Your boat was considerably larger than the skiff they just completed

the harbors on Long Island Sound that I am most familiar with, they
use a different technique and smaller boats. They'll typically rig a
steadying sail to help them maintain position while working a rake or
basket on the end of a very long pole.

That sounds like a skipjack.

Skipjack use a dredge commonly called a scrape, and tow them across oyster beds.

If I recall correctly they also carried a small power skiff on davits and used it only on certain days to push the skipjack towing the dredge.

My Dad's friend Bill? Richardson used to build Skipjacks on the Choptank? river near Cambridge MD.
