Having said that, we’re assuming readers of this article aspire to a reasonable level of comfort as opposed to camping on the sea.

Envoy’s master bedroom – we don’t just camp on the sea but live rather well aboard

A live-aboard vessel often cruises beyond the easy reach of regular service and spare parts providers and bearing in mind the boating adage that everything that can go wrong will eventually go wrong she needs to be engineered for maximum reliability with redundancy of systems and a well-planned inventory of chandlery, tools, key spare parts as well as an operation manual and documentation covering equipment carried aboard. Even if (like me) you’re not an engineer, you can generally get assistance with problems if you have the necessary tools, parts and information.

Fuel supply
Most diesel engine problems are fuel-related so this is an area to pay particular attention. Boats have a primary (before engine) fuel filter, and a secondary (on engine) filter. You can enhance this by having a system for filtering (or “polishing”) fuel into one tank (often known as a “day tank”) which will then supply the primary filter(s) and run the engine(s). This tank is kept reasonably full from the storage tanks using the polishing system and also accepts the filtered return fuel from the engine(s).
Envoy for example has a Racor-based polishing system which filters about 10 litres/minute through a 2 micron cartridge and in 10 years of ownership we’ve not encountered any kind of fuel contamination.
Large capacity dual primary filters able to be interchanged under way and fitted with a vacuum gauge and moisture detector will also help minimise problems.
Fuel tanks should have generous-sized removable inspection ports to allow periodic cleaning if required.

Electrical
A generator is desirable so that power is available when anchored for long periods.
The house battery bank should be deep cycle with sufficient amp hour capacity for the equipment carried. The start bank should not be deep cycle and dedicated to starting the engines. Both banks should have isolating switches and the banks should be connectable using a parallel switch in case of low voltage in the start bank.
All circuits should be protected using circuit breakers. Having an electrical circuit diagram is a big advantage.
Other desirable equipment is a high capacity engine alternator with a “smart” regulating system, a battery charger able to operate from both generator and shorepower and an inverter to produce AC from the house bank.

Ground tackle
To anchor in remote areas, sometimes in adverse weather it’s essential to have a main anchor, spare anchors, all-chain rode and windlass appropriate to the size of vessel with a minimum of 100 metres of chain. Do not compromise in this area.

Water and sewage
Potable water is often not readily available overseas so ample fresh water storage is required, preferably in more than one tank. Sewage holding tanks are essential and it’s a good idea to have a diverting valve on your head which can either discharge sewage directly into the sea when well offshore, or into the holding tank when close to shore.

Galley
 A stove with at least three burners is desirable together with a medium sized oven. We prefer lpg to electric so that we don’t need to run a generator to use the stove. Diane says our microwave is nice to have, but not necessary.

Refrigeration
An effective high storage capacity refrigerator and freezer is essential – you’ve got to keep the beer cold! I don’t advocate refrigeration powered solely from the house battery as refrigeration generally causes by far the largest current draw and these systems are always chasing battery charge. Our system uses AC from the generator.

Stabilisation
Stabilisers are highly desirable for a displacement monohull vessel and we recommend as a minimum having paravane (passive) stabilisers. Although these are not pretty they are very robust and reliable and with this system you can also use flopper-stoppers to reduce roll when anchored. Hydraulic (active) stabilisers are more effective, but expensive to maintain and prone to occasional failure while most hydraulic systems don’t help at anchor. Envoy has both of these systems.
Gyro systems are also highly effective, but less common and generally found on larger vessels.

Safety equipment
Of course you must ensure the vessel has, or will be equipped with all obvious safety equipment including an approved self-inflating liferaft if venturing offshore.

Tender
Many live-aboard vessels have large heavy tenders, which are only able to be launched or retrieved in calm conditions using a boom winch or a hoist. Our 3.7m RHIB with 25hp outboard is excellent, but we also value our much lighter 2.7m RHIB with a 2.3hp outboard, able to be launched by hand. Remember that for most coastal cruising vessels the tender is the liferaft so should be well-equipped and easily launched.

Your tender generally doubles as liferaft in coastal cruising – we carry two

Air conditioning and heating
Although Envoy has reverse cycle air conditioning we rarely use it as to work effectively all doors, windows and portholes need to be closed and the engine or generator needs to be running. Heating options need to be considered if wintering afloat in cold conditions.

Laundry
It’s so inconvenient and expensive to get laundry done when cruising that we regard a washing machine as essential. It will soon pay for itself in saved laundry costs and remember that the first mate has to be happy too!

Surveying your vessel and final negotiations
Unless you are a boat builder or similarly qualified it’s essential to engage a qualified surveyor (who acts for and is paid by the buyer). This applies to all pre-owned vessels, but should also be considered for new vessels as these are not immune from poor practice. Surveyors not only have considerable technical expertise, but follow a logical documented process for a thorough examination of the vessel and are totally objective whereas the excited buyer might overlook or downplay some negative issues. A recent survey is also helpful when insuring your vessel.

Now enjoy your vessel
Before heading to sea for the first time spend a few days thoroughly familiarising yourselves with your vessel. Know where all equipment is stowed, how it works, where the different seacocks are etc.
