SealLine map case perfect for navigation charts

SealLine waterproof map case

I just saw the holiday sale prices on watertight SealLine map cases through our affiliate Moosejaw and it reminded me that I had a hard time finding a high quality flexible chart and map case for use aboard our boat–but eventually found SealLine.  Perusing my favorite local outdoorsy shops I just wasn’t finding a high quality map case and ended up ordering online.  We’ve now had our SealLine map case for almost 3 years and we use it with chart books, charts, atlases, and cruising guildes where ever we sail. Sunshine, rain or drizzle, it’s pretty typical that we have the SealLine map case with a chart in it is sitting somewhere handy in the cockpit. Like the shot below from the GoPro mounted on the boom gallows. I am backing down the boat as David, on the foredeck, lets out the anchor chain and the chart is just to the right of the companionway door.

One of the more important asepcts of a watertight chart case for us is that the plastic is thick enough that the ship’s cat, Beryl, cannot easily carve holes into it with her claws.  Since she spends a good deal of time sitting on top of the charts and when she’s happy she kneads her claws in-and-out or when scared does a wild scramble with claws everywhere, this “Beryl resistent” feature is just as important as the watertight features like the RF-welded seams and zip type closure.  The thicker plastic is also important to resisting punctures from chartbook spines.

Taking advantage of the nice D-rings on the corners of the case, we’ve tied in the case when using it in the cockpit in high wind.  I also covered a couple diving weights with fleece so we could simply weight it down and let it sit on the bridge deck in similar conditions and with hopes of no Captain Ron moments for us.

SealLine says “You can depend on SealLine portable bags, packs, cases and accessories to keep your gear protected anywhere—from the urban jungle to farthest reaches of the globe. SealLine products are made of the highest-quality waterproof fabrics, and our proprietary RF-welding skills are unmatched in the industry. The result is unquestionable gear protection to help you survive the world’s most challenging environments.”  That sums it up pretty nicely.

We got the largest of the three available map cases–that one is 16″ x 22″ and works well to hold a folded chart or many of the chart books. With this large size, I found it convenient to place an open guidebook on one side and the applicable chart on the back side so I could flip the clear chart case over giving me access to both documents.  Though we do have a chart plotter in the boat that we can see through the compaionway door in a pinch, both David and I enjoy using paper charts as we travel.

Below, you can see the large size of the SealLine map case we have. It is always in use–in the picture below, it carries a chart atlas while crew-mates David and Beryl wait out a rainy day.
