SRKW Interim Order and Sea Kayakers

Posted on June 22, 2019April 13, 2026 by Ruth Daber

Please note: This article was written in 2019 and the regulatory framework it describes has changed significantly. The Interim Sanctuary Zone no longer exists under that name, approach distances have been updated, and a shoreline corridor for human-powered vessels is now in place. For current information please read our updated guide: Kayaking near killer whales on Saturna Island: what paddlers need to know.

2019 article below.

From the perspective of a Saturna Island based Sea Kayaker and Paddle Canada certified Sea Kayaking Instructor.

Sea kayaking is a great way to explore Saturna Island and the Salish Sea. BC Marine Trails connect some of the Gulf Islands for kayakers, going around the east side of Saturna. The route connects Narvaez Bay and Cabbage Island campsites that have marine access. We wanted to know if the new Interim Zone to protect the Southern Resident killer whales (SRKW) would mean an end to circumnavigating Saturna Island by sea kayak.

SRKW Boiling Reef Interim Zone – shaded

The image that I drew over a nautical chart illustrates the Interim Zone (Saturna Island portion shown only, gray shade) which prohibits general vessel traffic including kayakers between June 1^st to October 31^st.

Here is a link to the Transport Canada issued Interim Order.

Sea kayakers travelling around Saturna Island must pass the east side of Saturna cautiously; keeping in mind currents, shipping channels and the United States border. A previous article took a look at currents around Boiling Reef. Avoiding the Interim Zone increases risks.

I compared two likely routes from the south east side of Narveaz Bay to Tumbo Island (both locations are en route when circumnavigating Saturna). The white line is the safer shore paddle route (about 2.6 nautical miles (NM)), the black line (about 3.5 NM) that avoids the Interim Zone is less safe.

While it potentially only takes 20 minutes longer to travel this way, it means that about 2 NM (40 minutes paddling for a good paddler and good conditions) would be in waters that are hazardous. Keeping track of the exact location of oneself and the Interim zone while travelling in a sea kayak and avoiding the shipping lane, requires good GPS technology or advanced navigation skills. There are no markers on the water. Sea kayakers most often travel along shores.

A safety-stop at Shell Beach helps a kayaker to assess current conditions for safe paddling (especially if travelling south). Whales do not usually come to Shell Beach, but technically speaking it is in the Zone. I had one close encounter with killer whales in a sea kayak. The whales were Transients and outside the Interim Zone, close to Fiddler’s Cove. The Interim Zone at large is mostly a place for transiting in a kayak due to the strong currents that often prevail… idling for long periods is rarely an option.

Saturna Islander, David Osborne phoned Transport Canada and received an official email response addressing some of his concerns.

Find the full email. Here is an extract:

“However, marine safety is priority. If it is unsafe to comply with the rules, vessel operators are exempted to avoid immediate or unforeseen danger. If this is the case, Kayakers must transit through the area (cannot idle) and stay a minimum 400 metres from whales when safe to do so. ”

So, if you see kayakers transiting the Interim Zone, they are likely doing so for marine safety reasons.

KayakingSkills.com promote best practices regarding wildlife, i.e. to not disturb the animal’s natural behaviour or put oneself at risk and to abide by advised distances when safe to do so.

To conclude, circumnavigation of Saturna Island is possible and if it is unsafe to comply with the Interim Zone, it is appropriate to transit through it.

Boating Hazards at Boiling Reef, East Point

Posted on May 11, 2019June 22, 2019 by Ruth Daber

Recent rescue scenarios at Boiling Reef prompted me to get this article out quickly. Just this past Easter Sunday two people using a small inflatable boat who had drifted beyond their control were rescued from the reef by Hovercraft thanks to the emergency call-out by some onlookers. A sailboat stranded on the reef and at several occasions over the past years, kayaks have capsized, and the paddlers were unable to re-enter without outside assistance, sometimes capsizing their peers that tried to help.

