Lashing is through the welded webbing anchors along the centreline using releasable hardware only. Because a zippered case is not sealed with retained air, Kayak Canoe Waterproof Rifle Case does not float, and paddling programmes on deep or moving water should be quoted the roll-top range instead. Rolled length can be shortened for cockpit and tank-well stowage against a reference craft.
Stowage height is 8 cm against 25 cm for the roll-top tube, which places the load lower in the hull. Capacity is approximately 25–30 L against approximately 60 L, and the tube retains air and floats where this case does not. Water type therefore decides which of the two is specified.
Flat welded body suited to hull-floor stowage
| Factor | SL-E603 flat 8 cm | SL-E302 tube 25 cm |
| Height above the hull floor | 8 cm | 25 cm |
| Effect on centre of gravity | Low | Higher |
| Fits under a kayak deck or thwart | Yes | Often not |
| Sits in a shallow canoe bilge | Lies flat in the curve | Rolls against the curve |
| Under-gunwale locker | Suits the shape | Too deep for most |
| Capacity | 25–30 L | approx. 60 L |
| Floats if released in a capsize | No | Yes, sealed with retained air |
On a craft where a few centimetres of load height changes how the boat behaves, the flat profile is a genuine handling advantage. It comes with a limitation that outweighs it in some conditions.
| This case does not float.Buoyancy on our roll-top range comes from air deliberately retained before rolling, and a zippered case is not sealed that way. If a paddler capsizes and the case comes free in deep or moving water, it will sink. Anyone paddling water where that is a realistic outcome should be sold the roll-top tube, which gives up the flat profile to gain buoyancy. |
What the Kayak Canoe Waterproof Rifle Case does provide in a capsize is a firearm that stays dry inside it, rated to immersion at one metre for thirty minutes. That is worth something if the case is recovered — and nothing if it is not.
| Paddling Situation | Recommended | Reason |
| Sheltered water, case lashed | SL-E603 flat | Low stowage; recovery risk minimal |
| Shallow marsh and backwater | SL-E603 flat | Case can be recovered from the bottom |
| Deep lakes | SL-E302 roll-top | A sunk case is unrecoverable |
| Moving rivers and whitewater | SL-E302 roll-top | Current carries a case away; it must float |
| Portage-heavy routes | Either | Flat carries better; tube floats better |
| Sit-on-top with open deck | SL-E302 roll-top | Exposed carry; overboard risk is real |
A case that slides changes trim mid-stroke, and one that cannot be released is a hazard in a capsize.
1. Lash through the welded webbing anchors, never through the strap loops alone
2. Run the lash along the centreline so the case cannot slide side to side
3. Use a releasable knot or quick-release hardware — never a fixed tie
4. Keep the release reachable from the paddling position and practise it before it matters
5. Lash before getting in and release before stepping out
Because this case will not float free and wait, the lash is doing more work here than on a buoyant case. A released tube can be recovered at the surface; a released flat case cannot.
Canoe routes alternate paddling and walking. The flat profile carries against the back better than a tube, which rolls and sits away from the body, and the removable strap means the case stows without hardware catching on other gear during a portage.
For routes with many portages and sheltered water between them, the flat case is often the better overall choice. For routes with long open crossings, buoyancy outweighs carrying comfort.

The capsize result is published as it stands. The case sinks and the firearm inside stays dry, which is exactly what a non-buoyant waterproof case does, and paddlers should choose knowing it.
Sheltered water paddling with the case lashed; marsh, backwater, and shallow access where a sunk case can be recovered; portage-heavy routes between sheltered stretches; canoe hunting on calm water; kayak fishing and hunting where deck or locker depth rules out a tube; and any paddling programme where stowage height matters more than buoyancy.
Routes were portage-heavy across sheltered lakes, so carrying comfort and low stowage mattered more than buoyancy on their water. We supplied the flat case with quick-release lash hardware and a high-visibility colour split for shallow recovery, and quoted the roll-top for their one open-crossing route. 300 pcs, 43 days.
Sit-in kayak tank wells were too shallow for a tube. The 8 cm profile fitted, and we shortened the body for cockpit stowage against a supplied reference kayak. Their open-water customers were directed to the roll-top. 400 pcs, 44 days.
We recommended against this case for their use. Moving water meant a released case would be carried away and sunk, so buoyancy was not optional, and we quoted the roll-top instead. They ordered the flat case only for their lake-based camps. 150 pcs flat, 350 pcs roll-top, 45 days.
“You told us not to buy this one for the river. That is the reason we bought the other one from you as well.”
— Owner, Guided River Operation
“The tank well is shallow. Nothing waterproof fitted until this, and the rating is the same as the tube.”
— Product Lead, Kayak Fishing Brand
“Portages every hour and calm lakes between. Flat carries better and we accepted it does not float.”
— Head Guide, Canoe Outfitter
No. Buoyancy on our roll-top range comes from air deliberately retained before rolling, and a zippered case is not sealed that way. Released in deep water it will sink.
Stowage height. At 8 cm it lies against the hull floor where a 25 cm tube sits proud, keeping the load low on a craft where centre of gravity decides stability. It also fits shallow tank wells and under-gunwale lockers a tube cannot enter.
Deep lakes, moving rivers, whitewater, and exposed open-deck carry — anywhere a released case would be unrecoverable. Those customers should be sold the roll-top tube.
The case sinks and the firearm inside stays dry, rated to immersion at one metre for thirty minutes. That is worth something if the case is recovered and nothing if it is not, which is why water type decides the choice.
Through the welded webbing anchors rather than the strap loops, along the centreline so it cannot slide, using a releasable knot or quick-release hardware. Never fix it permanently — in a capsize, gear that cannot be freed is a hazard.
Yes. A released tube can be recovered at the surface; a released flat case cannot. The lash is doing more work here, and the release should be practised before it is needed.
Often, where a tube will not. Send the well dimension or the kayak itself and we will fit a sample at sampling, and shorter bodies can be tooled for cockpit stowage.
It carries against the back better, because a tube rolls and sits away from the body, and the removable strap means nothing catches during a carry. On routes with long open crossings, buoyancy outweighs that.
The welded shell and hardware are unaffected. Rinse the zipper track with fresh water and run the slider through, since silt and salt between the sealing faces are what degrade the closure.
Yes, and several paddling customers do — the flat case for sheltered and portage routes, the roll-top for open water, with counter guidance on which to recommend.
A high-visibility colour split aids locating a case at the surface or in shallow water. Khaki, black, and army green are available in any two-tone combination.
MOQ 300 pcs, samples in 7–10 days, production in 30–45 days, quoted EXW, FOB, or CIF, with development covering lash anchors, body length and thickness, colour split, hardware, and packaging.
