If you still have no idea for a maritime Christmas present - perhaps the latest idea by the German Society for the Rescue of Shipwrecked People will solve the problem: a Bluetooth loudspeaker in the look of the popular collecting boat.
The so-called "sound ship" is a custom-made product from the Bremen loudspeaker manufacturer Ceratec and is initially limited to 1000 copies. The output power of the amplifier with three loudspeakers built into the fuselage is a maximum of 50 watts. The device came via Bluetooth from a distance of up to ten meters from a computer, smartphone, tablet or home theater system. It can also be used as a hands-free device for smartphones. The power is supplied via a power supply unit.

The deck of the sound ship is a loudspeaker grille
The little boat with music is available directly in the sea rescue service's web shop. It costs 295 euros.