Visitors to Saturna Island are often unaware of the hazardous waters at Boiling Reef, East Point.

Look at the Nautical Chart and Current Atlas images to notice the hazards in the area. Both publications can be purchased at marine stores.

Boiling Reef, East Point Area

Unless you fully understand when to go kayaking (or boating in general), take a course first. These waters require the right boat, skills and conditions to safely navigate them. Shell Beach at East Point can occur deceivingly calm and sheltered. The current flowing between Saturna and Tumbo islands moves toward Boiling Reef at flood and ebb. A small vessel that is lightweight with a large surface area (i.e. inflatable kayak) quickly acts like a sail and becomes impossible to control in currents with enough wind added, even for an athletic person. Here strong currents, rips, eddies, waves and increase of wind effects are not obvious to the untrained eye and using a marine chart is crucial to help identify hazards.

Additional factors: Spring tides around full and new moons mean greater water fluctuation and faster currents, increasing the risk of capsize or being carried out and off to the United States. Capsize of any vessel can potentially lead to its passenger’s death by drowning or hypothermia after prolonged exposure to cold water.

When approaching a headland (i.e. Monarch Head, East Point), currents that funnel or form eddies can change significantly, also wind speed and direction, potentially resulting in a quite different sea state.

From East Point along Cliffside and all the way to Monarch Head there are potentially strong currents also, even at the occasion that Boiling Reef itself shows little indication. Our resources page has a link to current speed data for Boundary Pass near East Point.

Sea kayaks are designed with the ocean in mind but require training and practice for proper use. Some are intended to handle waves and dynamic conditions while others target forward speed on flat water and require more balancing skills. Recreational kayaks from large retail stores are typically made for flat, sheltered water and are unsuitable for venturing into areas like Boiling Reef, East Point. Some do not have enclosed buoyant compartments that displace water to prevent sinking if capsized.

Things you can do to paddle safely: take a course and learn about safe paddling conditions, gather local knowledge of areas you intend to explore, practice rescues, learn risk assessment and reading nautical charts, use the right boat and safety equipment, paddle with peers that also know how to rescue you, check weather, tides and currents, paddle in conditions that you are skilled to handle, and file a float plan with a reliable friend. Wear immersion gear and PFD, we are surrounded by cold water throughout the year. Avoid strong currents by choosing neap tides around first and third quarter moons.

Saturna’s Currents Decoded

Posted on September 29, 2018April 14, 2026 by Ruth Daber

Understanding sea kayaking currents around Saturna Island is essential for safe trip planning. If you haven’t already, our article Saturna’s Tides Decoded connects closely with this one.

The general direction of flood (feathered arrow) and ebb tidal streams around Saturna Island are shown in the image. Ebb and flood currents between Saturna and Pender Islands are generally less strong, and direction varies. For detailed information it is helpful to refer to the Current Atlas (Juan de Fuca Strait to Strait of Georgia) by the Canadian Hydrographic Service — a free PDF available from DFO. The publication has 93 scenarios of current direction and flow rate for our wider area. The corresponding Murray’s Table (free download, available through 2030, last checked April 2026) connects each hour with an applicable page. Note that currents at Boat Passage and similar narrow passages cannot be properly identified this way — the Current Atlas is better suited to reading the larger patterns of tidal stream movement across the region. Thick, fat arrows indicate strong currents of 2.5 knots and above. Be very cautious in the surrounding area.

For those who prefer a digital tool, the PNW Current Atlas app (iOS) combines the Current Atlas and lookup tables in one place. Bear in mind that like the printed atlas, it is best used for reading broader tidal stream patterns rather than precise timing at narrow passages like Boat Passage, which are not marked in the atlas. The app has a free trial after which you purchase it. I have found it most helpful to have accessible on my phone.

