This all-new drive-on docking system from SportPort provides extra flexibility to meet your docking needs. The modular 500 Series uses foam-core technology so it's unsinkable. The large panels provide excellent stability under foot. All components are made of 100% noncorrosive materials for long life. The SportPort 512 Dock is designed for the new, bigger personal watercraft (4-stroke PWCs), kayaks, and inflatables. This 5' X 12' dock section can be interlocked with other SportPort Docks or Decks to customize your docking. Additional shipping charges due when ordered. Shipped ground only.
