About Johnstone Strait: Johnstone Strait is one of the main marine transit waterways for British Columbia, and a key part of the Inside Passage through southern British Columbia. But don’t let that fool you – there are alternatives for transiting the area, and so not surprisingly a great many recreational boaters instead transit this region by the backwater channels – Cordero Channel, Wellbore Channel and Chancellor Channel – as one set of options. This helps avoid both the traffic and the strong diurnal winds to which Johnstone Strait is prone. The trade-off, though, is rapids, and a series lie along the inner route that require careful consideration.
About this mapsheet: The Inside Passage Chart Assistant series is composed of 11 mapsheets designed to enable transit of the British Columbia coast from Washington State to Smith Inlet by using a uniformly scaled and continuous set of mapsheets. Since most mariners use electronic navigation, these mapsheets can be used for logistics and planning where a broad visual overview is necessary. You can read more about the Inside Passage series here. All Chart Assistants are printed on heavy synthetic paper to withstand the toughest conditions. All 11 are available as a package; three of the 300-series mapsheets are being sold individually. They include:
#304 Texada Island.
#305 Jervis Inlet.
#308 Johnstone Strait.
Combining with Deck Toppers: These mapsheets can be used in combination with the Deck Topper series to fill in the vast majority of the southern British Columbia coast. The above three mapsheets use a scale better suited to these locations than can be provided by the Deck Topper series. Use #308 Johnstone Strait to cover the area between #235 Discovery Islands North and #238 Broughton-Johnstone.
