The launching of craft from designated access points is likely to have minimal impact on marine features except where it involves trampling and scouring of the feature.

The launching of craft from informal access points, which is relatively common for small dinghies and windsurfers, may result in compaction and erosion of feature and damage to vegetation.

Although most litter in the marine environment is from sources other than water-based recreation, irresponsible behaviour from some boat users may contribute to the problem.

Disturbance can be caused to wildlife by the presence of dinghies and windsurfers in areas inaccessible to larger craft, including nesting sites. The impact will vary depending upon the type of activity, the time it takes place and the vulnerability of the wildlife.

Disturbance is observable at feeding, mating and roosting times but the impact is extremely difficult to quantify and should be examined on a case by case basis.

Dinghy sailing and windsurfing is more widespread than other water-based recreational activities and tends to take place throughout the year, sometimes coinciding with vulnerable periods for wildlife.
