Sunreed 70 Power Cat ONDIN Launching at Gdansk

Sunreef Yachts said today it has launched the second in the expedition series of 70 Power Catamarans; this one named ONDIN and sold to a Chilean couple who plan to explore Patagonia. The long-range yacht will depart the shipyard in Gdansk soon and make a transatlantic passage, followed by a Panama Canal transit and final leg south to Chile.

The extreme range of the Expedition version of the 70 Sunreef Power Cat is a function both of the extreme efficiency of its wave-piercing hull design, and its propulsion system, which features twin Volvo Penta 265 HP diesels, fed from tanks holding approximately 4,227 gallons (16,000 L).  Range is 7,000 NM on full fuel tanks at 10 knots. Not only is that more than sufficient for any transoceanic crossing, it’s sufficient to enable the captain to wait for the best price or quality to refuel.

ONDIN features some changes from the first 70, JAMBO, which is currently in the South Pacific. You can read more about JAMBO and the whole 70 Power series here. Most significant is the modification of the giant flybridge to incorporate the helm station in a covered enclosure with direct access to the interior. The aft section becomes an open area for entertaining or outdoor dining with the addition of tables and seating. The standard interior helm station on the mezzanine level has been removed and the area converted to an entertainment zone with seating and LCD TV.

Grand Banks Launches New 55 Aleutian RP Yacht

Current 59 Aleutian RP from Grand Banks - New 55 Aleutian RP Has Similar Profile

Current 59 Aleutian RP from Grand Banks - New 55 Aleutian RP Has Similar Profile

An e-mail from Grand Banks last week to current and prospective customers invited them to a private micro website which reveals the existence and details of a new junior member of the Aleutian raised pilothouse series of yachts the company is building.  The new 55 Aleutian RP is intended to offer “outstanding long-range capability,” according to an overview of the new yacht on the website.

The new 55 Aleutian RP is not simply a smaller 59, according to Grand Banks, although in renderings it retains all the classic lines of the Aleutian models.  The company says it did a complete re-evaluation of everything from hull design to layouts and made a number of changes as a result, including a new three-cabin layout, and a redesigned engine room with significantly more space.  The website shows video of  a hull model of the new 55 being tank-tested under various simulated sea-states and speeds at the University of Michigan in Ann Arbor.  Grand Banks says it also built full-size, walk-through mockups to validate the new layouts and storage areas.

The website was noticeably vague on propulsion details, although one section notes the yacht will be outfted with -blade props from ZF, measuing 34 inches in diameter by 31 inches in pitch, and tuned to S-class tolerances.  The boat will also be equipped with Delta T™ Air Demisters and a full Fireboy automatic fire suppression system with automatic engine, generator and ventilation shutdown.

When asked for artist’s renderings for this article, a Grand Banks representative said the company was not ready for a full-blown media launch but would start advertising in October.  It seemed clear from the website information that the first hull was already under construction but that could not be confirmed by press time.  As we find out more about this boat, you will see and read about it here on OceanLines.  In the meantime, here are the basic specifications of the new Grand Banks 55 Aleutian RP as provided in the preview website.
