SeaStream 34 Yachts



Swanky Lady

This might be the first ever Seastream. It was a demonstrator boat for the media back in 1977 and then bought at a slight discount by the first owner. She was lifted out to fit a bow thruster and remained ashore for 30 years to rot. Since then Andy bought her for £1 with aim of restoring her to her former glory! The hull will have been built to Lloyds standards and most likely done with extra care, being the first. The photos below show her state as of June 2023 including a single photo shows her under sail in Yachting Monthly,1978.

MODEL: 34 Ketch
OWNER: Andy Bore



Cloud Nine’ is a Seastream 34, ketch rig, built in early 1979. The current owner watched her being built, named her, registered her, and took delivery as new in May 1979. Cloud Nine is thereby a much-treasured yacht meticulously maintained by her current owner for 44 years.

Celerity is owned by a German couple traveling on her since September 2022. They bought her in May 2022 in Greece from an Austrian/German couple which used to spend the summers on her in the Mediterranean Sea. Prior to that she was in Lossiemouth, Scotland.

They started sailing her end of September 2022 with the aim of circumnavigating. As of September 2023 they’re in the Caribbean.

Built by Wilson Manning on the Hamble in 1986, Django is believed to be the last Seastream 34 to be built, furthermore, she is one of the very small number of sloop rig variants. Below decks, Django is powered by a Perkins 4108 and has the saloon steering position on the stbd side, both of which are variable across the class. Django is now owned by a Dr F Schmidt, bought in 2018. He intends to start restoring/refurbishing the boat to her original glory over the coming winters. It is believed there have been 4 previous owners.

VETUS M17 42hp (New 2014)
LOCATION: Portsmouth, UK
Owner: Richard Waldron

Previously known as Redemption, the current owners have had her since 2016 and renamed her to Bella May. The current owners have done lots to her including complete upholstery, enclosed cockpit covers / spray hood. She has been laid up every winter in my sailing club in Southsea / Portsmouth ECA.



MODEL: 34 Ketch
BUILT: Hamble
ENGINE: Mercedes OM63 (Original)
LOCATION:  Germany

Built in 1979 in Hamble, Southampton. Hull number 9. It was been sold for £27,000 to the first owner, a former captain. It’s first name was Ansidade. It has been sold in 1998/99 to the second owner, new name Beluga. He refit inside and the motor has been refurbished, the original Mercedes OM636. He wanted to make longer journeys with the yacht but unfortunately his wife gets seriously sick and he wanted to spend more time with her, so he sold the yacht in 2001.

I renamed it into Temoe, this means sunrise in Polynesia (I think). Since 2002 we sail in Netherlands water, our child has been born in 2002, so the trips have to be a little shorter than my wishes are. Nevertheless, we still have a lot of fun on our boat and as ever I’ve been asked about this “goodlooking yacht”. We are proud to own a Seastream. We always feel safe in the rough coastal water, so mostly I could wear shorts and T-Shirts while the sailors on the modern yachts wear rescue equipment.

SeaStream 43 Yachts



MODEL: 43 MK1 Ketch

Perhaps the first ever Seastream 43. I have had Boatsong for about 6 years now (Mark I, 1980 built on the Itchen, Solent Shipyard). She has always been kept in the Caribbean, currently in Carriacou. Since I have owned her, I have replaced almost everything mechanical and electrical on her (and standing and running rigging, water tanks etc)… just a few things to go! Not worried about the aesthetics so much yet, but we are able to enjoy a good solid, boat that works.

MODEL: 43 MKII Ketch
ENGINE: Perkins 80hp diesel
YEAR: 1987 (Southern Boatbuilders in Southampton)
LOCATION: Portland, Dorset
Owner:  Ruth & Tim Narramore

REMI is our first yacht, and we’ve spent a lot of time getting to know the complex systems in the year since we bought her. We’ve greatly improved reliability of the electronics by fully rewiring the instrument panel and the 9 different data networks on board. We’ve added a large inverter and 1200Ah battery bank, electric cooking (no gas on board now) and recently fitted a stainless bimini gantry and hinged davits – this will provide shade and solar power top-up later. Next phase is an upgrade to 48V electrics system, doubling the battery capacity again and replacing the Perkins diesel with a pair of electric motors. A combination of generator, hydro-regen and solar panels will provide power inputs. Currently the project is paused because we got the green light to go sailing, so that work will restart that in late summer 2021.

