Does the customer need a license to rent a jet ski?

It depends on the craft's power and the format. To ride solo you usually need at least a navigation license; for powerful craft, a higher qualification. In the guided or 'baptism' format, the customer can ride without a license inside a marked, supervised circuit.

What insurance is mandatory to rent jet skis?

Each craft must have mandatory civil-liability insurance covering damage to third parties. For the business, adding own-damage and activity coverage is recommended.

Where can jet skis navigate?

They can only enter and exit through the authorized channels or marked zones, can't navigate inside bathing areas and must respect the minimum distance from shore and bathers set by local rules. Confirm the exact limits with your Harbour Master.

What if a customer commits an offense with my craft?

Because the craft is registered to your company, many penalties can arrive in your name. A contract that explicitly transfers liability for damage and fines to the renter is key to passing them on.

Do I have to keep a logbook?

Yes, the activity requires documenting rentals. See how in our guide on the jet ski logbook.

What you need to rent jet skis legally

In Spain, jet ski rental (jet skis are considered recreational craft) is regulated by the Directorate-General of the Merchant Marine and supervised by the Harbour Masters, on top of coastal regulations and each region's rules. As an operator you must meet requirements on four fronts: the rider's license, insurance, activity authorizations and documentation.

Craft (jet skis) properly registered and with their inspections up to date.
Mandatory civil-liability insurance for each craft.
Authorization to run the activity and, depending on the area, occupation of public domain.
Valid license or authorization for whoever operates the craft.
Logbook and documentation for each rental.

Licensing: does the customer need one?

It depends on the craft's power and the rental format. Broadly there are three paths:

Navigation license: allows operating limited-power jet skis after a short theory-and-practice course. The usual route for customers who want to ride on their own.
Higher nautical qualification (PNB, PER…): for more powerful craft a higher qualification is required depending on the craft's category.
Guided or 'baptism' format: the customer rides without a license inside a marked circuit under the direct supervision of a qualified instructor. The most common format for tourist rentals.

The classification of craft by power and the qualification required can change; confirm with your Harbour Master which category applies to each model in your fleet.

Company and activity requirements

Beyond the customer, the rental company must be compliant to offer the service.

Registration of the economic activity and the corresponding tax compliance.
Authorization for the rental activity and, if you operate from a beach or maritime-terrestrial public domain, the concession or occupation authorization.
Craft registered in the company's name, with technical inspection in force where applicable.
Safety and rescue means required for the activity.
Instructors with the appropriate qualification for the guided format.

04 / 07

Mandatory insurance

Each jet ski must have mandatory civil-liability insurance covering damage to third parties. For your business it's also wise to have broader coverage.

Mandatory civil liability per craft (damage to third parties).
Own-damage coverage for the craft, with its excess.
Coverage for the activity and instructors in the guided format.

Renting a craft without mandatory insurance in force is a serious offense and, after an accident, can leave you exposed to respond with your own assets.

05 / 07

Navigation zones and distance from shore

Jet skis can't navigate just anywhere. Their use is restricted to protect bathers and the coastline.

Departure and return only through the channels or marked zones set up for it.
No navigating inside bathing areas or closer than the minimum distance from shore set by local rules.
Respect for speed and safety distances to bathers, divers and other vessels.
Daytime navigation and within the limits of the authorization.

06 / 07

Mandatory documentation for each rental

Each rental generates paperwork you must be able to show in an inspection: the customer contract, the safety-briefing statement and the activity logbook.

Keeping this up to date in peak season is where most operators slip, and where it's easiest for a detail to be missing in an inspection.

Solnow generates the contract and invoice when the booking is confirmed and keeps the logbook compliant with the rules, with nothing to fill in by hand.

07 / 07

Penalties for non-compliance

Breaches of navigation and maritime-safety rules can mean significant fines and, in serious cases, immobilization of the craft or loss of the authorization. Navigating out of zone, without insurance or without the proper license are among the most penalized.

Because the craft are registered to your company, many penalties arrive in your name even when the offender is the customer. That's why the contract must explicitly transfer that liability.
