                  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 products sold will now have a 24 month parts and labour warranty.
