At 20 mph, the trip is roughly 21.4 minutes per nautical mile of distance, so the exact time depends on the route distance you’re using. A nearby public boating listing shows Wacca Wache Marina is 7.14 miles from Bucksport in one directory context, which works out to about 21 minutes at 20 mph.

Estimate

  • 7.14 miles ÷ 20 mph = 0.357 hours
  • 0.357 hours × 60 = about 21.4 minutes

Practical range

On the water, the real trip can take a bit longer because of:

  • no-wake zones,
  • turns in the river,
  • current and wind,
  • slower actual cruising speed than the headline number.

So a fair real-world estimate is about 20–25 minutes , with ~21 minutes as the straight-speed math.

Route note

Wacca Wache Marina is on the Waccamaw River / AIWW in Murrells Inlet, which helps explain why the route can vary by exact marina slip and river conditions.
