Common questions
How do I get answers about my own boat?
Upload the manuals for your engine, electronics and gear, or photograph an equipment nameplate and let Bosun find the right documentation. Once your boat has documents attached, ask Bosun a question in plain language and the answer comes back with the source page it came from.
Bosun gave me an answer that looks wrong.
Bosun's answers are generated by AI models and can be incomplete or wrong. Always check the source page shown with the answer. For anything involving gas, electrical, rigging or the safety of the boat, consult a qualified marine technician, surveyor, or the manufacturer's own documentation — see our Terms of Service.
What does the free period include?
New accounts get 14 days with the whole app, with no card and nothing to cancel. When the 14 days end, BosunMarine stays readable: your manuals, boat record and past chats are all still there. A plan brings back questions, uploads and reading new papers. The plans and their prices are on the Pricing page.
How do I manage or cancel my subscription?
If you subscribed on an iPhone or iPad, Apple handles the billing: open Settings on your device, tap your name, then Subscriptions, and choose BosunMarine. You can cancel there at any time, and the subscription runs to the end of the period you have already paid for. If you subscribed on the web, open Subscription in the app's settings to change plan or cancel. Cancel before your plan renews and you won't be charged again. If you're only away for the season, Hibernate keeps your boat for $2.99 a month: you can still read your manuals, boat record and chats, and download everything.
Can I get a refund?
The 14-day free period is for trying BosunMarine first, so we don't refund for a change of mind. If something went wrong (a double charge, or the service didn't work), email support@bosunmarine.app and we'll put it right, and we always refund where the law requires. If you paid through Apple, Apple handles refunds: request one at reportaproblem.apple.com. The full wording is in our Terms of Service.
Is BosunMarine down?
The status page checks the service every time you open it. If it shows a problem, we've been alerted too.
I paid but the app still asks me to subscribe.
Open the subscription screen in the app and tap Restore Purchases. If that doesn't pick it up, email us from the address on your Apple ID and we'll sort it out.
How do I delete my account and my data?
In the app, open Settings and choose Delete account. It permanently removes your documents, chats and everything saved about your boat. If you can no longer sign in, email support@bosunmarine.app and we'll do it for you. Our Privacy Policy explains what is deleted and what we are required to keep.
Who can see the manuals I upload?
Only you. Your boat's documents are yours and are not shared with other accounts. What you send to Bosun is processed by our AI providers to generate an answer; the Privacy Policy lists every provider and what each one receives.
