How to read nautical charts
by Simon Jollands | Crewing skills, Navigation, Preparation
Whilst most sailors today rely on GPS to find their way at sea, nautical charts are a crucial tool for any sailor to navigate safely and effectively. Here is a reminder of some of the basic steps involved in reading a nautical chart:
Learning about diesel engine maintenance
by Safe Skipper | Boat Maintenance, Preparation, Yacht ownership
Marine diesel engines are internal combustion engines that are designed specifically for use in maritime applications. These engines are commonly used in a variety of watercraft, ranging from small boats and yachts to large ships and vessels. Learn about marine diesel engine maintenance courses.

Boat Handling – anchoring
Wooden Hulls – Part 2
It is important to ensure the essential hull maintenance of a wooden boat is done, even if you are paying others to look after your boat for you. The priority is to prevent rot from taking hold. The protective layers of paint and varnish over wood are far more critical than on GRP boats, where the topsides are painted more for cosmetic reasons.

Top Tips For Learning: ColRegs Boating Rules Of The Road
Colregs Boating Rules Of The Road
The International Regulations for Preventing Collisions at Sea (COLREGs) are a set of rules designed to prevent collisions between vessels. They are essentially the ārules of the roadā for boats. Some key concepts within the COLREGs include:
Sail care and maintenance – Part 1
When thinking about the care, maintenance and repair of sails it helps to have some understanding of the properties of the ever growing range of modern sailcloth and the fibres they are made from, as opposed to the traditional canvas sails of the past.

Boat engine cooling systems
Some boat engine breakdowns are unavoidable but those caused by lack of maintenance or regular checks can be avoided. Failure to maintain an engine’s cooling system is a well known example of this, so it is well worth spending time checking over the cooling system both when the boat is ashore and afloat.
The dangers of running aground in a motor boat
The peril of grounding a motor boat is not only an inconvenience; it can lead to substantial risks for both the vessel and its passengers. . In this article, we’ll explore the potential dangers of running aground and highlight the importance of proper navigation and preparedness to avoid these hazards!
Fractures, sprains and dislocations at sea
Moving about a boat at sea often results in a few knocks and bruises, but if a crew member has a fall or major bump and is in serious pain, they should be examined and treated accordingly.
Tidal terms and definitions
Getting to grips with tidal terms and definitions can seem a little daunting, even to the most experienced sailors! Here we look at some of the key terms and definitions associated with the language of tides.
Boat ownership – some fundamentals
Owning a boat is a big commitment that should bring no end of satisfaction, but the costs of maintaining and keeping a boat are significant and should never be underestimated.
Engine failure at sea – keeping the boat safe
If the engine stops when you are underway, or your have to shut it down when a warning buzzer sounds, you also need to make sure the boat remains safe. Itās important therefore to recognise situations in which the boat would be immediately put in danger if the engine were to fail.
Sending distress signals
In an emergency situation at sea, it is a top priority is to know how to send and receive emergency radio calls and alert others of your predicament. Likewise, if you receive a distress signal, you must be ready to go to the help of others.
Nautical paper charts – a reminder of the basics
The nautical chart is an indispensable tool for navigation. A chart is a graphic representation of an area of the sea which might also include coastlines, estuaries and islands. All cruising leisure boats should carry up-to-date paper charts.

Keeping boat records and doing checks
A boat’s records should provide information about maintenance schedules, when major work was done and when equipment was replaced or added to the boat. Without this information you are left guessing when things are likely to need replacing in the future and also what the costs are likely to be.
Boat interior varnishing
Most boat interiors have a combination of varnished and painted surfaces including solid wooden joinery, plywood laminates with thin hardwood veneers and glass reinforced plastic. When making your assessment of what you are going to do, bear in mind that the varnishing process consumes a lot of time, especially if the existing surfaces are in poor shape.
Boat engine fuel system
If engines are installed and serviced correctly then most marine engines are very reliable, but one of the most important parts of the engine to check and service is the fuel system.

In the third of our three blog articles on rudders and steering systems, we look at how to replace rudder bearings and repair a water-saturated core.
Steel and Aluminium Hulls
The two metals used for hull construction are steel and aluminium. These are both very strong materials and will last a long time as long as they are cared for, which primarily means protecting steel boats from rust and aluminium boats from electrolytic action.
How to use tides and currents to your advantage
If you are contemplating a cruise through tidal waters and strong currents, then planning your trip carefully in advance is essential to enable you to take advantage of favourable tides rather than constantly fighting against them.
Is Boating Good for Your Health and Happiness?
Care of boat batteries
Boat batteries need to be kept properly charged, which means never allowing the batteries to discharge below 50 per cent of their total charge. As well as the batteries themselves, keeping a boat’s charging systems in good shape will also help to keep batteries topped up to a higher level of charge.

Common marine electrical problems
Most problems with marine electrical systems arise from four possible sources, a lack of maintenance, a poor standard of initial installation, insufficient battery capacity, or ineffective charging systems.
Water ingress is a frequent issue ā salt water can corrode contacts very quickly. If connections are not scrupulously clean ā or are loose ā resistance will be increased, resulting in progressively reduced power.
Navigating narrow channels
Navigating narrow channels can present challenges for boat operators due to limited space, restricted manoeuvrability, and potential hazards such as shallows, rocks, or other vessels. To ensure safe passage through narrow channels, itās essential to follow specific strategies and techniques.
