                  Welcome to AVES Marine     

If you are thinking of treating yourself to a new piece of marine electronics this is a place to look. Onwa produce first rate equipment at a price that makes sophisticated marine electronics affordable. Our best selling plotters are the AIS transponder range - you won't find a comparable product for anything approaching the price that these models sell for.

AVES Marine has been selling Onwa equipment since April 2014. We are one of a select few officially recognised re-sellers of Onwa products in Europe. You can find AVES Marine listed on Onwa’s web site as an official seller of their products (http://onwamarine.com/contact-us/) so you can depend upon AVES Marine to sell you a GENUINE Onwa product that is fully supported by the manufacturer. All Onwa products sold by AVES Marine have a parts and labour warranty. For new this is 24 months (new from 12th December 2018) and for used and ex-demonstration items 6 to 12 months depending upon the item.



On 12th December we negotiated with Onwa a new warranty period of 24 months on all new products. From this date all new products will now have a 24 month parts and labour UK warranty.

* free freight exclusions

We would like to offer completely free freight with every sale to anywhere but, sadly, this is simply not possible. Generally, if you live in mainland UK in a populated area freight fees are manageable, however, to Highlands and Islands, Isle of Wight and what freight companies call remote areas, the cost can be quite high. However, if you live in one of these areas we will chip in with a  £10.00 discount on the plotter price in lieu of the free post.
