Costs & decisions

How to choose a trustworthy marine mechanic or boatyard (and avoid nasty surprises)

Updated: 6 min readCaranva Boats

Quick answer

To choose a good marine professional, always ask for a written itemised quote, check they are registered and carry liability insurance, look for genuine reviews from other owners, ask about experience with your boat and engine type, and avoid paying everything upfront: ideally use protected payment released when you confirm the job.

The 7 questions to ask

  1. Can you send a written, itemised quote (labour, parts, call-out, haul-out)?
  2. Are you registered and will you invoice me? No invoice, no warranty.
  3. Do you have liability insurance? Essential for anyone working on your boat.
  4. Have you worked on my engine brand / boat type? An outboard specialist is not a diesel inboard specialist.
  5. How long will it take and when can you start? Ask for firm dates.
  6. What warranty do you give on work and parts?
  7. Can I talk to a client or see reviews?

How to compare quotes

  • Compare like for like: a cheap quote may exclude the haul-out, parts or VAT.
  • Be wary of prices far below the rest: something is usually missing.
  • Value communication: whoever answers quickly and explains clearly before being paid usually does so afterwards too.
  • Ask what happens with surprises: will they check with you before continuing?

Red flags

  • Cash only or full payment upfront.
  • No written quote or invoice.
  • Impossible deadlines or diagnosis without seeing the boat.
  • No verifiable reviews or references.
  • Price changes at the end without warning.

Protect your payment

The safest option is protected payment: money is held and released when you confirm the job is done. That is how Caranva Boats works, and professionals are vetted and reviewed by other owners. If there is a problem, you can open a dispute and we mediate.

Where to find vetted professionals

Search by specialty and port: mechanics, outboards, electrics, carpentry and teak or all maintenance services by port. Before requesting, check the maintenance calendar to group jobs and save.

Frequently asked questions

Should I pay a marine mechanic upfront?

At most a deposit for expensive parts. Pay on completion or use a protected payment system that holds the money until you confirm the work.

What if the work is badly done?

Complain in writing with photos and the invoice. If you booked through Caranva Boats, open a dispute from the request chat: payment stays held while we mediate.
