The best boat upgrade ideas: Everything you need to know

1.JL Audio Marine Source Unit

Best boat upgrade for music enthusiasts


Your boat may not have been brand new when you bought it, but you can still upgrade that factory-fitted radio unit to brand spanking new. These days, it’s all about playing your favourite tunes, and the JL Audio Marine Source Unit allows you to plug in your favourite playlists, thanks to both USB and AUX connectivity.  With an ultra-modern, weather-proof coloured display, the JL Audio Marine Source Unit is as snazzy as it is practical, making it the perfect boat upgrade.

2.Bimini Tops

Best boat upgrade for shade enthusiasts

The flybridge– an excellent place to enjoy champagne and cocktails. Unlike the seating area at the stern, the flybridge is often exposed, making it too hot to really enjoy that refreshing drink – and if it starts raining, then your party will just get wet.  A Bimini Top is a simple way to get that shade and rain protection. Bimini tops are available in a range of widths and are designed to clamp onto your boat railings. They’re suitable for motorboats, cruisers, fishing boats and RIBs.

3. Snap-In Carpets

Best boat upgrade for an interior revamp

Best boat upgrade ideas: snap-in carpet

Whether it’s a spillage from a meal with friends and family or marks from traipsing in and out with wet, sandy feet, the carpet is one of the first parts of the interior to show signs of wear and tear. Thanks to the innovative invention of snap-in carpets, it’s now super-easy for you to replace your carpet. Attached to the cabin floor by little rivets and poppers, upgrading your boat carpet is as easy as removing the old carpet, and popping in the new one.

4. LED Subwoofers

Best boat upgrade for party people

Subwoofers themselves are already a great boat upgrade, but when you add LED lighting into the mix, they really can take your boat to the next level. We stock a great range of LED subwoofers and have a variety of LED colours for you to choose from. Available in a range of sizes, the subwoofer should be able to fit into one of your original speaker settings, making it an easy enough installation job for someone who's familiar with speaker wiring.

5.Wakeboard Tower

Best boat upgrade for thrill-seekers

Possibly one of the easiest boat upgrades to carry out, purchasing a wakeboard tower will instantly take your boat from a cruiser to the ultimate toy. A must for any speedboat owner, a wakeboard tower will have you and your friends messing around at sea and down the river in no time. Not just for wakeboarding, a wakeboard tower is ideal for towing paddleboards and dinghies, meaning you can get straight to playtime on a sunny day.
