DENDEN Maritime

About Us

Founded in 2005 by Tamer KÖSEOĞLU, DenDen Marine has been increasing its fleet in the motor yacht class and continues to serve as a leading corporate yacht charter and event organization company in the Istanbul Strait, with professional service quality.


Since its establishment, our company continues to provide VIP service with the comfort of a hotel through its fleet of 8 VIP motor yachts to Istanbul's most distinguished hotels, leading agencies, and event companies; foreign guests visiting our country, politicians, actors, artists, athletes, and sports clubs; and also to state institutions and organizations such as the Presidency, the Prime Ministry, and the Istanbul Governorship.


To offer our services in the best way possible and to provide an unparalleled sailing pleasure, Tamer KÖSEOĞLU's latest project, our DenDen Istanbul yacht, was completed after long efforts on April 29, 2023, and has been offered to our guests' appreciation in the Istanbul Strait. With the start of the summer season, DenDen Istanbul has accompanied and hosted those who wish to meet the beauties of Bodrum with the pleasure of yachting.


Furthermore, outside of tourism purposes, our ambulance boats named Denden 10 and Denden 11, manufactured by our company in 2017, have been added to our fleet; they are operated under the Ministry of Health and continue to serve at full speed in solving the sea transportation problem of the Islands.


Our company vision is to renew our fleet every year without compromising quality and to add new VIP boats to our fleet, which is our most important feature.


In this context, offering the best service quality in the industry in light of innovative thoughts with changing expectations, achieving all requests from our valued guests to the highest level within the scope of feasibility, has been an indicator of our company's successes and being the preferred company.


Just as Istanbul always brings the Istanbul Strait to mind, we are committed to our efforts to ensure that when the strait is mentioned, DenDen Marine is always thought of, and we continue to maintain our position at the top of the industry.