A newer alternative is the Salish Sea Tidal Current Atlas (SSTCA) by Dr. Richard Dewey of Victoria, BC. This free resource uses a higher resolution tidal model than the original DFO atlas and covers more of the Salish Sea. For our area around Saturna Island, download Volume 1E along with the SSTCA Volume 1 Calendar Lookup Tables for 2026. Note that the SSTCA shows a discrepancy in Tumbo Channel compared to the original DFO atlas. The DFO atlas shows the channel running in a back eddy around Tumbo Island, meaning that even when the flood direction everywhere else points northwest, the channel current runs southeast — something we have observed ourselves on the water. The SSTCA does not appear to recognise this back eddy. We recommend cross-referencing both resources and using your own observations when paddling this area.

Kayakers often travel close to shore and passing through back eddies that are circular currents running in reverse direction of the main current and are not necessarily indicated in the Current Atlas. I often look at bull kelp as I paddle to help me identify the direction of such currents.

Tumbo Channel currents always run toward East Point due to an eddie forming at Tumbo and Cabbage Islands. The only time the surface water does not move that way is when winds are stronger and force the surface water the other direction. Other than that, plan your sea kayaking trip taking advantage of the tidal stream whenever it is safe to do so (i.e. travel counter clockwise around Tumbo Island).

Boat Passage at Flood Current

Visit Boat Passage once a while from shore and view it at different flow rates. You may see a still pond and an hour later a raging river. With currents as strong as 6 knots, it can run twice as fast as the speed of an average skilled paddler. At high speeds expect turbulent water with whirlpools also. If not understood, Boat Passage can become a one-way trip ending in a rescue scenario or at best a very long wait for a turn of tidal stream flow. You can however cross many narrow passages by sea kayak during a predictable window of opportunity when tidal horizonal movement turns, called slack tide. To work out how much time you have to get through a passage, you need to know slack time as well as the maximum ebb or flood of the current before and after slack (typically around 3 hours before and after). I am going to pick an example here around a new moon when tidal ranges are great. Let’s say that you want to get through Boat Passage on Sunday June 28th, 2026, a few days after a new moon when tidal ranges are greatest, and wonder when it is safe to do so. There is no current station measuring speeds and times here; data is derived from surrounding current stations. We find the numbers close to what happens. Look up maximum ebb (into Winter Cove), slack time and maximum flood currents (toward Vancouver) and click through to currents at Boat Passage (and choose the date):

Max Ebb: 3.5 knots
Slack: 9:40am
Max Flood: 5 knots

Apply the Slack Water Rule:

Period of Slack Water (minutes) = 60/Speed of Max Current (knots)

Period of Slack Water = 60/3.5 = 17 minutes (before slack)
Period of Slack Water = 60/5 = 12 minutes (after slack)
Total Period of Slack Water = 17+12 = 29 minutes (starting 17 minutes before slack water at 9:40am, so at 9:23am)

This formula calculates how much time there is to safely get through a passage by sea kayak. Always arrive early, so that you can allow for variables and be flexible if conditions are beyond your skill level. If you are not sure it is safe, apply common sense and don’t cross till you have gained more skills as well as better judgement. Always be aware of your surroundings and other boats passing through, some of which are unable to move out of the way, if you move into theirs. Boat Passage is a very short passage and therefore travelling through it under the right conditions is fast. If you wanted to get through Active Pass, you want to be aware of the much longer distance and time needed to travel through it. If your paddling speed is 3 knots, just one knot of current against you, will slow you down to 2 knots. One nautical mile will take you 30 minutes instead of 20. While not the whole stretch of Active Pass encounters the strong currents, certain areas are extremely fast flowing with whirlpools and in addition ferry traffic and waves to look out for.

Great, now that you can figure out when to get through Boat Passage safely, think about the rest of your trip. Will you go to a destination beach and return in around six hours with the next slack time? Or will you carry on your journey to a different destination. If you are planning on going around Samuel Island, beware that the passage between Samuel and Mayne Island also has currents that can be significant for a paddler.
