Here are the key things to consider for the best possible experience – both technically and practically.
Built-in GPS or external
To show your position correctly, Skippo requires a tablet with built-in GPS – or an external GPS receiver.
Look for “GPS” in the product specifications when choosing your device. For iPads, most models come in two versions: WiFi and Cellular. Only the Cellular version has built-in GPS, even if you don’t use a SIM card.
If you already have a tablet without GPS, there are options. Several users have successfully connected external GPS receivers, such as the Garmin GLO 2.
Some also report that they’ve been able to share location between iPhone and iPad using Apple’s system functions. This may work in some cases, but it’s not always reliable – so we recommend using Skippo on a device with built-in GPS for the best experience.
Storage space
To use Skippo offline – for example, when you’re at sea without internet – you’ll need to download the charts in advance. Make sure your device has enough available storage.
As an example, the full chart for Sweden takes about 320 MB. If you also have saved places, tracks, and routes, the app may use more space over time. We recommend having a good margin, especially if you plan to download charts for several countries or larger regions.
Water resistance
Using a tablet onboard exposes it to an environment far less protected than your living room – splashes, rain, and humidity are part of daily life. So water resistance is important, especially if the tablet is used outside in the cockpit or at the helm.
Manufacturers often list an IP rating for water and dust resistance. But it’s not just about surviving moisture – the screen must also work while wet. It’s frustrating when touch input fails due to a few drops of water.
For the best on-board experience, choose a tablet that can handle damp conditions and remains usable even with a wet screen.
We’ve tested how different screens handle splashes. Results vary – some models deal with moisture much better than others. If you’re using your tablet in open areas, we recommend choosing a model designed for outdoor use or complementing it with waterproof casing and screen protection.
Screen brightness
A bright and readable screen is a must when using a tablet in a boat – especially under strong sunlight. A weak display quickly becomes a problem when trying to read chart details midday.
We recommend choosing a tablet with more than 500 nits of brightness. Below that, it gets hard to see in daylight unless you always stay under cover. A bright screen makes a big difference – no matter the weather.
Battery life
Tablet navigation demands high screen brightness and processing power – which affects battery life. If you’re out for long periods without charging options, battery capacity becomes crucial.
Keep in mind that brighter screens (which are essential in daylight) consume more power. So actual battery life may vary depending on how bright your screen is. A tablet with strong battery life is a safe investment for marine navigation.
Performance
Smooth navigation requires responsive performance. Zooming and panning must be fast and fluid – especially in detailed chart areas. Laggy or frozen apps ruin the experience.
Versatility
A tablet onboard is not just for navigation – it can also be used for entertainment, work, or everyday use at home. That’s why it’s worth choosing a model that fits into life beyond boating to get the most value from your investment.
