Hey folks, if you’ve ever wondered why some work boats look like they need a small village to run them while others feel like you could count the crew on one hand, you’re not alone. As someone who’s spent the last decade selling work boats (and all the gear that keeps them running smooth), this is one of the most common questions I get from new operators—whether they’re just starting out with a single tug or scaling up their offshore fleet. Today, I’m breaking down the typical crew sizes for the most common work boat types, why they vary so much, and what that actually means for your bottom line. No stuffy industry jargon, just real talk from someone who’s seen it all. Work Boats
First off, let’s get one thing straight: there’s no one-size-fits-all number here. A lot of people think it’s just “x number of people per boat” but it’s way more nuanced. It depends on the boat’s job, size, operating environment, and even the local safety rules (yeah, different countries have different requirements, but we’ll stick to North American and international standards since that’s most of what I deal with). Let’s run through the big work boat categories one by one, starting with the smallest and moving up, because that’s how most operators start their fleets.
Let’s kick things off with the work boat you probably see every day if you live near a harbor: the simple utility work boat. These are the guys doing the small jobs—checking mooring lines, picking up debris from the water, moving supplies around a port, or helping small ships maneuver. I’m talking 20 to 40 footers, right? For these, the typical crew size is 1 to 2 people. Wait, let me clarify: most 20 to 30 foot ones run solo. The skipper does everything—drives the boat, handles the lines, checks the equipment, even grabs a coffee mid-shift. They’re small enough that one person can manage all the tasks, and port rules don’t require extra hands here. Move up to the 30 to 40 foot utility boats, and you might add a deckhand. Why? Because the jobs get a little more demanding—like lifting a crate of supplies from a dock to a ship, or pulling a big piece of debris that’s wedged under a pier. You need an extra set of hands to handle the winch or hold lines steady. I recently sold a 35-foot utility boat to a port in Maine, and they run it with a skipper and one deckhand. Works perfectly for their daily tasks of moving parts for their ferry fleet and maintaining the harbor. No need for extra people there.
Next up, tugs. Tugs are the workhorses of the maritime industry—they push and pull big container ships, tankers, and even offshore rigs in and out of harbors. This is where crew sizes start to shift a bit, and it’s mostly about how powerful the tug is. Small harbor tugs, the ones you see zipping around ports with a big container ship, are usually 60 to 80 feet long. Their typical crew is 3 to 4 people. Let’s break that down: you need a master (the skipper in charge), a pilot who’s super familiar with the harbor’s currents and obstacles, and two deckhands. Wait, some smaller harbor tugs might run with 2 if it’s a really tight, well-known port, but that’s rare these days because safety rules have gotten stricter. Move up to ocean-going tugs, the ones that travel hundreds of miles with a drilling rig or a broken-down cargo ship? Those are way bigger—100 to 200+ feet. Their crew size jumps to 8 to 12 people. Why? Because they’re out at sea for weeks at a time, so you need full shifts to operate around the clock. You’ve got the master, a chief engineer, two or three licensed officers, two or three ratings (deckhands), a few engine room guys, and sometimes a cook too. Oh right, living on a tug for two weeks means someone’s got to make the meals. I had a customer last year who bought a 150-foot ocean tug to service offshore wind farms, and they run it with 10 people. That works for 21-day stints out at sea, no issues.
Now let’s talk about offshore work boats, specifically the ones that support oil and gas or wind farm operations. These are a whole different ballgame because they’re working in open water, far from shore, and dealing with heavy equipment. Let’s start with the service crew boats, the ones that transport workers and supplies to offshore rigs or wind turbines. The smaller ones, 80 to 100 feet, usually run with a crew of 2 to 3: a master and one or two deckhands who handle the transfer of people via the gangway or crane. The bigger service boats, the ones that carry heavy cargo (like wind turbine blades or generators) out to the farm, are 120 to 180 feet, and their crew goes up to 4 to 6. You need extra hands to secure the heavy cargo, operate deck cranes, and monitor weather conditions. Then there are the specialized boats, like the crew transfer vessels (CTVs) that are all the rage for offshore wind these days. CTVs are designed to zip fast between the shore and wind turbines, and their typical crew is 2: a master and a deckhand who handles the personnel transfer equipment. That’s it? Yep, because CTVs are super automated now, so you don’t need a big crew. I’ve sold a bunch of CTVs to wind farm operators in the UK and the US, and they stick to that 2-person crew—it’s efficient and meets all safety rules.
Wait, what about rescue work boats? Those are the ones that go out during storms to pull people from sinking ships. They’re built tough, and their crew size is usually 2 to 4. A rescue skipper, a medical technician (super important if they’re picking up injured people), and one or two deckhands to handle the rescue gear like lifeboats or winches. I work with a few coast guard auxiliaries who run small rescue boats, and they use 2 people, which works for their local, near-shore missions.
Now, let’s get into why all this matters for you, not just random numbers. As someone who sells work boats, I always tell customers to think beyond just the initial cost of the boat. Crew size directly impacts your operating expenses. More crew means more salaries, more training, more benefits. If you’re running a small harbor utility boat with 1 person vs 2, that’s thousands of dollars a year you’re saving. But wait, you don’t want to cut corners on safety either. A lot of new operators try to run a 80-foot harbor tug with 2 people to save money, but that’s a recipe for burnout and accidents. The rules are there for a reason—if your boat is big enough to require 4 people, you can’t just run with 2, because each role is critical during a job like maneuvering a giant tanker.
I’ve seen this play out first-hand. A few years back, I sold a 70-foot tug to a small company in the Pacific Northwest. They initially tried to run it with 2 people, figuring they’d save cash. But after a couple of close calls—one where they almost lost control of a cargo ship because they were short a deckhand to handle the bow line—they hired a third. They still saved money compared to running a bigger tug with 4 people, and their insurance rates even went down because their safety record improved. That’s the kind of real-world stuff I don’t see in industry manuals.
Another thing that affects crew size: automation. A lot of newer work boats have GPS for docking, automated winches, and even remote monitoring for engine rooms. That cuts down on the number of people you need. Ten years ago, a 100-foot ocean tug would have a crew of 12, now you can get away with 9 or 10 because of automated systems. But you still need people to manage those systems, right? Automation doesn’t replace skilled workers—it just changes what their jobs are.
Also, operating environment. If you’re working in a place with super harsh weather—like the North Sea or the Gulf of Alaska—you need extra hands to handle bad conditions. Not just for safety, but because the jobs are more physically demanding. If a wave hits your deck, you need four people instead of two to secure gear. Work in calm, sheltered harbors? You can get away with smaller crews.
Wait, let’s wrap this up with some quick takeaways, because I know you’re busy. First, small harbor utility boats (20-40ft): 1-2 crew. Small harbor tugs (60-80ft): 3-4 crew. Ocean-going tugs (100+ft): 8-12 crew. Service supply boats (80-180ft): 2-6 crew. CTVs for wind farms: 2 crew. Rescue work boats: 2-4 crew. These are typical, but always check your local maritime safety regulations—different countries have different rules, and different jobs can adjust numbers a little.
At the end of the day, the right crew size is all about balancing safety, efficiency, and your specific needs. If you’re new to work boats and trying to figure out what size vessel fits your operation—and how many people you actually need to run it—hit me up. I’ve helped dozens of operators pick the right boat with the right crew setup, so they don’t waste money or run into safety headaches. I’m always here to chat, no sales pitch pressure unless you want it. Just send a note, and we can work through what works for your port, your jobs, and your budget.
