Here are a few things to consider when renting a catamaran:

1. Determine your experience level: It is important to determine your experience level when renting a catamaran. If you are new to catamaran sailing, it may be more appropriate to start with a smaller catamaran or go on a charter catamaran with a professional captain.
2. Learn about routes: Before renting a catamaran, learn about cruise routes. This may include information about which routes are safe, which routes are more challenging, and to help you plan your route.
3. Watch the weather conditions: Weather conditions are of great importance when you are at sea with the catamaran you rent. In the case of adverse weather conditions, it is important to shore the catamaran or find safe shelter.
4. Pay attention to the technical details: It is important to pay attention to the technical details of the catamaran you will rent. In particular, pay attention to whether the safety equipment (life jacket, life buoy, lifeboat, fire extinguisher, etc.) is complete.
5. Insurance and catamaran charter contract: Make sure the catamaran you are chartering has insurance. Also, carefully read and understand the catamaran charter agreement.
6. Equipment maintenance: Make sure that the equipment (sails, mast, mast bar, ropes, etc.) of the catamaran you will rent is regularly maintained. This is important to ensure your safety.
7. Number of crew: Determine how many crew members the catamaran you are chartering should use. This number may vary depending on the size of the catamaran, your level of experience and the route.
8. Water safety: Water safety is important when at sea with the catamaran. Always wear safety equipment and follow the rules when doing scuba diving, water skiing and other water sports.
