All newsSpring is just around the corner, and that means one thing for boaters—it’s time to get back on the water! But before you set sail, there’s a crucial process that Northern, Midwestern, and Mid-Atlantic boaters must complete: spring commissioning.
We talked to John Staub, Director of Service at Diversified Marine Services, to walk us through everything you need to know about preparing your boat for the season. From critical safety checks to common mistakes to avoid, this guide will help you kick off spring the right way.
What is Spring Commissioning?
Spring commissioning is the process of preparing your boat for the upcoming season after winter storage. This includes:
✅ System checks to ensure everything is running properly
✅ Routine maintenance to prevent unexpected breakdowns
✅ Safety inspections to keep you and your passengers safe
✅ Cleaning & detailing to protect and extend the life of your boat
Even if your boat was properly winterized, small issues can arise over the off-season, and the last thing you want is to launch your boat, only to find out it won’t start.
3 Key Components of Spring Commissioning
John shared the top three things that every boater should focus on during commissioning:
1. Know Your Limits
Don’t be afraid to ask for help! Boating is all about learning and growing—whether you’re a seasoned captain or a weekend warrior. If something is out of your expertise, consult a professional technician to avoid costly mistakes.
2. Inspect Your Safety Systems
Make sure your bilge pumps, navigation lights, and radios are in working order. John noted that improperly wired bilge pumps cause multiple boats to sink every year! A quick safety check can save you from a major disaster.
3. Get Familiar with Your Operating Systems
Before heading out on the water, check the essentials:
✔️ Engine fluids (oil, coolant, fuel)
✔️ Battery health & connections
✔️ Seawater flow for cooling systems
✔️ Fuel and plumbing lines for leaks
✔️ Rigging and running gear (for sailboats)
When Should You Start Spring Commissioning?
As early as possible!
John recommends starting 4-6 weeks before your first planned outing. This gives you enough time to troubleshoot issues and avoid last-minute delays.
While some boaters try to commission their boats in early March, keep in mind that:
- Cold temperatures below 50°F can impact waxing, painting, and curing processes.
- Last-minute service requests can be delayed if technicians are already booked.
If you plan ahead, you’ll avoid the mid-season rush and costly expedited services.
How Spring Commissioning Affects Boat Performance
A well-commissioned boat isn’t just safer—it also runs more efficiently.
Proper maintenance reduces wear and tear on systems, minimizing failures and keeping you on the water longer.
Some of the biggest performance issues John sees are caused by small, overlooked details:
- Dirty fuel filters leading to engine failure
- Clogged seawater intakes causing overheating
- Loose hoses popping off at the worst possible time
- Fouled hulls affecting speed and fuel efficiency
A little pre-season care can save you big headaches down the line.
Step-by-Step Spring Commissioning Checklist
John recommends a top-down approach when commissioning a boat.
1️⃣ Electrical & Battery Systems
Check battery health & charge level
Test all electrical components (lights, bilge pumps, radios)
2️⃣ Engine & Propulsion Systems
Check engine fluids & replace filters
Confirm water flow for cooling system
3️⃣ Fuel & Plumbing Systems
Inspect fuel lines for leaks
Flush water systems & test for pressure
4️⃣ Safety Equipment & Navigation
Inspect life jackets, flares, fire extinguishers
Ensure navigation & communication systems are working
5️⃣ Hull, Deck & Rigging (For Sailboats)
Clean, wax & apply anti-fouling paint if needed
Check standing & running rigging for wear
Common Mistakes to Avoid
🚨 Rushing Through the Process
🚨 Forgetting the Drain Plug
🚨 Ignoring Stuffing Boxes & Seacocks
🚨 Neglecting Fuel Quality
🚨 Skipping Battery Tests

Why Spring Commissioning Matters
Proper maintenance isn’t just about convenience—it’s about safety.
A poorly maintained boat can lead to dangerous situations, like:
Onboard fires due to electrical failures
Fuel system leaks causing engine shutdowns
Losing propulsion in the middle of a busy waterway
In Maryland alone, the Coast Guard reported 123 boating accidents, 49 injuries, and 6 fatalities last year. Many of these could have been prevented with proper maintenance.
