Marine Navigation Disclaimer

Last Updated: July 12, 2026. Please read this disclaimer carefully before conducting any voyage planning.
Not a Substitute for Official Charts
All maps, anchorage ratings, route guides, and conditions data on PWSGUIDE.com are provided for general planning reference only. They are not a substitute for current official NOAA nautical charts, official tide and current predictions, or official marine weather forecasts. Always cross-check with official sources before and during any voyage.
Live Data Limitations
Conditions, tide, weather, and tunnel schedule data displayed on this Site are pulled from third-party public sources and may be delayed, cached, incomplete, or temporarily unavailable. PWSGUIDE does not guarantee the real-time accuracy of any displayed data. Before departure, verify conditions directly with the original source (e.g., NOAA, the Whittier tunnel authority at 1-877-611-2586, or VHF Channel 16).
Anchorage and Route Ratings Are Subjective
Protection ratings, exposure classifications, and difficulty labels (e.g., "Protected," "Exposed," "Advanced") reflect general characteristics and editorial judgment, not a guarantee of safety under any specific conditions. Conditions at any anchorage or route can change rapidly and may differ materially from the description shown.
No Emergency Monitoring
PWSGUIDE does not monitor vessels, routes, float plans, or user activity in real time, and cannot detect or respond to an emergency. In an emergency, contact the U.S. Coast Guard on VHF Channel 16, or call 911 if in range. Do not rely on this Site for emergency response of any kind.
Cold Water and Remote Rescue Risk
Prince William Sound waters are cold year-round, and rescue response times may be significantly delayed due to remoteness. Statistics referenced on this Site regarding survival time or rescue windows are general estimates, not guarantees, and actual conditions may be worse. Always carry appropriate immersion/survival gear and communication equipment independent of this Site.
Wildlife Viewing
Any wildlife sighting information on this Site is for general awareness only. Users must independently comply with all applicable federal marine mammal viewing distance regulations. PWSGUIDE does not endorse close approach to marine mammals or wildlife.
No Liability for Navigation Decisions
THE AUTHORS, OWNERS, AND OPERATORS OF PWSGUIDE ASSUME NO LIABILITY FOR ANY NAVIGATION, ANCHORING, OR ROUTE DECISION MADE USING THIS SITE, OR FOR ANY RESULTING INJURY, DEATH, VESSEL DAMAGE, OR PROPERTY LOSS.
