Loomis Marine Products knows fishing. Since 1980 we’ve delivered innovative fishing gear that is proven to save money and stand up to unprecidented wear and tear. Because we know it’s about more than catching fish.
Today’s fishing fleets must also manage marine resources, perform emergency medical care, maintain equipment, understand complex and ever-changing rules and regulations, and administer employees. Fishing is serious business. And while we can’t necessarily make your crew better fishermen, we can ensure that our quality products will give them more time to fish.

Purse Rings (Non-Metallic)
Loomis Marine Purse Rings improve maneuverability and extend the use-life of purse lines. Their self lubricating properties work like oil to help purse lines slide freely through the rings. Reduced abrasion means lines last longer. Molded with a patented thermal plastic polymer process, our purse rings are designed to withstand extreme stress loads. And because they are non-metallic, these purse rings won’t scratch hull paint or fall susceptible to the effects of electrolysis on aluminum decks.

Net Rings & Trawl Rings
Smart, simple design allows Loomis Marine Net and Trawl Rings to carry large loads while reducing line abrasion. The marine grade resins we use allow for stress loads up to 2,600 pounds and the self-lubricating properties of our unique polymers reduce friction and extend the life of your lines. They are perfect for brailer closings to cod ends on trawl nets, or even to purse the opening on crab pots.

Pot Saver
Loomis Marine Pot Savers help crabbers lessen the chance of losing pots when crab lines get crossed during haul-up. Working like a pulley, the pot saver allows wrapped lines to free-wheel their way topside. With self-lubricating properties, they also prevent lines from being chafed, which has proven to reduce the incidence of lost pots from severed lines saving hundreds of dollars. Marine grade plastic withstands high abrasion and extreme stress loads. Every pot should have one!
