1·If you are looking for a large daysailer or a small cruising sailboat, you may be choosing between sailboats that have an inboard engine and those having an outboard motor.

当你在选择大型的日间帆船（不用于过夜航行的——译者注），或一艘小型的远航帆船时，你可能会面临在配置舷内发动机或舷外发动机的帆船之间做出选择。

2·It is MUCH quieter than my boat's inboard diesel engine, and more efficient than running the main engine just to top off the batteries.

它比我的船的船内的柴油发动机更安静，更比运行效率的主要引擎只是顶部关闭电池。
