The Nautilus VII live-aboard dive boat does multi-day trips ranging from two to seven days from February through early November. Trips run US$133 per person per day and include food and heavy gear (tanks, weights). The boat can pump high-pressure steel tanks and supply nitrox. Diving the northern end of Vancouver Island is not for novices, especially divers unfamiliar with currents and very cold water. In addition to the adrenaline-pumping Nakwakto run, the Nautilus also does more benign trips to calmer waters along Vancouver Island. Water clarity in the Canadian northwest is usually best during cold months when plankton dies off, but the weather is far more comfortable in summer; even in August, you can usually avoid the worst of the plankton blooms. Early fall and late spring can be pivotal times, with warm, clear weather and decent water visibility. For that reason, spring and fall are very popular dive seasons in the northwest.
