Boating hazards are a major concern for anyone who takes to the water. WHIRLPOOLS, which are 10 letters long, are powerful currents of water that can pull boats and swimmers down into the depths. Reefs, which are 5 letters long, are shallow areas of water with rocks or coral that can cause damage to boats. SHOALS, which are 6 letters long, are shallow areas of water that can be difficult to navigate. SNAGS, which are 5 letters long, are submerged objects such as logs or branches that can cause damage to boats. All of these hazards can be dangerous for boaters and should be avoided.
