* AIS; what's that?......find out by clicking here                    

All these models can use C-Map Max charts, Navionics Plus charts and Onwa's own K-chart versions 2. K charts are free to buyers. All are completely self contained units consisting of a sophisticated multi-function chart plotter with a built in Class B AIS transceiver (some are available as Class B+). One model (K7A) even has an echo sounder/fish finder as well.

Onwa's standard warranty of 18 months parts and service

K-chart2 and K-chart 3 supplied free with every plotter, usually the UK and Ireland chart although these enlarged versions that we supply cover a vast area from Iceland in the North to Spain in the South and almost to The Baltic in the East, Any area of the world can be substituted or as an addition.


7 inch models: £495.00


This 7" widescreen (16x9) format sunlight viewable screen is a new addition to the Onwa range at a price that really makes a smart new plotter with AIS on your boat affordable.

Note. There is a smaller 5" version of this plotter (KP-38A) if space is at a premium that we can order in for you. It is slightly cheaper but do bear in mind that at just 5 inches you do need the screen quite close by unless your eyesight is absolutely top line. 



KP-39A 7" 

KP39A also available with an enhanced Class B+ AIS module £530.00

KP708A mk2 with Class B+ AIS transceiver

An improved mk2 version with faster speed and functionality, this model has the more conventional 4 x 3 screen format, IP66 water ingress rating and has a less reflective screen than the KP39A - in very bright sunlight this will improve the visibility of the display. If you intend to use your plotter at your helm where the sun can shine directly on it you may want to consider this model over the 39A even though they share a similar screen brightness. If the plotter is sheltered from direct sunlight then it isn't really a consideration.

We think spot on reliable GPS is essential for AIS so our KP-708A will be supplied with an external GPS aerial. Intermittent/unreliable GPS signal will prevent the plotter calculating if another vessel is on a collision course.

KP708A 7"

 £639.00 with external GPS aerial and free post to UK mainland.

K-combo 7A   £650.00 + transducer (£99.00)

This 7" 4 x 3 version is amazing. It not only has a Class B AIS transceiver built in but also a 300 watt nominal, 600 watt max', dual frequency echo sounder/fish finder as well; just about everything you need in one unit. A choice of transom mounted or thru-hull transducer available.

99 series models

The 99 series has been around for a few years now and has justly earned a reputation for superb reliability and usability by sailors all over the world. In 2018 Onwa redesigned the 99 as a mk2 version to incorporate faster processors, more memory and other hardware changes; the improvement is quite noticeable. Considerably faster boot up and generally a lot slicker performance. 

KP1299A £999.00

This has a large 12.1" 4 x 3 screen, a built in Class B AIS transponder and a low reflectivity screen for improved visibility in bright sunlight. The KP-1299 has always been our best selling product both in AIS and non-AIS versions for customers with the space available to accommodate this model. This is unsurprising as the clarity and readability of that large screen makes it an easy choice.

You should try to see one of these super plotters; the screen image is impressive. If you have the room for a 12 inch screen you should consider one of these plotters - you won't be disappointed. I have used a 1299A for the last four years on my sail boat and I love it.

Also available as an 8 inch version

KP-8299A £859.00 Same legendary reliability, same features and performance as the 12 inch but just that bit smaller.
