Embark on adventures across Bristol Bay and beyond with charts tailored for the wild Alaskan waters. This collection spans from Sutwik Island along the Alaska Peninsula up to Kotzebue Sound, capturing key spots like Dillingham, Kvichak Bay, Port Moller, Chignik Bay, and Norton Sound. It even extends to the Aleutian Islands, including Unalaska Island to Unimak Island with Akutan and Unimak Pass. Whether you're chasing salmon runs in Bristol Bay or exploring remote inlets, these charts deliver the detail needed to handle shifting sands, strong currents, and hidden reefs that define this region.
For anglers and boaters familiar with Alaska's fishing grounds, the enhanced bottom structure mapping shines in areas like Kvichak Bay, where precise contours can mean the difference between a trophy catch and getting grounded. Integrated data from trusted sources ensures your plotter reflects the latest nautical intelligence, helping you focus on the thrill of the journey rather than second-guessing your path.
These charts go beyond basic lines on a screen, blending advanced visualization with smart routing to elevate your on-water experience.
Picture plotting a course through the maze of shoals in Norton Sound without the hassle. Auto Guidance factors in your boat's draft and overhead obstacles, generating a suggested route that's safe and efficient. It's especially handy in Alaska's variable tides, where manual plotting can eat up valuable fishing time. Just set your parameters, and let the tech handle the rest—always cross-check with your eyes and instruments for ultimate safety.
Traditional contours are great, but relief shading adds shadows and color gradients for a bathymetric view that's intuitive at a glance. In Bristol Bay's shallow bays, this reveals drop-offs and humps where fish school, making it a game-changer for bottom-fishing pros targeting halibut or king salmon.
Dive into FishEye view for an underwater lens on contours and structure, ideal for spotting wrecks or reefs below. Switch to MarinerEye for a cross-section above and below the surface, giving context in foggy Aleutians or cluttered anchorages. These aren't gimmicks—they're tools that build confidence in unfamiliar territory.
High-res imagery layers ports, bridges, and landmarks right over your charts. Entering Chignik Bay? See the layout before you arrive, reducing surprises and boosting efficiency during multi-day trips.
Alaska's weather shifts fast, and these charts pair perfectly with modern chartplotters. Load them onto your microSD or SD card for seamless integration. Pro tip: Pair with sonar for live bottom tracking—relief shading aligns beautifully with real-time fish arches. In remote areas like Kotzebue Sound, where cell service fades, this offline detail becomes your most reliable crew member. Always update via official channels to stay current with notices to mariners, and practice routes in simulator mode before heading out.
It covers Bristol Bay and the Alaska Peninsula from Sutwik Island to Kotzebue Sound, including Dillingham, Kvichak Bay, Port Moller, Chignik Bay, Norton Sound, and the Aleutian Islands from Unalaska to Unimak Island with Akutan and Unimak Pass.
Auto Guidance calculates routes based on your specified depth and clearance, providing a suggested path. It's a planning tool—always verify with visual navigation.
Relief shading uses color and shadows for a 3D-like seabed view, making structure like drop-offs easier to interpret quickly compared to lines alone.
Absolutely—1-foot contours and depth shading highlight prime fishing structures, ideal for salmon and halibut in bays like Kvichak.
They come on microSD/SD cards, compatible with most Garmin chartplotters for easy plug-and-play use.
Yes, FishEye offers underwater 3D contours, while MarinerEye shows above- and below-water perspectives for better orientation.
You set a custom depth threshold, and it shades shallows to avoid, crucial in tide-influenced Alaskan coasts.
