    POSTHASTE IV

    POSTHASTE IV

    2006

    POSTHASTE IV is a 34′ lobsterboat-inspired day cruiser.

    Her owner, an experienced Maine yachtsman, came to us with the basic concept, which we then took from drawing board through construction to final launching and shakedown.

    The cockpit provides a beautiful environment to explore the coast or simply enjoy an evening at anchor. A bronze wheel and custom helmsman’s seat provide a traditional look, and full electronics were included: radar, GPS, depth sounder, and VHF. Varnished mahogany and oak complement the teak sole.

    Satin varnish and a custom soft off-white are used extensively below decks. Large beveled glass windows – they’re too large to really be called “ports” – add to the light and airy interior.

    The curved cabin sides were laminated from mahogany with inner laminations of Meranti plywood for stiffness and stability. They were then varnished inside and out. Curved windows were custom made for POSTHASTE with cut bevelled edges.

    POSTHASTE IV was built in traditional lobster-boat fashion, with steam-bent white oak frames bent inside ribbands. The planking and backbone were both made from sustainably-harvested Central American hardwoods: the planking is Wana and the backbone is Angelique. As planking proceeds, the ribbands are removed. Planking started at the sheer and moved down the hull. Shortly after this photo was taken, we began planking from the keel up, leaving a “shutter plank” as the final plank to put on.

    WOMBAT

    25‘ V-bottom launch (1992, 2026)

    WOMBAT is a cold-molded version of William Hand’s Piute III design, built by H&H Boat Works in 1992. When she arrived at our shop, she had already been converted to electric propulsion, but her owner was not getting the reliability or performance he expected.  The existing system overheated frequently, and the temporary fix was to reduce the motor’s maximum output from 15 kW to 10 kW.  Even before that reduction, the boat had fallen short of his speed and range goals.

    With those goals in mind, we designed a new system to deliver the power, range, and confidence he was looking for.  Estimating the right motor size required some careful judgment: WOMBAT’s hull design dates back to the early era of planing boats, and the old motor never produced enough power for meaningful testing at higher speeds.  Our experience with Harry Bryan’s Handy Billy – a similar boat we have built several times – provided the best guide.  Though those boats can typically reach about 15 knots with modest power, WOMBAT is longer and more than twice as heavy.  After weighing the variables, we determined that 40 kW was the right target.

    For the repower, we selected ePropulsion’s I40 inboard: a water-cooled, 96V, 40 kW motor, paired with two ePropulsion G102-230 batteries providing 23 kWh each.  Nautilus Marine supplied a new stainless steel shaft and bronze propeller.  In anticipation of higher speeds, WOMBAT’s owner also asked us to add full-length spray rails and wedges.

    Sea trials in late May confirmed the system was the right fit.  After a small propeller pitch adjustment, WOMBAT performed flawlessly, reaching nearly 17 knots at full throttle.  She trimmed well on plane with help from the wedges, and stayed dry in all but the steepest chop.

    Now back in southern Maine, WOMBAT is ready for the final carpentry phase, where her owner will build cockpit benches around the batteries and box in the prop shaft through the cabin space. We’re looking forward to seeing those finishing touches come together – and even more to seeing WOMBAT back on the water, delivering the quiet cruising, simple operation, and satisfying speed her owner envisioned.

    BRENDA KAY

    29′ Beals Island lobster boat (2010)

    BRENDA KAY is a cold-molded reproduction of a 1950’s Beals Island lobster boat. The original boat, re-named DIANA after a 2001 restoration here at Hylan & Brown, was designed and built by Alvin Beal in 1952. She plied the waters of Downeast Maine for nearly a half a century until she came to us for a complete restoration and conversion to yacht standards. Lines were taken and plans worked up in the hope that someone might be drawn to the classic lines and much-proven seaworthiness of the type.

    In 2009 a customer from Virginia, having admired DIANA, commissioned a reproduction. To the eye, BRENDA KAY is a perfectly accurate copy of the original, belying the modernization of her construction and equipment. Her hull – with 8” of additional beam for space and stability – is cold molded, and she is powered by a 110hp Yanmar diesel engine turning an Evolution Marine Shaft System.

    BRENDA KAY won First Place for Professionally Built Powerboat at the 2010 WoodenBoat Show in Mystic, CT.

    BRENDA KAY is perfectly suited to short cruises with her simple yet comfortable accommodations, and her cockpit provides ample room for guests on day trips. At speeds up to 16 knts she cruises with comfort, safety and traditional style.

    DELIVERANCE

    43′ Workboat-inspired cruiser (2011)

    DELIVERANCE’s story began when a long time customer saw the design for MANATEE, a tiny coastal cargo vessel, originally published in The Rudder magazine in 1921. We extensively reworked her lines – beam and length were increased, draft and displacement reduced, her forward deck raised for better accommodations, and her forefoot cut away for better handling is a seaway. But her handsome workboat origins and classic detailing remain dominant.

    DELIVERANCE is a good example of what Hylan & Brown Boatbuilders has become known for: re-interpreting classic designs, and building them using the best combination of traditional and modern construction methods.

    VEGA

    31′ Cranberry Island Launch (1936, 2023)

    VEGA was built on Great Cranberry Island In 1936. She spent the next 84 years enjoyed by one family and stored carefully on island. She came to us in remarkably original condition by way of Maynard Bray’s “Save a Classic” Column in WoodenBoat Magazine. Her new owner was interested in perpetuating the original fabric and spirit of the classic launch, while also converting her from gasoline to electric power.

    His intended use was well suited to electric power: regular joy rides, picnic excursions and cocktail cruises off his dock (with shore power) in Sorrento, with an occasional cruise to Stonington, Brooklin, or even western Penobscot Bay. The boat was a great candidate for electric, too: fine bow, long waterline, narrow beam and a not-quite submerged transom.

    The conversion was a success. With one season under her belt, we learned a lot about her abilities: She can easily go from Brooklin to Sorrento on a single charge; She can make regular short cruises and re-charge on solar alone, and a lot more.
