Biscuit On The Move

Follow our travel adventures aboard M/V Biscuit, a 1989 42 Grand Banks Classic Trawler, Hull #1081.

Day 105 (8/4/26) – Safe Harbor Charleston City Marina to Harborwalk Marina (Georgetown, South Carolina)

Early morning view of Charleston Harbor with Fort Sumter on the horizon.
Early morning departure from Charleston.
Not drunk. Just calibrating the compass!
More dolphin shenanigans! You can see a little of the pink underbelly. Dolphin’s bellies turn pink due to vasodilation, a process where blood vessels near the skin widen to release excess body heat. This happens when dolphins are very active or when swimming in warm summer water, functioning much like a human blush!
This large American alligator crossed our bow and then realized we were there. I think he gave me the evil eye!
A collection of purple martin houses.
Typical waterway scene along the AICW.
Biscuit at rest at Harborwalk Marina.
Boat trivia: these are a few of the zinc anodes that we removed from the propeller shafts yesterday.
The purpose of a zinc anode is to act as a sacrificial metal that prevents galvanic corrosion on vital underwater boat parts, ship hulls, and marine engines. By corroding itself away first, it safely draws destructive electrical currents away from expensive metal components like bronze propellers and steel shafts.
Here’s what zinc anodes looks like new.

Today’s highlights include lots of dolphins and three American alligator sightings! Pretty big ones, too. We also saw three belted kingfishers. Oh, and more wood storks. My binoculars got a workout!

The morning started off rainy and cool as we said goodbye to Charleston. We calibrated the compass on our Garmin GHC 50 autopilot and got it working again. The autopilot is super helpful when we’re cruising, especially for the long straight runs. We had a lovely scenic cruise through the salt marshes to Georgetown, the third oldest city in South Carolina (behind Beaufort and Charleston). We’ll spend tomorrow exploring this sleepy little town. Until next time – sweet dreams!
