopilot: modern pilots learn your boat's tendencies and can steer better than any human over long watches. It's also an emergency steering backup.;
• Medical kit: everything from nitroglycerin to splints.
• Spares: beyond belts and filters: water pump impellers, alternator belts, and the exact spare for anything you're relying on.
• Diesel and electrical knowledge: take a course before you go.
• Safety course: RYA or US Sailing. Non-negotiable.

Nice to haves:

• Starlink: for staying connected offshore.
• Paddleboards: for exploring once the anchor is down.

Important to know:

• Insurance: most US companies won't allow you south of Virginia or Bermuda until after November 1st due to hurricane season.
• Customs: the BVIs require in-person check-ins, whereas returning to the US is simplified via an app.
• Anchoring: in the US Virgin Islands, moorings are often mandatory to protect coral. Practise anchoring consistently — a dragging anchor at 2am is no way to spend a night.

Offshore cruising can feel intimidating, but by breaking it down into manageable steps: knowing your boat, building the right sail inventory and prioritizing safety, the horizon becomes much less of a barrier and more of an invitation.
