General information

This Drifter CS 1300 OK is very luxuriously equipped. While you sit in the cockpit, you feel a great connection with the water and surroundings. In addition, the design allows you to reach unheard-of areas for a boat with an aft cabin.

The low clearance height of just 2.60 m also allows for sailing on secondary waterways with low-fixed bridges. With two sleeping cabins, this exclusive motor yacht is ideal for four people. On this boat, there are virtually no differences in level and, therefore, no stairs or walkways. It is easier to get on and off the ship with an open cabin boat. The sense of space is also enhanced, as you can fully open the cockpit doors.

Ultrasonic III also features an electric anchor, a combination oven and a washing machine.

Insurance and deposit

All our ships are all-risk insured. For this, you pay a security deposit of 750 euro. If there is damage, please fill in the damage form on board. On your return, give this to the harbour master. She will retain the deposit and handle the settlement with the insurance company.

Have you caused damage to another vessel? Always take photos and write down all details clearly. This way, we can contact the relevant party. Would you like the option of cancelling your boating holiday? You need to arrange cancellation insurance yourself. The HISWA conditions also contain information on this.
