Although Nettle Net® BOAT POOLS® are manufactured from the most expensive, toughest and lightest hi-tech composite fabrics available, tears or punctures may occasionally occur - almost always from overlooked sharp objects such as barnacles, oyster shells, or exposed bolts. For simple net repairs, carry a needle and thread (preferably nylon or polyester) on your boat and simply stitch a torn net together. If you are not comfortable with tackling the job, give us a call. We can advise you or you could send the pool to us to do the job for a reasonable fee.
