Warnings and Cautions

Nettle Net BOAT POOLS have been used successfully for 30 years for jellyfish protection by thousands of customers in the Chesapeake Bay region and along the Atlantic Coast to create jellyfish free swim areas from their boats and docks.

However, as with any water-based product, there are inherent risks associated with using the pool and there are several unique precautions that should be followed at all times while using a Nettle Net.

The following are some of the risks and precautions associated with using a Nettle Net BOAT POOL: 

  • NEVER DIVE OR JUMP INTO THE POOL.  This Nettle Net, as with any swimming pool, can be used dangerously and injury or loss of life could occur if due precaution is not taken. The Vessel Captain or dock Property Owner must warn crew and guests, including children, that under no circumstances should they dive or jump into a Nettle Net Particularly, always use a ladder, never jump from the boat into the Nettle Net as one can easily slip on a wet deck or rail, hit another person or tear the netting from the ring. Also, warn your crew that under no circumstances should anyone dive into the pool. Nettle Nets are not safe for diving and the water bottom is too variable in depth. Serious injury can result from diving or jumping into the Nettle Net.
  • NEVER ENGAGE A BOAT'S PROPELLER.  Under no circumstances should the boat's propeller be engaged while a Nettle Net is in the water. The Nettle Net could be wrapped around the propeller destroying it and causing serious injury or death to swimmers.
  • THIS PRODUCT IS NOT A PERSONAL FLOTATION DEVICE.  People who need to wear a Personal Flotation Device (PFD) to swim should wear a Personal Floatation Device (PFD) in a Nettle Net BOAT POOL
  • POOLS ARE ONLY TO BE USED IN THE WATERS OF NORTH AMERICA. DO NOT USE THE POOL AS PROTECTION AGAINST HIGHLY TOXIC JELLYFISH.  Swimmers should avoid waters inhabited by these creatures.  Thirty years of use and experience in the bays, rivers, and estuaries along the Atlantic Coast of the U.S. and thousands of satisfied customers attest to the effectiveness 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 (Chrysaora Quinquecirrha), the most common stinging jellyfish of Chesapeake Bay and along the Atlantic Coast, and the Lions Mane jellyfish and the Moon jellyfish of these regions. These types of jellyfish all have relatively mild but annoying stings. 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 necessity 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 the netting if there is direct contact with a jellyfish or its stinging tentacles. 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 that 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 Portuguese 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 to lengths of more than 20 feet. 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 much greater thickness than the netting of the pools.

  • NOT RECOMMENDED FOR PROTECTION AGAINST SEA LICE.  We do not recommend the pools for protection from Sea Lice, like the type found periodically in South Florida and along the coast of Mexico. These pinhead-sized creatures are small enough to float through the netting.
  • ONLY USE THE SUPPLIED FOOT PUMP TO INFLATE THE POOL.  Only use the supplied foot pump to inflate a Nettle Net.  The pools only need 3 – 4 psi to fully inflate. Electric or compressor pumps can easily exceed that pressure and can blow a seam on the pool, ruining the pool. The included foot pumps work very well and the pools cannot be over inflated with them. Using an electric or compressor driven pump will void the pool warranty.
