About Seaport Inlet Marina
Seaport Inlet Marina is a 200 slip, full service, dry and wet storage marine facility located in Belmar, NJ, with an onsite marine retail store complete with any and all of your boating needs. We are NJ’s exclusive NorthCoast, Cape Horn & Jones Brothers Dealer and your local Yamaha and Suzuki Repair and Repower Center! Seaport Inlet Marina is Shark River’s closest marina to the ocean. We are east of the Route 71 Bridge, so there is no waiting for bridges, the tide, trains or traffic. You’ll be only five minutes to the ocean and some of the best fishing on the Jersey Shore!
