Part 1 - How to start a Boat Winterization business - Background
Many boat owners have their boat taken out of the water and put into storage at season’s end. Before a boat can safely be stored for the offseason, however, it must be winterized. Winterization is the process of cleaning a boat, servicing its engines and systems, and covering the boat.
While some boat owners winterize their vessels themselves, many hire a business to do the work. Boaters may choose to have a business service their boat because they don’t have time to do it themselves, they don’t want to do it themselves, or they want other maintenance items checked at the end of the boating season.
Our guide is in 3 parts:

- Part 2 - Our planner tool to see if this idea is the right fit for you
- Part 3 - Action plan to get started
What are the costs involved in opening a boat winterization business?
The startup costs for a boat winterization business are minimal. Business owners need:
-
Basic tools
-
A power washer
-
Fuel stabilizers, antifreeze, and similar fluids
-
Shrink wrap
-
Specialized shrink-wrapping tools
Business owners who have little initial capital can begin by borrowing tools if they don’t have the required ones already, and a power washer can be borrowed or rented as needed. The required fluids don’t cost much. Boating places the cost of taking care of fluids between $50 and $110.
The largest expense is usually the cost of shrink wrap and the specialized tools needed to apply it. Michael Enos spend $2,000 on shrink wrap and tools when winterizing his first boat (which was his personal airboat).
Business owners can save on building expenses by going to a client’s site rather than purchasing or leasing a work area. The tools and equipment will fit in any car, truck, or SUV, so it’s easy to offer services on-site.
What are the ongoing expenses for a boat winterization business?
The ongoing expenses for a boat winterization business are low. Business owners need to purchase supplies as they use fluids and shrink wrap. Those that have employees must pay salaries and any commercial space that’s used must be paid for.
Who is the target market?
Boat owners are the target market for a boat winterization business. Anyone who has a boat that’s larger than a dinghy, canoe, or kayak may need their boat winterized.
How does a boat winterization business make money?
A boat winterization business makes money by charging customers for winterizing their boats. Whether boat owners do any of the above-listed work themselves can affect how much is charged.
How much can you charge customers?
The average amount charged to winterize a boat is $300. Smaller outboards can be as little as $100, while cabin cruisers can run $600 or more.
The fees charged by Sportsman’s Boat Storage shows how the cost to winterize different boats can vary. The storage center offers winterization starting at $250. Additional fees are charged for extra services, such as:
-
Changing oil ($75 to $110)
-
Winterizing a freshwater or porta potty system (cost varies)
-
Winterizing a ballast system ($50 per pump)
-
Adding a fuel stabilizer ($14.21 average)
How much profit can a boat winterization business make?
With an average price of $300, a boat winterization business can bring in a substantial seasonal profit. Winterizing just two boats a day could result in a daily revenue of $600 throughout the fall.
How can you make your business more profitable?
Many boat winterization businesses also offer basic small boat repairs. To add repair services, business owners should take a marine engine repair course. Annapolis School of Seamanship, Universal Technical Institute, and many other schools offer classes.
Day-to-Day and Growth
What happens during a typical day at a boat winterization business?
Winterizing a boat typically takes a few hours. The exact work done depends on the type of boat being winterized, but it usually involves the following:
-
Pulling the boat out of the water (if not previously done)
-
Cleaning the boat (possibly power-washing or polishing it)
-
Draining some of the fluids in the engine
-
Adding stabilizers and/or antifreeze to the engine fluids that are left
-
Servicing the other fluid and electrical systems on board
-
Covering the boat in shrink wrap
-
Placing the boat in storage (either inside or outside)
This work may be performed in an indoor workspace, outside, or at a customer’s location.
What are some skills and experiences that will help you build a successful boat winterization business?
At the very least, business owners must know how to winterize many different types of boats. Customers will have inboards, outboards, inboard/outboards, sailboats, and wooden boats, each with slightly different needs.
To learn how to winterize different boats, prospective business owners should spend a season working at a marina that offers winterization services. There are a number of free guides on boat winterization, but these are better used as references than training materials. They don’t cover everything that business owners may encounter. (Boat U.S. is a well-known organization that has published a thorough guide.)
What is the growth potential for a boat winterization business?
Most boat winterization businesses are small, local operations. For example, Mike’s Marine Service is a typical marina that offers winterization and other services.
Businesses that expand beyond a defined region usually focus on a single aspect of winterization — shrink-wrapping — and offer the service for more than just boats. This is what Michael Enos did with Fast Wrap, a business that grew to dozens of locations by offering shrink-wrapping service for boats, amusement park rides, and other winterized equipment.
What are some insider tips for jump starting a boat winterization business?
Going to customers’ locations has several benefits beyond merely keeping startup costs low. By not procuring a specific workspace, business owners:
-
Keep their overhead low, which allows them to undercut the competition
-
Offer a more convenient service, which can become a major selling point
-
Make themselves visible in boating areas, which leads to an increased number of clients
How and when to build a team
Many business owners start out by themselves and a number never hire employees. Those who do want to grow the business usually bring on seasonal workers to help meet the demand in fall. Having at least one employee also makes shrink-wrapping boats go much faster.

Part 3 - Action plan to launch your Boat Winterization business in 90 days
Nine concrete steps to take you from idea to open business, grouped into 30-day phases. Complete the planner above and we'll highlight what's most important for your situation.
First 30 days — Foundation
-
Form your legal entity
An LLC keeps your personal assets separate from business debts and lawsuits — the most common reason small business owners choose this structure. Sole proprietorships and partnerships do not provide this protection.
-
Get an EIN and register for taxes
Apply for your free Employer Identification Number through the IRS, then register for any state or local taxes that apply to your business (sales tax, franchise tax).
-
Open a business bank account and credit card
A dedicated business account is required to maintain personal asset protection. Mixing personal and business finances ('piercing the corporate veil') can void your LLC's liability shield.
-
Set up business accounting
Recording expenses and income from day one makes tax filing easier and lets you see when the business is actually profitable. Use software (QuickBooks, Wave) or a part-time bookkeeper.
Days 30–60 — Compliance & Risk
-
Get permits and licenses
State and local requirements vary widely. Brick-and-mortar businesses typically need a Certificate of Occupancy; service businesses may need specific professional licensing; food businesses need health permits.
-
Get business insurance
General Liability Insurance is the most common starting point. If you'll have employees, most states require Workers' Compensation. Specific industries need additional coverage (product liability, professional liability, etc.).
Days 60–90 — Launch
-
Define your brand
Your brand is how customers perceive and remember you. A clear name, logo, and visual identity make every later marketing decision easier and protect you legally as you grow.
-
Create your business website
Every legitimate business needs a website. Social media pages are not a substitute — you don't own the platform. Modern website builders mean you can launch a clean site in a weekend without a developer.
-
Set up your business phone system
A dedicated business number keeps your personal life private, makes the business look legitimate, and lets you route calls professionally. Cloud phone services start under $20/month.
