I'm Kirby, the designer of the Orange Screw
. I thought I might chime in and address a few comments. I've spent the last 25 years on the river in kayaks, canoes and rafts as both a guide and a private boater.
Our family uses the LARGE Orange Screws on rafting trips as another anchoring option for the river wing. The plastic stakes that come with most shade/river wings only work in a fairly narrow range of conditions- the Orange Screws widen that range significantly. I keep at least 4 large screws and a few metal nail-type stakes in our kit and this will allow bomber setup in most conditions.
The SMALL Orange Screws are great for the tent rainfly on river trips or any foul weather camping situation. A few will do the trick- I usually use them on the windward side of the tent so I don't have to scramble half-naked in the middle of the night to re-anchor my tent. The small screws are also great for the large family tents like an REI Kingdom 6 or 8.
I do not typically use the Orange Screws for anchoring boats overnight unless the riverbank is firm soil and the eddy is mellow. For most river trips, the large 2x2x24" sand stakes are still the go-to choice for holding boats with "sleep through the night" security.
Orange Screws are definitely a lightweight and useful tool on the river. You can keep 6 large ones in your drybox for under 1.5 lb and I guarantee you will use them. Its just another option to keep in your kit.
Orange Screws are made in the USA out of recycled materials.
We are on Kickstarter until Sept 14. The KS price is slightly less than retail. Let me know if you have any more questions. Thanks!
