Boats, yachts and daily tours can damage marine habitat with their hulls and anchors. In last decades,
research on the environmental effect of boats and yachts marine engine has tended to concentrate on
potential effects of oil spill, sewage, turbidity, noisy, antifouling paints and disturbance to wildlife.
In Turkey, Beydağları Coastal National Park that is one of the rare protected areas, hosting both marine
and terrestrial ecosystems, having unique natural and cultural resources and values and allowing a wide
variety of recreational activities. This paper presents assessment the effect boat and yacht activities on
marine flora and marine ecological quality of touristic tour destination in Phaselis bay. The study
compared the changes in water quality and vegetation between 2008 and 2015. Compared to the past, it
was determined that in sediment more damage occurred due to the anchoring of dense yachts and daily
tours. Anchor movements caused the loss of sea grass and traces left around it and an unhealthy
appearance of the seabed. Cover value decreased to 1% in seaweed. After the increase in the number of
visitors in the seven-year period, a 9-16-fold increase in nutrient elements and oil-gress concentrations
detected. The ecological quality status is in good quality in regions where visitors and yachts have low
impact. In areas with high yacht and visitor pressures, the ecological status is bad.
