Long-term changes in recreational craft utilisation on Loch Lomond, Scotland

We present data from censuses of recreational boating activity on Loch Lomo nd, Scotland from 1989 to 1999 that demonstrate increases in craft numbers, as well as changes in the type of recreational boating pursuits conducted over this period. Using these data in a simple regression model that assume s a continuation in the current rate of growth of boating activity, we pred ict that craft activity will double in approximately eleven to thirteen yea rs. We also show changing patterns of the type of recreational boating acti vities being conducted on Loch Lomond, with the general trend being a switc h from slow moving powered craft towards higher speed craft with more power ful engines. Speed restriction bylaws introduced in February 1996 have had no depressing effect on overall craft use but appear to have resulted in so me change in craft activity within the loch and thus they may be a signific ant tool in recreational craft management.
