Wakes generated by recreational boats have the potential to erode the shoreline, damage infrastructure, or disrupt aquatic ecosystems. Therefore, boat wakes are an increasingly important focus of coastal management, particularly along vulnerable shorelines. This short communication quantifies the relative importance of recreational boat wake energy along the shoreline of an inland cottage lake in Northern Ontario, Canada. Measurements of recreational boat wakes at the end of one of the longest fetches for locally generated wind waves on the lake account for >61% of total wave energy. Based on this result, recreational wake energy likely is the primary source of wave activity along sections of the lake adjacent to the primary sailing lines but not aligned to the primary directions of wind wave energy. Recreational boat wakes may be a significant source of wave energy on other inland lakes.

休闲船只产生的尾流有可能侵蚀海岸线、破坏基础设施或破坏水生生态系统。因此，船尾是海岸管理越来越重要的焦点，特别是在脆弱的海岸线上。这个简短的交流量化了加拿大安大略省北部一个内陆小屋湖海岸线的休闲船尾流能量的相对重要性。在湖上本地产生的风浪的最长提取之一结束时对休闲船尾流的测量占总波浪能的 61% 以上。基于这一结果，休闲尾流能量可能是沿与主要航行线相邻的湖泊部分波浪活动的主要来源，但与风波能量的主要方向不对齐。
