This invention relates to a multi-purpose, eco-safe bag for your gear which can be used interchangeably as a sand anchor to keep your stand up paddle board, kayak, or raft anchored in position while you are snorkeling, fishing, doing yoga, or just relaxing and hanging out in the water. Fill The SUPSAC with beach sand and attach to a leash or any length of rope to secure. The SUPSAC may also be used to secure beach umbrellas or canopies. This product is easily transportable at approximately 14 inches by 11 inches, light weight and multi-purpose. This product has no sharp blade type pieces which could harm the ocean environment, sea life, or another person. This product will not get hooked onto seagrass, corals or stuck on rocks as a claw type anchor would therefore making it an eco-safe product. When finished, simply empty the sand back into the water, returning it to its natural environment, re-pack your gear inside the canvas bag and continue on your paddle adventures.

A deep-sea anchoring device for gravity and anchor composite with a decelerating wing includes an anchoring base, a decelerating wing and an anchor body. The anchoring base provides an anchoring force by its own gravity, heavy pressure and friction with a sea floor. The decelerating wing includes a main decelerating wing, and a secondary decelerating wing that increases the cross-sectional area for diversion, so that a resistance is produced by water flowing through the main and secondary decelerating wings to reduce the falling speed of the anchoring base to a safe range, and prevent the anchoring base from being damaged by its collision with the sea floor. The anchor body is pivoted to the bottom of the anchoring base and anchored by being shoveled into a sea floor mainly consisting of gravels or deposited soil or abutted against rough rocks of a sea floor mainly consisting of rocks.

A sea anchor includes a textile tube and a resiliently flexible support. The textile tube may include a first end and a second end. The first end may have a rim defining a mouth and the second end may be closed. In various embodiments, the resiliently flexible support is coupled to the first end of the textile tube. The resiliently flexible support, in response to the sea anchor being deployed, may be configured to expand the mouth and retain the mouth open. In various embodiments, the textile tube has a conical shape, with the mouth of the first end being a base of the conical shape and the second end being a point of the conical shape. The resiliently flexible support is a ring coupled to the rim of the first end of the textile tube, according to various embodiments.
