Built aboard, not in an office

Tools, books and packs

Everything we've made for cruising sailors, in one place. The interactive tools are free and always will be. The books and packs are the work that took months rather than evenings — written aboard our Fusion 40 across four New Zealand–Fiji seasons, and priced so that one of them saving you a single bad decision pays for itself many times over.

The books

Two books, two different jobs. The first one's about actually getting off the dock. The second's about moving around the Pacific once you have.

Cast Off USD $49

What it actually takes to stop talking about crossing an ocean and go. Why people don't leave, what the money really looks like, picking a boat you can afford to leave on, the refit trap, the people problem, the last ninety days, and what a first ocean passage is honestly like. 118 pages.

The Pacific Year USD $49

Planning a South Pacific season: when to go, which way, and where to be when the season turns. The windows north and south, the island legs where the order you do them decides everything, and the cyclone-season call your insurer has probably already made for you. 122 pages.

Both books together

One answers whether and how. The other answers when and which way. Read them in that order and you've got the whole thing covered, from first idea to fourth season.

USD $79 $98

Or take both books and both packs for USD $119 $166.

The working packs

These aren't reading material. They're the printed, ticked-off, taken-to-the-boatyard sheets that live in a folder with a pencil.

The Catamaran Buyer's Pack USD $39

Every checklist we wish we'd had when we were buying: the pre-survey walkthrough that rules out the wrong boats for free, survey day, the sea trial, NZ Cat 1 prep, and the questions that sort honest sellers from storytellers. Comes with the landed-cost worksheet as a working spreadsheet that does the tariff sums for you.

The Offshore Starlink Playbook Free

Worksheets and a plan picker for keeping a boat connected in 2026: Roam, Personal Maritime or Priority, the application checklist, the 12 nm season sequencer, the ocean data cost sheet, and a cut-off day runbook written to be used with no internet, which is the whole point. Rebuilt in September for the Personal Maritime plan, and now free for your email address.

Free interactive tools

No sign-up, no email required, works on a phone at anchor. If one of them saves you a bad night, it's done its job.

The reefing slider FREE

Drag the wind speed and watch the sail plan change — which reef, what headsail, when the code 0 has to come down, and the warning signs you've already left it too late. Then spin the wind-angle dial to see how she should be trimmed at that point of sail, and where the no-go zones are.

Try the reefing slider

Twelve free guides FREE

Catamaran comparisons, buying in New Zealand, timing the passage south, cyclone-season planning and the Starlink rule changes. The guides are how most people find us, and they stay free — the paid work above is what the guides can't be.

The watch builder FREE

Pick the crew and the watch system and see the rota drawn across the clock — then the number nobody works out the night before leaving: how much sleep each person actually banks, and on which night it stops being enough.

Build your watches

The anchor scope calculator FREE

Five to one is not 30 metres of chain. Set the depth, the tide still to come, your bow height and the forecast, and get the rode to lay, the swing circle drawn to scale, and a red flag if you don't carry enough chain for it.

Work out your scope

The survey deal-breaker quiz FREE

Ten questions about the boat you keep going back to look at. Walk away, negotiate, proceed — or not yet. Notice how often the honest answer is “don’t know”, and get the list of what to ask before you make an offer.

Take the quiz

More on the way FREE

Tankage, provisioning and passage-time tools are on the list. If there's a calculation you keep doing on the back of a chart, tell us and we'll look at building it — reader suggestions are how this section grows.

The boat behind all of it

Every tool, book and checklist here comes out of four New Zealand–Fiji seasons aboard Mā Tori, our 2007 Fusion 40 — refitted 2022, NZ Cat 1 certified, and now looking for her next crew. Nothing on this page is theory we read somewhere.
