The SeaQuest is a 2007 Hallberg-Rassy 48 with construction number 38. We are the second owner since April 2014. Before this we had the Brandaan for 8 years, a Hallberg-Rassy 40 from 2004 also with construction number 38. Brandaan, een Hallberg-Rassy 40 uit 2004, ook met bouwnummer 38.
The SeaQuest is a fantastic boat for longer sailing trips to distant destinations. It is very easy to sail with just the two of us or even alone. The centre cockpit gives a very safe feeling. All sailing manoeuvres can be done from the cockpit and are electrically assisted. Hallberg Rassy calls this “push button sailing”.
The interior layout is beautiful with lots of wood, comfortable with good beds, sofa and chairs, and in many details suitable for use in heavier seas. Think of all the grips in many places, a kitchen where you can stand well 'fixed' and all floors equal without annoying steps.
Due to its weight (the SeaQuest weighs approximately 25 tonnes), it is stable in rough seas. Despite this weight, it is also quite fast!
The SeaQuest has a furling mainsail, a genoa, a genaker and a cutter jib. That cutter jib is not always handy when we have to tack on the Grevelingen or the Oosterschelde with lighter winds. Then we have to furl the genoa before we can tack 😂, but we take that for granted. At sea with heavy seas and stronger winds we are only too happy with it. The furling mainsail is very practical because it is very easy to reef. We use the new furling genaker much more often than the previous one. On a downwind course we soon set the sails in butterfly position with the genoa on the boom. That sails very comfortably.
In short, the SeaQuest was already a fantastic boat with a great combination of safety, comfort, ease of sailing, and a luxurious and rugged appearance. It has become an even better boat thanks to all the modifications we have made over the years (see the list below). As a result, it is now perfectly suited to our needs for living on board and sailing to more remote areas.
