Right boat vs Wrong boat – Over 30 Ways to Cut the Cost of Your Sailing and Cruising
Sailing and cruising offer unparalleled freedom and adventure, but they can quickly become costly. Fortunately, there are numerous strategies to help you enjoy the open water without breaking the bank. Here are over 30 practical ways to cut your sailing and cruising costs.
Anchoring – getting it right
Boat interior inspection and checks
While a boat is ashore, the most critical interior checks to carry out are those that concern the safety of the boat. This entails the integrity of all through-hull fittings and seacocks, the gas system and the electrical system.
Narrowboating on the Kennet and Avon Canal
A recently cancelled sailing event I was due to take part in left us with a free weekend in the diary. Given that my wife and I were celebrating a bumper wedding anniversary and the weather forecast was for fine weather, we decided to hunt around for a last minute canal holiday.
Propeller care and maintenance
Propellers are complicated and repairs should be done by specialists but owners can carry out checks and some routine maintenance themselves when the boat is in the boatyard. A propeller is critical to a boat’s performance, fuel consumption and ride, so it makes sense to keep a propeller in good working order.

Have a look around any boatyard and you will notice quite a variety of propellers – some have two blades, some have three and others have four or more. While most propellers are completely rigid some have blades that fold.
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 “rules of the road” for boats. Some key concepts within the COLREGs include:
Pleasure craft safety equipment recommendations
Engine failure at sea – common causes and how to avoid them
Many engine failures are caused by lack of maintenance, resulting in fuel filter blockages, water pump failures, overheating and other breakdowns. Indeed, one of the most common reasons for marine rescue service call outs is for one of the most basic reasons possible – boats that have run out of fuel.
Tips and advice for staying safe on a sailboat at sea

Keel maintenance and Repair – Part 2
If you have ever witnessed a boat colliding with a rock or other submerged obstacle you will know that there is an almighty thump and the whole boat shakes and judders. While such hard groundings seldom result in catastrophic keel failure, something has to give and even the sturdiest keels can easily be damaged by such an impact.
