Tall bow for bad weather, name of boat on bow for commercial boats is required to facilitate VHF calls. Forward pilot house to give more work space on-deck, shallow draft and protected running gear for safely getting into and out of skinny water. This one has a second helm to operate from the business end of the boat. Dry exhaust simplifies things. Bucket over top keeps rainwater out of manifold and cylinders when not underway. In Maine, lobster boats “keel pipes” were common for antifreeze and fresh water cooling. I forgot to note what this boat had for cooling. Note the transom has no “holes” for wet exhaust and cooling water to exit.
