About Us

In business since 1963, O'Sullivans Marine is very well established as one of Ireland's best known boat builders, and boat dealers. We have built such great boats as the famous Cork 1720, the National 18 and the versatile Hellraiser HR223, to name but a few. Click here to see the boats we build today.

Particularly, see the Irish Coastal Rowing Federation One Design Rowing Yawl - we are now turning these out on a regular basis - contact us for details, including photos, specifications and prices.

As well as this, we are proud to be the Irish distributors for such famous boat brands as Starfisher, Linder Aluminium Boats, Poseidon Boats and Gemini RIB's and inflatables. Couple these with Tohatsu Outboard Motors, Hidea Outboard Motors or Honda Outboard Motors along with a Brenderup or Snipe Trailer, and we can offer you some of the best “package” deals on the market today.

With over 50 years experience in the marine industry in Ireland, we have evolved considerably over the years. The next phase is happening right now – we are going on line with our chandlery shop.

We have expanded this massively over the past few years and have outgrown our local market, so we are now building an online presence to cope with the demands of international trade.

We pride ourselves in offering excellent value to all our customers – with good quality products and even better prices. Check us out in comparison to the competition, locally, nationally or internationally – we are here to compete and offer a back up service second to none.

O'Sullivans Marine can also help you with all the other aspects involved in owning a boat – including:

  • Servicing and repairs to all GRP (fiberglass) boats.
  • Servicing or repairs to outboard motors (particularly Tohatsu,  Hidea and  Honda).        
  • Servicing or repairs to inboard diesel engines (particularly Sole, Volvo and Yanmar).  
  • Supply and installation of electronics and navigation equipment (particularly from Garmin, Raymarine and Cobra).
  • Service and repairs to boat trailers (particularly Brenderup and Snipe Trailers).
  • PLUS a massively expanded array of chandlery upstairs in the new purpose built showrooms - worth a visit, to say the least!! 


Our brokerage department has a large selection of used and nearly-new boats for sale as well as a selection of outboard motors.
