The Navigation Acts, in effect, gave a monopoly of colonial commerce to British ships.

实际上，《航海法》赋予了英国船只垄断殖民地商业的权利。

Thus the colonists in the end profited from the restrictive policy written into the Navigation Acts.

因此，殖民者最终受益于写入航海法的限制性政策。

The Navigation Acts, for example, redounded to the advantage of American shipbuilders and the producers of hemp, tar, lumber, and ship stores in general.

例如，《航海法》为美国造船商和大麻、焦油、木材和一般船舶用品的生产商带来了好处。

To the South the proposal was menacing because tariffs might interfere with the free exchange of the produce of plantations in European markets, and navigation acts might confine the carrying trade to American, that is Northern, ships.

对南方而言，该提议具有威胁性，因为关税可能会干扰欧洲市场上种植园产品的自由交易，而航海法可能会将运载贸易限制在美国（即北方）船只。
