The Great Loop
Challenge 2026

The Great Loop is a continuous circuit of eastern North America: up the Atlantic seaboard, through the Great Lakes, down the inland rivers, and back around Florida.

On 8 August 2026, Captain Scott “Red” Flowers took on the challenge, rallying supporters to help fund safer, more effective treatments for children battling cancer.

Hefring’s IMAS is one of those ‘don’t leave it on the dock’ products. It will become your best friend.

IMAS gave me a huge sense of peace out there, knowing I had another set of eyes with me. The system was always spot on, and it was amazing how accurate it was about the sea conditions ahead.
