31 May The Challenges of Navigating Fiji
Cruising through Fiji aboard Starr has been one of the most beautiful and challenging experiences of our journey so far. The islands are stunning, but navigating them safely requires a different level of attention and preparation.
One of the first pieces of advice we received from experienced local sailors was to only travel between 10:00 and 15:00. During those hours, the sun is high overhead, making it possible to see coral heads clearly through the water. Out here, your eyes are just as important as your electronics, sometimes even more so.
While Fiji is technically charted, much of the data used in modern navigation systems still traces back to Captain Cook’s original surveys from 1774. As a result, many of the charts are inaccurate, especially outside major ports and channels. Some areas are off by hundreds of feet or more, which makes careful route planning and real-time observation absolutely essential.
On board, we’ve adapted our navigation strategy accordingly. Normally, we rely solely on Coastal Explorer, but in Fiji, we’re using a three-chart system to cross-reference and verify our position:
Coastal Explorer with C-Map Charts — This is our usual setup, but here the charts are often inaccurate. It’s not uncommon to see ourselves placed on top of a reef when we’re actually in open water.

Coastal Explorer – Using the inaccurate C-MAP charts on the dim screen
Navionics on the iPad — Fairly user-friendly and often helpful, but still inconsistent in terms of positioning and accuracy.

Navionics – Semi Reliable and bright but on the small screen of the Ipad,
OpenCPN — Popular among sail-boaters
because it’s free and open-source. We’re using it primarily for satellite imagery overlays, which are incredibly valuable for spotting coral heads and shallow patches that don’t appear on standard charts. We load in imagery from multiple sources including Google Satellite, Bing Satellite, and NASA Satellite, and often switch between them. A cloud, shadow, or poor lighting in one image can easily obscure something critical, so being able to switch sources makes a big difference when navigating near reef edges.

Open CPN – Using the brighter screen to see the Satellite image better
No Foreign Land — A great program that is both a social media and navigation software for cruisers. It allows people to view the NASA Satellite
charts, post reviews about anchorages, beaches, even snorkeling!. In addition to all that, you can see other peoples boats, who is onboard, where they hail from ETC. In our short time here, it has become a lot of fun to check and an invaluable resource.

One of the unexpected challenges we’ve run into is screen visibility. The brightness of our current navigation monitors is limited to about 250 NITs, which might work fine in a dark pilothouse or at night. But in full daylight, especially under the intense Fijian sun, it becomes difficult to make out details on the screen. Even with shades and covers, reading charts or sonar data clearly during the day can be a real struggle.
We’ve been getting by using the iPad and other secondary displays, but it’s not ideal. When we reach New Zealand, one of our top priorities is to upgrade our monitors. We’re hoping to find either custom-built or prebuilt displays that can reach at least 1500 NITs. That level of brightness should improve visibility dramatically and reduce eye strain, especially when using satellite imagery as part of our daily navigation.
To add another layer of safety, we’ve also been relying heavily on our searchlight sonar. It gives us a real-time look at what’s beneath and ahead of the boat, which has proven extremely useful in tight passes and unfamiliar anchorages.
Between the tools, the local knowledge, and some traditional seamanship, we’ve been able to navigate confidently. Still, this region requires full attention. Every move is deliberate, every anchorage carefully considered, and each leg of the journey approached with caution.
Despite the extra work, cruising Fiji has been unforgettable. The remote islands, clear waters, and vibrant reefs make every bit of effort worthwhile.

Great to hear that you are enjoying the beautiful waters of the South Pacific. Fiji has always been a favourite place for New Zealanders to holiday. It’s not far to travel and there is such a variety of beautiful islands to visit.
Have you given any thought about wintering Starr in New Zealand? We would love to see you down here.
Fair winds
warmest regards

Who knew how complex navigating your vessel could be. I imagine that all your experience is invaluable for the many situations you encounter. My experience with boating is cruise ships. We didnt even think about what you encounter. We once had a rogue wave That was an experience I won’t forget.
You probably have an itinerary of your next adventure. Look forward to seeing what is next.
Live your exciting life on the water!
Thanks for the opportunity to see a different view of life!
Hugs

Posted at 06:45h, 31 MayI’ve also heard that sailing in Fiji is challenging, and that some charts in use today date back to Capt. Cook’s explorations., but your comments really bring the complexity home.
Really appreciate the detailed description of your navigation procedures.as well as the monitor issues.
Gretchen and I have just tied up dockside in Dublin after ten days of expeditions along the small islands of Wales and Scotland. No issues re navigating these waters.
Mahalo, and continue to enjoy our beloved Fiji, Bill & Gretchen

Posted at 23:34h, 31 MayWhat a wonderful tutorial on navigation and the charts and instruments all mariners rely on. Great to read about. How long will you stay in Fiji and are there other island groups nearby that are next on your agenda. Thank you so much for sharing this adventure.
