         ONWA AIS* equipped chart plotters.    


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

All these models can use C-Map Max charts or Onwa's own K-chart systems versions 2 and 3. All are completely self contained units consisting of a sophisticated multi-function chart plotter with a built in Class B AIS transceiver; one model (K7A) even has an echo sounder/fish finder as well.

K-chart2 is supplied free with every plotter, usually the UK and Ireland (covers northern France and Holland too), but any area of the world can be substituted or as an addition.

K-chart3 is a newly designed charting system which is still in development, all plotters featured on this page are K-chart3 ready and will be able to use the new charting system when it is eventually released for Europe,


7 inch models:


This superb 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" 

KP708A mk2

An improved mk2 version with faster speed and functionality, this model has the more conventional 4 x 3 screen format 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.

KP708A 7"

K-combo 7A mk2

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 earnt a reputation for superb reliability and usability by sailors all over the world. Recently 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 mk2

This has a large 12.1" 4 x 3 screen and a built in Class B AIS transponder. Mk2 versions have 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, 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 mk1 for the last three years on my 28' sail boat and I love it; when the season starts in April it will be with a new 1299A mk2.

1299A mk2 is in our January sale at the moment

Also available as an 8 inch version


Same legendary reliability, same features and performance as the 12 inch but just that bit smaller.  

and...….also as a 5.6" version KP-6299A but unless you particularly want the more robust build of the 99 series, I would go for one of the 7" plotters as they are a little cheaper.
