Thirty years of use and experience in the bays, rivers, and estuaries along the Atlantic Coast and thousands of satisfied customers attest to the effectivness of the Nettle Net Boat Pool in waters populated by the common, mildly stinging jellyfish of these regions. The pools have proven through years of experience to effectively create a jellyfish free swimming area. The pools have worked successfully in areas populated by Sea Nettles (Chysaora Quinquecirrha), the most common stinging jellyfish of Chesapeake Bay and along the Atlantic Coast, and the Lions Mane and Moon Jellyfish in these regions. The degree of pain from a sting varies from person to person and with the severity of the encounter with the stinging tentacles.
The mesh netting on the pools is by neccessity porous so that water can flow through the pools and allow the pools to function as swim areas. Since the mesh netting is not an impermeable barrier, it is theoretically possible that some stingers could be felt through direct contact with a jellyfish through the netting. There is no guarantee that a user cannot be stung through the pool netting. Due to the slight chance that someone could possibly be stung through the netting we do not recommend the pools be used by any person who, for physical or emotional reasons, cannot tolerate the risk of a jellyfish sting.
We do not recommend that the pools be used as protection against certain types of jellyfish. These include, among others, the Portugese Man O'War (which is not technically a jellyfish), and certain highly toxic jellyfish, many of which are often found in tropical waters, such as Box jellyfish and Irukandji jellyfish. On the Atlantic Coast, Portuguese Man'O War tentacles can grow up to 20 or 30 feet long. At that length, they could wrap around a pool. In addition, there is documentary evidence that Man'O War stingers can penetrate through latex gloves, which are impermeable barriers, and of a greater thickness than the netting of the pools.
We do not recommend the pools as a defense against Sea Lice, like the type found periodically in South Florida and along the coast of Mexico. These pin-head sized creatures are small enough to float into the netting.
We do not recommend using the pools for protection from highly toxic jellyfish. Swimmers should avoid waters inhabited by these creatures.
We do not recommend use of the pools by people who could have potentially severe allergic reactions to jellyfish stings.
