Free Boat Management Software: What the Free Options Cover and Where They Stop

Start with who will use it, not with the price

The useful question isn't whether a tool is free, but who will be entering data and who will be reading it. A boat looked after by its owner, a boat shared between several people, and boats looked after for paying clients are three different jobs, and free tools are built for the first. Work out which describes you before you compare names:

• One owner, one boat: you log the work and you read the history. A free app or a spreadsheet covers this well.
• Shared ownership, a syndicate or a club: a few people and a handful of boats. Check the user and boat caps, and whether the free terms allow your kind of use.
• A marine business: a management company, a yard, a charter fleet or a crewed yacht. You need staff roles, owner reporting and records of staff time; free tiers built for private owners either aren't licensed for this (Yachtwave's isn't) or aren't designed for it.
• Somebody else's system: if your yard or management company already runs a platform, ask whether owners can use it at no charge before you pay for your own.

Spreadsheets: free, flexible and entirely yours to build

Anyone with a Google Account can use Google Sheets, and Microsoft gives free access to Excel for the web with a Microsoft account, including 5 GB of OneDrive storage. For one boat, a tidy workbook does the job: it opens on a laptop or a phone, you can share it with a co-owner, and there are no plan limits or terms of use to keep an eye on. What it won't do is know anything about boats. Nothing warns you that an impeller change is due unless you build the warning yourself, photos and receipts live in a separate folder, and the record is only as consistent as the least careful person editing it. Our guide to spreadsheets versus software for boat fleets sets out a five-tab layout for a fleet; for a single boat, these are the parts worth setting up on day one:

• A service log with one row per job: date, engine hours, work done, who did it, parts, cost.
• A renewals tab listing every certificate and safety item with its expiry date (flares, extinguishers, liferaft, EPIRB), with conditional formatting that turns a cell amber a month before.
• A 'next service due at' column for each engine, copied from the manufacturer's manual and checked against the hour meter at every reading.
• A shared folder for photos and invoices, with file names that start with the date and the boat's name.
• Version history, which both Google Sheets and Excel for the web keep, so you can recover a row someone overwrote.

Free maintenance apps: what the free tiers include

A maintenance app gives you what a blank spreadsheet doesn't: a structure built around a boat (engines, equipment, documents), reminders, and a history you can open on your phone on the pontoon. Each of the tools below has a free tier and paid upgrades; where they differ is the point at which the free tier stops. Facts checked on each vendor's website or app store listing on 1 October 2026. Plans change, so check again before you commit.

• Yachtwave Personal: $0 for up to 3 boats and 5 crew members, with maintenance tasks and work orders, service history, checklists, basic inventory, documents with expiry alerts, and records you can read offline in the mobile app. It is for personal use only: commercial use (management companies, service yards, charter fleets) needs the Pro or Ultimate plan, at $39 or $49 per boat per month.
• Ready4Sea (made in France, with an English-language app): a maintenance log, a plan of recurring tasks, engine hours, reminders in your own calendar, and the option to invite the professional who services your boat. The free Basic plan covers 1 boat, 2 users, 30 items of equipment and 100 MB of documents. Standard (€29.99 a year incl. VAT) moves to 3 boats and 5 users, with unlimited log export and offline mode; Premium (€59.99 a year, more above 5 boats) lifts the caps.
• Connected-boat apps such as Seanapps, from the Beneteau Group: the app comes from the usual app stores, but it relies on a box fitted on board, sold with a first year of 4G connectivity, after which remote monitoring needs a paid annual subscription. Without it, the maintenance log and documents stay available.

Free tier or free trial? Read the terms before you load your records

A permanent free tier exists to win over private owners. It may exclude commercial use, cap boats or users, and keep reports or bulk exports for paying customers: Yachtwave's free plan, for instance, exports a print-ready record of a vessel, while CSV export from its report builder starts on Pro. That's a business model, not a trick. The risk is building your whole routine on a plan that won't stretch, then typing everything in again somewhere else. A free trial is the opposite: everything unlocked for a few weeks. It's there for testing a tool on your real boats, not for running on indefinitely. Either way, get answers to these questions before your service history goes in:

• Is commercial use allowed on the free plan, or only personal use?
• How many boats, users and documents are included, and what happens the day you go over?
• Can you export the whole history, photos and invoices included, in a format another tool can read (Excel, CSV, PDF)?
• Can you still read your records with no signal, on a mooring or in a shed?
• Does an invited engineer or co-owner see everything, or only what concerns them?
• What happens to your account if the vendor changes its plans? Ready4Sea, for one, launched its Standard and Premium plans in October 2023 and kept a free one.

When free stops working: a worked example

Hypothetical example: a small yacht management business in Palma looks after seven boats for four owners, with two engineers, an office manager and an employed skipper. In a typical week it allocates jobs, watches which engines are close to a service, files invoices against the right boat, reports to each owner without showing them anyone else's boats, and totals the team's hours for the accountant. A maintenance app built for a private owner isn't designed for that, and a free plan licensed for personal use doesn't allow it. A couple sharing one boat, by contrast, may never need more than a free tier. If you recognise more than one of these signs, free tools are costing you more time than they save:

• You keep a second record of boats that already have an owner's app, because you can't see into it.
• Job photos and reports travel by WhatsApp or email, and nobody can find last spring's.
• Reporting to an owner means copying from three places into one email.
• A service or certificate date has already slipped past without anyone being told.
• Timesheets are retyped before they go to the accountant, and every month someone queries a figure.

Where Captain Crews fits

Captain Crews is paid software with no free plan, built for the point where several people work on the same boats. The office, engineers, captains and owners share one record per boat, each with their own permissions: an owner sees only their boats, and job reports only once the office has approved them. Engine hours trigger an alert before each service, the office reaches the team through important notes, everyone gets their own notifications, and staff clock in from their phones, feeding the pay summaries your accountant works from.
