Tugboats (4/8)

A tugboat is a small sturdy and powerful vessel designed to push or tow other vessels and barges

Tenacious tugboat
Tenacious

You will see them in every sizable port; smart, businesslike small ships, low in the water and surging out to a large inbound ship. Tugs represent power for pushing and pulling, an engine with just enough hull for adequate buoyancy. Thick fenders for close-quarters work, pushing a big ship alongside the quay against the wind, hauling her off at the end of a towing wire.

Barnacles

Barnacles are the strangest of crustaceans. Imagine a tiny shrimp glued down by the top of its head, with its antennae waving in the current, and you begin to understand what a barnacle really is.

Northern Rock Barnacles ( Balanus balanoides, to 1" ) grow in the intertidal zone, subtidal in places, attached to any hard surface. They are in constant competition for living space with mussels. Mussels grow faster but are more susceptible to drying out. Therefore, mussels quickly take over the lower wetter areas, while barnacles rule in the higher dryer reaches.