HIN: S43993 / MMSI: 512008918 / CS: ZMW8124
BUILT: Falmouth
ENGINE: Perkins M90
YEAR: 1994

BUILT: Seastream, Falmouth
Perkins M90 4.236 (80hp diesel)
LOCATION: n/a (currently cruising)

One of the last of the MkIII’s to be built and completed in Falmouth under Ian Andersons’s supervision. In fact Tournesol was the last hull to be molded but was completed in 1995 prior to Shadowfax. The man who commissioned Shadowfax has a lot of input to the build with the crash zone on the bow as he was fixated with hitting a growler container on his Atlantic crossings, so the bow was reinforced with extra fiberglass and the forward bunk made as water tight as possible with the added security of the water tight door without going to the extremes of a metal submarine door.

The high quality of the woodwork was because the team were not in a rush to launch and were basically cabinet makers. At one point they told the owner he had a 43 foot peace of furniture. There are lots of additions on the boat like the internal handrail in the saloon deck head the solid teak laid decking internally.

Shadowfax has been upgraded to over the last 5 years and the modifications include conversion of bunk room into a workshop, Webasto water and air heating, series drogue setup, window storm boards, hydrovane self steering gear, 420w solar panels, AIS, Spade Anchor, 100m shore lines and more. She still contains the original generator, engine and watermaker which continue to function.



BUILT: Seastream, Falmouth
Perkins M90 4.236 (80hp diesel)

Possibly the last of the MkIII’s to be built before Cantara (below). Since upgraded and appears to be well maintained with a few nice additions such as a fixed lower sprayhood and a furling cruising chute. Awaiting more details but a 2018 survey is available on request to other members.


SeaStream 465 Yachts



MODEL: 465 (lengthened 43)
BUILT: Seastream International
YEAR: 1998
LOCATION: Kip Marina, Renfrewshire, United Kingdom (last known)
OWNER: unknown



SeaStream 650 Yachts



MODEL: 650 (actually 70′ loa)
Displacement: 33T approx

Manatea was the first and only 650 built. Sadly as it was the only  650 built as Chris Matthews, Seastream’s new owner, died in a helicopter crash just before the completion of Manatea and the 2nd hull was then stopped by the executors of the estate. Fortunately Manatea was completed by Oyster Yachts in 2005 but Oyster then destroyed her mould so she became the only boat built of this model.

The boat was intended to be a competitor production yacht to Oyster & Swan. She was designed by Dubois Naval Architects and built at Southampton Yacht Services in England in 2004.

Manatea was initially called “Celera” and was first acquired by an Australian who sailed her out of Brisbane and used her to cruise the Queensland coast, New Caledonia and Vanuatu.

A new owner, Bob Hayward, then used her to cruise the Fijian Islands (on her passage from NZ to California), Southern California, and Baja Mexico. She was raced in the 2013 Transpac and had the honor of being the first monohull to finish in Honolulu.

“Manatea” is derived from the Polynesian words “mana” (your personal being or personal strength) and “tea” (clear). Together they mean (well to us anyway) “clear being” which is what we feel when we’re under sail on the ocean.  It’s also why our logo is 2 leaping dolphins.

Unfortunately Bob lost Manatea to a fire in the hydraulic power pack under the floorboards when cruising the Inside Passage in British Columbia in July 2015. She burnt to the waterline and sank. Fortunately no injuries. They had done the Van Isle 360 Race around Vancouver Island and she had been performing fabulously until that time.  We had spent a lot of effort to get her into top condition and were intending to sail her to New Zealand.
