How To Use A Screw Extractor

On the hunt - Hunter's e36

The  Hunter range has long included a 36’ yacht,  but the style has been evolving, and the current models are significantly different to look at than boats that are just a few years old. Broadly speaking the style changes are in keeping with those already introduced in their larger yachts, such as the 45’. Externally the most noticeable change is the coachroof windows, which now appear to number four on both sides of the boat, collectively conforming to a double tapered ‘sunglass-style’ envelope. They are heavily tinted and create an eye catching curve rather than appear just as a row of windows, and in fact one of them on the port side is blind, and the aft one on either side actually has slots cut through it, effectively hiding inward opening rectangular ports in the coachroof while allowing air to enter. I liked the overall appearance. There are a lot of other interesting, well thought out details built into these boats, and quite a range of options and additional ‘packages’ available. There won’t be space here to detail those, but they allow the Hunter 36 to appeal to a wide range of  owners, whether individuals, charter operators, or as members of a syndicate.  The Australian importers (US Yachts Pty Ltd)  manage such syndicates, including the e36 which formed the basis for this review. Hunter yachts are built in Florida, mostly on dedicated production lines. They are imported to Australia within RoRo ships (130 boats to date, ranging from 17’ trailer sailers to 50’) with keels already attached, and the rigs virtually ready to step. They are usually sailed to their owner’s port, although trucking is more economic to places like Darwin. Claimed lead time on delivery is about 3 months from placing the order. The e36  hull is actually only 34’11” and 34’5” at the waterline (you’ll learn why they call it a 36 later in this article). The hull is essentially solid GRP beneath the waterline and  end-grain balsa laminate above, with osmosis resistant  vinylester resins under the gelcoat, and alternating layers of chopped and woven reinforcements, including  judicious use of  kevlar and other special reinforcements in appropriate areas, i.e. forward edge of the keel to the bow.
