Saltwater eats metal. You know that. The hull, the prop, the engine fittings — all of it taking a slow hit every time you put the boat in the water. R55 lanolin builds a waterproof barrier on those metal parts so the rust doesn't get a foothold. It's natural lanolin, not a synthetic that'll crack and peel by summer. Reduces friction on moving parts, conditions leather upholstery and marine textiles, and it's safe on rubber, plastic, and wood. Biodegradable, so you're not dumping harsh chemistry into the bay. 300g is the right size for a quarterly maintenance run or keeping in the boat's tool locker
