Marina guide
Korth's Pirate's Lair Marina
Isleton, Sacramento County, CA
Overview
Korth's Pirate's Lair Marina is a full-service Delta marina at 169 West Brannan Island Road, near Isleton in Sacramento County. The state boating facilities directory places it on the San Joaquin River side of the Sacramento-San Joaquin Delta, a short drive past Brannan Island State Recreation Area.
Layout and capacity
The directory lists 212 slips and tie-ups, dry storage for 200 boats, one boarding float and 40 car-and-trailer parking spaces. That mix makes it a base both for owners who keep a boat in the water and for trailer and dry-stack boaters who want to be close to the main river.
What's on site
Korth's is one of the Delta's more self-contained stops. It sells fuel, runs a sewage and bilge pump-out, and has a convenience store, ice, a fish cleaning station, restrooms and showers. A restaurant and lodging are on site, and transient tie-ups are available, so boaters cruising the Delta can tie up for a meal or a night.
Boating here
The surrounding water is fresh, tidal and busy in summer with ski boats, cruisers and anglers. Golden mussel was confirmed in the Delta in October 2024, so clean, drain and dry your boat every time it comes out, and check with the next waterbody you visit before you trailer there.

Common boat service needs here
Hull cleaning in warm fresh water
Boats kept in Delta slips through the summer pick up slime and growth quickly in warm fresh water. With golden mussel now in the Delta, regular diver hull and running-gear checks matter more than ever.
Find Bottom Cleaning, Hull Cleaning & Dive Services providers →Engine and outdrive service
Long runs on the rivers, shallow sloughs and debris after storms are hard on props, outdrives and cooling systems. Seasonal engine service and impeller changes are common here.
Find Marine Mechanics & Engine Service providers →Washdown and detailing
Dry-stored and slipped boats both collect dust, bird droppings and Delta water spots. A regular wash and wax protects gelcoat between trips.
Find Boat Detailing & Washing providers →Canvas and covers
Hot, sunny Delta summers break down bimini tops, covers and vinyl. Owners often need canvas repair or replacement every few seasons.
