Requirements to work as a self-employed marine professional in Spain
Quick answer
To work for yourself in the Spanish marine sector you need: tax registration (form 036/037) and social security as autónomo (RETA), an IAE activity code matching your trade, professional liability insurance, the specific qualifications for your trade (for example a professional ticket to skipper, or installer cards for gas and certain electrical work) and authorisation from each marina or yard to work on their premises. You must also invoice every job.
1. Registering as autónomo
- Tax office (Hacienda): census registration (form 036 or 037) with the IAE code for your activity (boat repair, electrical installation, cleaning, maritime transport services…). An accountant will advise the right one; you’ll also find nautical paperwork agencies on Caranva.
- Social security: registration in RETA. Reduced contributions apply for new autónomos in the first months.
- Invoicing: VAT invoice for every job. On Caranva Boats you invoice the client for the full service and we invoice you the commission.
2. Liability insurance
Essential. You work on high-value assets on someone else’s premises; a spark, a dropped tool or a wrong connection can cost a lot. Take out professional liability cover tailored to marine work and keep the certificate: many marinas ask for it before letting you in.
3. Qualifications by trade
| Trade | Usually required |
|---|---|
| Professional skipper | Valid Spanish professional ticket (PPER, Patrón Portuario, Patrón de Litoral, Capitán de Yate profesional…) depending on length and area, often plus basic STCW; foreign commercial tickets may need recognition |
| Marine mechanic | Vocational training in marine mechanics; manufacturer certifications (Volvo Penta, Yanmar, Mercury, Yamaha…) highly valued |
| Marine electrician | Electrical training; knowledge of ISO 13297/10133; installer card for certified 230 V work |
| Gas installer | Mandatory gas installer card |
| Commercial diver (hull cleaning) | Professional diving qualification and medicals |
| Carpentry, cleaning, upholstery, polishing | No mandatory ticket, but training and a portfolio make the difference |
Always check current regulations: they change and vary by region.
4. Marina and yard access
Each marina has its rules: registration as an external contractor, liability insurance, sometimes a fee or percentage, and working hours. Introduce yourself at the marina office with your paperwork; many will add you to their recommended contractors list.
5. Safety and waste
Working at height, confined spaces, chemicals (antifouling, solvents) and hazardous waste (oil, batteries) are part of the job and marinas police it. Use the marina’s waste points.

Frequently asked questions
Can I be paid to skipper with a leisure licence (PER / ICC)?
No. To skipper for payment in Spain you need a professional qualification. Leisure licences do not allow commercial work.
Do I need the marina’s permission to work on a berthed boat?
Generally yes. Most marinas require contractor registration, liability insurance and compliance with their rules. Ask at the marina office before your first job.
