The condition or level of safety equipment on board is not to be negotiated on following survey. It is likely to be listed by most surveyors but is not structural or an integral working part of the vessel and is not to be used to further negotiate the price down after survey. We strongly suggest that for your own personal safety that when purchasing a yacht you provide new safety equipment rather than relying on second hand gear.

Should you become the new owner of this yacht then the responsibility to re-register or update official bodies for items such as EPIRB, VHF, MMSI or AIS becomes yours.

Owner Comments

Our syndicate is the 4th owner. We understand the previous three owners used her very lightly, cruising the East coast of Ireland and the West coast of Scotland. Since buying in the summer of 2010 we sailed her to Suffolk Yacht Harbour for a major refit as detailed above; and since then we have continued to renew, replace and upgrade many items both above and below decks to maintain her in a fully operational condition. She has been lifted out every winter with all running rigging and sails washed, dried and stored below. Dinghy removed, washed dried and stored below.

We sailed from the UK to Portugal in 2012 and have cruised extensively in Spain, the Balearics, Sardinia, Corsica, Italy, Sicily and her outlying Islands before over wintering in Malta in 2015. In 2016 we sailed to Greece where we have cruised around the Ionian and Aegean Seas for the past 3 years. As a live-aboard cruising yacht she is superb, with great sea-keeping qualities, wide decks, a deep safe cockpit, easy handled sailing set up with control lines to cockpit, good sailing performance and with a strong engine (for when needed!). Extensive inventory of spares and tools for most eventualities.

Manufacturers Comments:
The Seastream 43 was designed by Ian Anderson MRINA to meet the need for as stable cruising yacht, that is capable of world cruising, without any modification. She has a stiff, sea-kindly hull, based on a traditional underwater configuration, which gives good directional stability and yet allows a responsive ‘feel’ when under sail.

The light, airy deck saloon offers the ultimate in comfort, both at sea and in harbour. With an interior helm position, the owner is encouraged to extend his sailing season and explore further afield, as the fatigue created by exposure is eliminated.

New features abound aboard the Seastream 43. She has many comforts found in the modern home and yet she has a remarkable sea-going ability. The flush foredeck gives excellent all round visibility for the helmsman and crew, either seated or standing, from both the cockpit and the interior steering positions. It provides a safe working area while at sea and becomes a huge sunbathing area in harbour or in calm conditions. Wide, safe side decks enable the most cautious crew to move forward without obstruction. The teak interior is hand finished.

There are berths for at least seven people in three separate cabins and the deck saloon. The galley offers all the facilities found in an up to date kitchen with plentiful stowage for a massive amount of food.

The Mercedes engine was selected as it has more than adequate power for the roughest conditions and, in the unlikely event that spares are needed, they are readily available anywhere in the world. Great care has been taken to ensure that the noise level is kept to an absolute minimum; a special exhaust muffler and lavish acoustic sound deadening materials have been used.
