Grounded in sandy mud, super sticking, 50 minute exercised speed up to 4 minutes.

Equipment Used: 3000lb electric winch attached to the front of the boat, connected to a Ground/Sand Anchor, winch powered by 14.8v 4s Lipo Battery, 7000MAH, I have 2x of these, and used all the capacity of one and about half of the second one.

Key Lessons Learnt: Don't drag it to a launch point that is 50/50 - relax go for a walk, find the best route out and drag the boat directly there.
