Vital statistics

Hull design and construction

Howard Peachey supplied the hull design - a frameless steel hull with two chines. Steel plate is 8mm on the bottom, 6mm between chines and 5mm on the sides.

Rig and sails

Roller furled headsail about 110%. Hank on staysail. Main with 3 reef points. MPS rigged on retractable bowsprit. Headsail controlled with barberhauls so no jib tracks. [Top]

Above decks

General construction

Deck, doghouse and cockpit are constructed of 3 layers of marine ply, glassed and painted. The deck sits on a stainless steel ring frame. Decks are finished in industrial non-skid. Hull and decks are cream, cockpit interior white.

Industrial strength rails fore and aft finish at the bow in a pulpit with a seat, and in a "jungle gym" at the stern, with a dinghy on davits projecting behind. All of this is built from stainless steel. Lifelines are stainless wire.

Steering positions

Nahani has both tiller and wheel steering. The tiller has a trim-tab attached which makes it as light to steer as a dinghy. In less clement weather or on long night passages, the boat can be steered from a wheel mounted to the right of the companionway, under the doghouse.

Navigation aids

The original GPS is mounted on the port side of the companionway. On the starboard side, above the wheel we have mounted a small huon pine dashboard, which has the mountings for removable Tacktick depth and wind displays, and the controls for the Coursemaster autopilot and Seiwa Explorer3 Chartplotter. The chartplotter screen is mounted on a support post which carries electric cabling from below decks to the doghouse roof. All of these navigation aids except the original GPS can removed and locked below for security when the boat is in the berth. The Seiwa Radar, mounted on the jungle gym, is integrated with the chartplotter, as is the AIS.

All the engine controls and gauges are mounted on the front of the lazarette. When the boat is in the berth, these can be covered by a panel which is locked down when the lazarette is locked.

Power supplies

Two solar panels, mounted on the doghouse roof, and a wind generator mounted on the jungle gym.

Lazarette and anchor locker

A benefit of the squared-off transom is that Nahani has a huge lazarette at the stern, which provides storage for an Admiralty anchor plus poly rode, lots of spare lines, outboard fuel containers, oils, paints, varnishes and other chemicals, the dinghy outboard, an inflatable kayak, etc. The equally capacious anchor locker at the bow holds another spare anchor, 100 metres of chain for the main Rocna anchor, the staysail, MPS and storm sails, plus more spare lines.

Below decks

From the cockpit, you enter the main saloon via a steep five step companionway. As you stand at the foot of the companionway, the galley is on the port side and the big nav station on the starboard side (designed to be used standing). Beyond that is the saloon area, containing four sea berths (two each side) and a large table made from an single piece of swamp kauri which was once the top of a sea chest.

Further for'ard a door leads to the main cabin. It has a big double bunk on the port side, masses of storage under the bunk, along the starboard side and across the boat behind the bulkhead that separates the interior from the anchor locker.

Turn to face aft, and you see two more doors on either side of the companionway, leading back aft. On the starboard side the door opens into the head, and beyond that a utility and storage area known as "the shed". On the port side, the door opens into a guest cabin, with another large double berth.

Notable features of the interior are the headroom (about 6'6"), the warmth created by a variety of recycled timber - oregon for structural items, cedar wall panelling and tasmanian oak floors - and navy upholstery, all lightened by cream walls and ceiling.

From below deck you can lock down the anchor/sail locker and the lazarette. The companionway is closed by storm boards which are made from marine ply with stainless steel liners, and a heavy teak sliding hatchcover.

The engine (a 110hp Yanmar turbo diesel with intercooler), lives behind the companionway steps (removable for access), with inspection ports from both the shed and the guest cabin. [Top]


We acquired a beautiful, well-laid out, strongly-constructed boat when we bought Nahani. But as any boat owner will tell you, there is always something to spend more money on: they say that BOAT stands for "Bring Out Another Thousand". Most of our money has been spent on technology, which the captain loves, and which also makes it easier for a couple of elderly yachties to sail the boat two up. Roughly in chronological order, we have:

The only major modification to the sailing fundamentals was having the boom shortened and the mainsail accordingly reduced in size. The main benefit was that the boom no longer reaches into the cockpit, making it safe to stand up to adjust the mainsheet and traveller even when the boat is at risk of a jibe. It also makes the boat more manageable under full sail.

Changes recommended by the surveyor when we bought Nahani were the replacement of the original lifelines and jacklines, both of which were made of plastic covered wire. The lifelines are now stainless wire. In the case of the jacklines we initially put in spectra lines, but subsequently replaced them with Wichard jacklines - flat tapes which are safer if you walk on them, and which also have a luminous strip for night visibility.
