Yacht electrical, energy and maintenance guides based on the experience we have gained on the water in Turgutreis and Bodrum.
On the Aslan Yacht blog we write up the experience we have gained on the water over the years around Turgutreis and the Bodrum peninsula. From switching to lithium batteries and connecting shore power to setting up NMEA 2000 networks, servicing Seakeeper stabilizers, flushing watermaker membranes and preparing a boat for winter, we cover the topics that motor and sailing yacht owners, captains and yacht managers actually run into.
In every article we put concrete technical information first: correct voltage values, cable sizing, fuse selection, maintenance intervals and fault symptoms. Our aim is to help owners understand their own systems better and ask the right questions when a service need comes up. We publish new articles regularly, under energy systems, electronics/navigation, lighting, stabilizers, hydraulics, watermakers and climate systems.
If you can't find the topic you're looking for, or you have a specific question about your own boat, write to us through our contact page or browse our full range of services.
A wooden hull, many cabins and equipment added over the years: a gulet's electrical system has its own problems. What we focus on during maintenance and refit.
On a charter yacht, a fault affects not just comfort but the guests' week and the operator's reputation. The electrical checks we carry out before the season and at guest changeovers.
Most generator faults start not inside the engine but in the battery, fuel, seawater and control circuit. Ten likely causes and the order of checks we follow on board.
An ageing battery does not always announce itself. How to time a replacement by measuring, choose the right battery and change it safely.
Why does the RCD keep tripping, and why does the air conditioning struggle in the evening? The most common shore power problems in Bodrum marinas and how we solve them by measuring.
The right boat electrician finds faults by measuring, not guessing, and documents the work. Here are the questions to ask before choosing a service team in Bodrum.
The electrification wave from the automotive world is now reaching yachts too. We explain how hybrid and electric propulsion systems work and what loads they add to a boat.
Digital switching systems, where dozens of switches are replaced by a few touchscreens, are transforming the yacht electrical panel. We explain how it works and what to watch for.
The marina map and season calendar of the Bodrum peninsula shape when and where you should plan yacht electrical maintenance. A practical guide from our field experience.
As important as the hull and engines, yet often rushed: the electrical system. Here is what to check, step by step, before you buy a used yacht.
Battery bank, solar and inverter decisions all rest on one number: your boat's daily amp-hour consumption. This guide shows you how to work it out realistically.
A motor yacht draws its energy from generators and large alternators, while a sailing yacht counts every amp-hour. That difference shapes the whole design, from battery bank to cable size.
You can see your moored yacht's battery voltage, bilge level and shore power status from your phone, provided you choose the right sensors, gateway and alarm thresholds.
A bow thruster draws hundreds of amps within seconds. Get the battery, cable, fuse or contactor wrong and power fades at the most critical moment of a manoeuvre.
The windlass tends to fail exactly when you need it most. We walk through the check order from solenoid to foot switch.
The bilge pump is a yacht's last line of defense. Without the right float switch, wiring and alarm setup, that last line is often empty.
If your split or self-contained marine AC isn't cooling enough, the cause is usually simple: seawater flow, refrigerant level or a dirty filter. Here's the check order we use.
Platforms and cranes that launch tenders and water toys carry heavy loads. We cover the common faults, their causes and a safe maintenance routine.
The gangway is the most visible hydraulic system used every day on a yacht. A practical maintenance and fault-finding guide for the power unit, cylinders and electrical control.
The membrane is a watermaker's most expensive and most sensitive part. Here's how correct flushing, timely chemical cleaning and proper winterizing extend its life.
From the basic principle of reverse osmosis to calculating your daily water needs: how to choose the right watermaker capacity and electrical setup for your yacht.
Hinged plate or vertical blade? We compare the two trim solutions on operating principle, response speed, maintenance and typical faults.
Electric interceptors with automatic pitch and roll control: what Zipwake brings to fast boats and motor yachts, and what matters during installation.
A flywheel spinning in a vacuum sphere, a hydraulic brake and a cooling circuit: how Seakeeper works and what to check for a long service life.
Choosing LEDs for the saloon, cabins and passageways: colour temperature, dimming, voltage drop and VHF interference explained for owners and captains.
Choosing the right navigation lights under COLREG Annex I by boat length, visibility arcs and ranges, and what to watch for converting halogen fixtures to approved LEDs.
Practical field guidance on underwater LED lights, from power, colour and housing material to mounting point, wiring and galvanic corrosion prevention.
Practical field advice on choosing a 4G/5G router and antenna and installing Starlink for uninterrupted internet at marinas and offshore.
A fixed VHF's real range depends more on the antenna, cable and connectors than on the radio itself. DSC only works with an MMSI and a GPS feed.
AIS shows the identity and course of nearby ships during night and fog passages. We explain the difference between Class A and Class B and how to install it correctly.
Holding the helm by hand for hours on a long passage is tiring; the autopilot takes that load off you. A correctly calibrated autopilot is not just more comfortable — it's safer.
In fog, night passages and busy traffic, radar is your most reliable extra eye. We cover choosing the right dome, mounting height and the basic settings that make radar actually useful.
Before buying a new chartplotter or MFD, look at the system rather than just the screen. A marine electrician's view on displays, charts, networking and installation.
NMEA 2000 brings chartplotter, autopilot, AIS and engine data together on one cable and is extremely reliable when its rules are followed. Here is how to install it properly and find faults by measurement.
A few measurements before the first engine start after winter prevent most mid-season failures. This is the commissioning electrical checklist we use in the field.
In winter the real enemy of batteries, cables and electronics is not the cold but self-discharge, humidity and small forgotten loads. Here is how to prepare your yacht's electrical system.
Many boat fires start at a terminal that has been quietly overheating for months. Here is how to read the risks and which measures actually work.
Every device added over the years makes the original panel a little more tangled. Past a certain point, the safest and most economical fix is a planned, full refit rather than another patch.
A fuse protects the cable, not the appliance. The wrong type or rating may not even open during a short circuit; a correct choice depends on interrupt capacity as much as amperage.
An undersized cable causes everything from weak equipment performance to a real fire risk. We walk through choosing the right marine cable and calculating voltage drop with practical examples.
A flat battery in the morning, anodes that vanish too fast or an RCD that keeps tripping can all point to the same fault. Here is how to track down AC and DC leakage step by step, and how grounding should be done.
When an underwater metal part erodes faster than expected, the cause is usually not poor material quality but galvanic corrosion — and the right anodes and isolation control it well.
Shore power seems to offer near-unlimited electricity to a yacht, but the wrong plug, cable or connection sequence can put the boat and the marina grid at risk.
The generator is one of the hardest-working machines on a yacht, and without regular maintenance it tends to fail at the worst possible moment. Here is the full checklist.
Is your engine really filling your house batteries? We compare alternators, external regulators and DC-DC chargers for fast, safe charging on board.
A correctly sized solar and MPPT system dramatically cuts generator or engine dependence on the days spent at anchor.
An undersized or wrongly specified inverter/charger can turn one of a yacht's most expensive electronics investments into a first-season disappointment.
Most lead-acid batteries die early not from age but from the wrong charge profile and neglected maintenance; a few regular habits can easily double battery life.
A LiFePO4 bank nearly doubles the usable capacity on board, but it only works properly when the whole charging system is rethought, not just the batteries.
