I get most of the replacements for my Oceanis 40 from the internet. Many of these replacements are from the Italian brand Osculati. If you visit their homepage you can download a huge catalogue of more than 1,000 pages. Most online shops stock the Osculati range or a part of it. Here is a list of online shops that I recommend.
1) From the UK
Piplers of Poole - from where I ordered my present 3D Tender light dinghy.
http://www.g-comm.co.uk which was the only shop in Europe where I could get the wind pod for the ST70 instrument.
Charity and Taylor - in July 2016 my C90W chartplotter start to malfunction. I discovered in Ebay that this firm was selling new C90W chartplotters for the incredible low price of 600 GBP. I bought one and one week after I had it working in Thessaloniki marina to where it was dispatched. Later I discover that these two firms are the same (C&T and G-COMM)
2) From France - since our Oceabis 40 was delivered in Antibes in 2010, I ordered some items at that time from firms kike BigShip, UShip and Accastillage Diffusion. But if I had to buy from France now, I would probably choose
Rue de La Mer - they have a site in both French and English, they stock the Osculati range at good prices and they have a competitive shipping cost for EU countries.
3) From Spain - Accastillage Difusion has a good stock
4) From Greece
http://www.nautilus.gr - I prefer to go to the shops instead of ordering online. The online shop does not stock all the products that they have in the shops that you find over Greece.
http://ioniansafety.com/index.php/en/ - I made the revision of my life-raft and life-jackets in 2013 and in 2016. I bought my new Epirb here also. The owner is Nikos and I truly recommend their service.
4) From Italy
http://www.yachtshop.eu/en/ - This shop stocks all the Osculati range and has the best prices. Their shipping charges are very low except for Greece
.5) From Austria
http://www.aventuramar.es - they stock all the Osculati range. The prices are a little bit higher than the previous firm from Italy but they offer free shipping on orders greater than 250 euros (12 euros if less). Attention: they have webpages/shops in Spanish, English, Italian, Deutsche, French, ... but the prices shown on the Spanish and Italian webpages are lower than in the others. Since our boat is in Greece, I will be ordering some parts very soon.
