In this article, we will explore the process of blacking a narrowboat hull, from preparation to choosing the right coating. So, if you are a narrowboat owner looking to keep your vessel in top shape, read on for valuable tips and insights.
Key Takeaways:
- Regularly blacking the narrowboat hull is essential for maintenance and rust prevention.
- Preparing the boat for blacking involves removing it from the water.
- There are different methods to remove the boat from the water, including craning and using a slipway trailer or dry dock.
- Two main types of blacking coatings are Bituminous blacking and Two Pack Epoxy blacking, each with their own advantages.
- Blacking can vary in cost depending on factors such as location, coating type, and boat size.
Methods to Remove the Boat from Water
When it comes to blacking a narrowboat hull, the first step is to remove the boat from the water. There are three common methods for accomplishing this: craning, using a slipway trailer, and utilizing a dry dock.
- Craning: This method involves using a large crane to lift the boat out of the water. While craning provides a quick and efficient way of removing the boat, it can be quite expensive.
- Slipway Trailer: A slipway trailer is the most cost-effective option for removing a narrowboat from the water. The boat is driven onto the trailer, which is then pulled out of the water using a vehicle or winch.
- Dry Dock: Utilising a dry dock involves driving the boat into a floating dock and then pumping out the water. This method provides a stable platform for working on the hull. Most people have this sort of hull work carried out in a dry dock.
The choice of method depends on various factors, such as cost, availability, and the specific requirements of the boat owner. While craning may be suitable for those with larger budgets and access to crane facilities, using a slipway trailer or dry dock can be more practical and affordable options for many narrowboat owners.
Some dry docks can also be rented so that DIY maintenance can be carried out by the boat owner. An expert at Portland Basin Marina explains:
“The dry dock is now fully operational and available for hire. It is a covered facility for all weather repairs. It is available for DIY or we can carry out hull blacking or repairs for you.”

Types of Blacking Coatings
When it comes to blacking narrowboat hulls, there are two main types of coatings to consider: Bituminous blacking and Two Pack Epoxy blacking. Each option has its own advantages and considerations, allowing narrowboat owners to choose the best coating for their specific needs.
Bituminous blacking is a popular choice due to its affordability. It is a traditional coating that provides effective protection against rust and corrosion. However, it typically requires more frequent application, lasting around 2-3 years before needing to be reapplied.
Two Pack Epoxy blacking is a more advanced and durable option. While it comes with a higher price tag, it offers superior protection and longevity, lasting around 5-6 years before requiring reapplication. This type of blacking is particularly beneficial for narrowboats that spend a significant amount of time in abrasive or brackish water conditions.
If a narrowboat is already coated with Bituminous blacking and the owner decides to switch to Two Pack Epoxy, it’s important to note that the hull will need to be stripped back to bare steel. This process can be more labour-intensive and costly, but it ensures proper adhesion and the best results with the new coating. I’d always advise the epoxy method if you can afford it – especially if you have no intentions of selling the boat in the next few years.
The Benefits of Bituminous Blacking:
- Cost-effective option.
- Effective protection against rust and corrosion.
The Benefits of Two Pack Epoxy Blacking:
- Long-lasting protection (5-6 years).
- Superior durability, ideal for abrasive or brackish water conditions.
| Coating Type | Duration |
|---|---|
| Bituminous blacking | 2-3 years |
| Two Pack Epoxy blacking | 5-6 years |
Cost of Blacking the Hull of a Narrowboat
The cost of blacking a narrowboat hull can vary depending on several factors. These factors include the location of the boat, the type of coating chosen, and the size of the boat. As a result, the cost of blacking can range from as low as £800 to over £1,500.
It is always a good idea to shop around and compare prices from different providers to ensure you are getting the best value for your money. Keep in mind that while it is technically possible to undertake the blacking process yourself, it is generally recommended to hire professionals, especially if you are inexperienced in the process. This can help ensure a high-quality finish and minimize the risk of mistakes or damage to the hull.
Duration of the Hull Blacking Process
The process of blacking a narrowboat hull typically takes three days to complete. It involves several steps to ensure a thorough and effective coating that protects the hull from rust and damage. Here is an overview of the blacking duration and the tasks involved:
Day 1: Removal and Preparation
On the first day, the boat is removed from the water using one of the common methods such as craning, slipway trailer, or dry dock. Once out of the water, the hull is thoroughly pressure washed to remove any debris, rust, and the previous blacking coating. This step is essential to create a clean and smooth surface for the new coating.
Days 2 and 3: Coating Application
On the second and third days, the new blacking coating is applied to the hull. This is done by hand using a roller to ensure an even and comprehensive coverage. The choice of coating, whether bituminous blacking or two pack epoxy blacking, depends on factors such as budget and duration of protection desired. The coating is carefully applied to every inch of the hull, including hard-to-reach areas.
48 Hours Drying Time
After the coating has been applied, it is crucial to allow the hull to dry for a minimum of 48 hours. This drying time ensures that the coating sets properly and provides optimal protection against rust and corrosion. It is important to resist the temptation to rush the process and return the boat to the water before the recommended drying period.
By following this three-day blacking process, narrowboat owners can ensure that their boat’s hull is well-protected and maintained for years to come. The effort put into this essential maintenance task is well worth it to preserve the integrity and appearance of the narrowboat.
Maintaining the Boat Hull Coating After Blacking
Once the narrowboat hull has been blacked, proper maintenance is crucial to ensure its long-term protection and overall care. By following a few key practices, narrowboat owners can keep their hulls in excellent condition and avoid costly repairs.
Careful Cruising
One of the most important aspects of hull maintenance is practicing careful cruising. This means avoiding actions that can damage the hull, such as breaking through ice or crashing into banks and locks. By navigating with caution and being mindful of potential hazards, owners can prevent unnecessary wear and tear on their narrowboat hull.
Regular Inspection of Sacrificial Anodes
Sacrificial anodes play a crucial role in protecting the narrowboat hull against corrosion. These specially designed metallic devices sacrifice themselves by corroding instead of the hull. Regularly inspecting the sacrificial anodes is essential to ensure they are in good working condition. Look for signs of pitting and corrosion, as these indicate that the anodes are actively protecting the hull. If any issues are detected, replace the anodes promptly to maintain effective corrosion protection.
| Anode Type | Expected Lifespan | Price Range (per anode) |
|---|---|---|
| Zinc Anodes | 1-2 years | £10-£30 |
| Aluminium Anodes | 3-4 years | £15-£40 |
| Magnesium Anodes | 5-7 years | £20-£50 |

Regular Maintenance Checks
In addition to inspecting sacrificial anodes, regular maintenance checks should be conducted to keep the narrowboat hull in optimal condition. This includes examining the hull for signs of damage, such as scratches or dents, and promptly addressing any issues. It is also important to perform routine cleaning to remove dirt, algae, and other debris that can accumulate on the hull.
“Regularly checking the sacrificial anodes and conducting maintenance checks can go a long way in preserving the integrity of the narrowboat hull and preventing expensive repairs in the future.” – Mark Thompson, Narrowboat Owner
By following these maintenance practices, narrowboat owners can enjoy their vessels for many years to come. Taking proper care of the hull after blacking ensures its longevity and can save significant costs down the line.
