The best sandbars in Ocean City, MD for pontoon boats are along the bay-side of Assateague Island, in Sinepuxent Bay south of the Verrazano Bridge, and around the flats in northern Isle of Wight Bay. Sandbars are the centerpiece of a great pontoon day in OC: anchor up, hop off into knee-deep water, run the cooler down the swim ladder, and let the kids and dogs roam. This is the closest thing to a private beach without paying for one.

Sandbars in OC are constantly shifting because the bay is shallow and the storm season redraws the bottom every winter. The general zones below are reliable year to year. The exact contours within them change. The good news: a pontoon only drafts about 12-15 inches, so you can poke around and find the right spot in real time.

Where the Sandbars Are

OCA Watersports pontoons launch from 12817 Harbor Rd, Ocean City, MD 21842. From the dock you have full freedom of the bay. North to the Rt 90 bridge, south past the Rt 50 bridge into the Sinepuxent and along Assateague. That is the largest boating area in all of Ocean City and it covers every sandbar zone listed below.

Assateague Island Bay-Side

The west side of Assateague Island, from the Verrazano Bridge south, is sandbar central. Look for tan-colored shallow zones a few hundred yards off the island shoreline. The water is typically 1-3 feet at low tide and 4-6 feet at high tide. Pull up parallel to the bar, drop the bow anchor in the sand, and you are set.

Bonus: this is also wild horse country. If a band wanders down to the bay shore, you have a front-row seat from your boat. We covered that in detail in How to See Wild Horses on Assateague Island from the Water.

Sinepuxent Bay

South of the Verrazano Bridge, Sinepuxent Bay opens up wide and shallow. There are several bars in the middle of the bay that are completely surrounded by water (the classic, true sandbar). At low tide you can stand a hundred yards from the nearest land in shin-deep water. Less boat traffic than the inlet zone, so it is the quieter sandbar option.

Isle of Wight Bay (North)

North of the Rt 50 drawbridge, the Isle of Wight Bay has a few notable bars along the west side near Bishopville Prong and across from the Ocean Pines marina. These bars are closer to the OCA dock and great if your group only wants a quick sandbar stop rather than a long southern run.

Tides Make or Break the Day

The single most important variable for a sandbar day is the tide. A sandbar that is perfect at noon can be an island at 4 PM or fully submerged at 6 PM.

The sweet spot: arrive at the bar about an hour before low tide. The bar will continue to expose as you sit there, you can wade further out as the water drops, and you still have time to leave comfortably before the incoming tide rebuilds. The first two hours of incoming tide are also great because the new water rolling in is cleaner and cooler.

Avoid arriving on a hard falling tide late in the day. If you anchor in 2 feet of water and the tide drops another 2 feet, you will be sitting on the bottom for hours waiting for it to come back. Pontoons handle this without damage, but it ends the day early.

OCA staff will give you a tide briefing at the dock before every pontoon rental. If you do not boat often, just ask, "Where should I be at what time today?" We will mark the chart for you.

How to Anchor a Pontoon on a Sandbar

  1. Approach slow. Idle in, watch the bottom color (dark = deeper, light tan = shallow). Pontoons get up on plane quickly. They also stop quickly. Walking pace is the goal once you are inside 50 feet.
  2. Pick your anchor side. Note the wind direction. The boat will pull away from the anchor with the wind, so set the anchor up-wind of where you want the boat to sit.
  3. Drop the bow anchor in the sand. Pay out 3-5 times the water depth in rope (5:1 in current, 3:1 in calm).
  4. Back down to set. Reverse gently for 5 seconds, then idle. Watch the bow swing. If it swings and holds, you are set.
  5. Optional: stern anchor. If you want to keep the boat perfectly parallel to the bar so swimmers can use the ladder safely, drop a second anchor off the stern.

What to Bring

  • Cooler with ice, drinks, and snacks. No ice = warm drinks by 1 PM. Buy a bag at the dock if you forgot.
  • Bluetooth speaker. Available as an OCA add-on if you do not have one.
  • Floats and tubes. Sandbar floating is half the appeal. Inflatables, paddleboards, kid floats. Just bring them.
  • Anchor line buoy (or float marker). Nice-to-have for spotting where the line lies under the water.
  • Sun protection. Hats, reef-safe sunscreen, sun shirts. Pontoons have a Bimini top but the sun off the water is brutal.
  • Trash bag. Pack out everything. This is national seashore.
  • Towels and a dry bag for phones.
  • Snorkel and goggles for the kids. The flats are full of small fish, crabs, and the occasional ray.

A Few Local Tips

  • Look for the parking lot. When you see 5-8 pontoons clustered up on one bar, that is the bar everyone is using. There is usually a reason. Slide in nearby.
  • Or hunt for a private spot. Conversely, if you want privacy, head 10 minutes further south. Sinepuxent is huge and the further you go, the fewer boats you will see.
  • Fishing and crabbing add-ons. OCA rents a fishing package and a crabbing package for $39 each. Sandbar = bait grounds. Easy to throw a line while the kids swim.
  • Sunset bars. The west-facing bay-side sandbars are the spot for a 7 PM sundowner. The sun drops behind the Eastern Shore farmland and the whole bay turns gold.

Pontoon Specs and Capacity

OCA's pontoons accommodate up to 12 guests and rent for 1-8 hours. For sandbar trips, 3-4 hours is the typical sweet spot. You get out to the bar, hang for 2 hours, and have time to swing past wild horses or chase a dolphin pod on the way back.

Book Your Sandbar Day

OCA Watersports pontoons are phone reservation only. Online booking is not available for pontoons. Call 410-629-RIDE (7433) to lock in your time slot and we will run you through the tide chart, the best sandbars for the day you are booking, and any add-ons.

If your crew has thrill-seekers too, book jet skis online and run them alongside the pontoon. Best of both worlds.
