Mark Hansen in North Queensland sent in some pics of his new 9.4m (30’-9”) alu outrigger build. Looks pretty amazing!

Hi Guys,

The boat I’ve designed is a bit like one of John Maple’s Constant Camber Tris, but I’ve built it out of marine grade 4mm plate aluminium. After seeing the hull shape, a lot of the locals can’t believe I’ve managed to get an 80ml camber into the side plates, thus bending this very stiff metal two ways.

The interesting thing is, the main hull is virtually finished and still only weighs 378kgs. The reason I went to such a heavy plate is because we live in Far North Queensland, on the Great Barrier Reef, and I have found that plate aluminium endures much more punishment than fibreglass or plywood boats.

Mast is 8.6m high an about 1m tilted back with a 20sm leg of mutton main sail [mylar genoa] 8.0m by 7.75m by 5m all very experimental, and a conventional 10sm jib. The ama and main hull centres will end up about 4m apart. I can’t think of anything more right now so I’ll let you go.

I wonder what Woolridge would charge to whip out a dory hulled 24 footer with 1” of closed cell foam for insulation sprayed on the inside surfaces.  I could line the interior with a nice veneer myself….

Mark Hansen has sent along some launch pics of his new outrigger. Congratulations, Mark! His blog is MOTUMARK*S WORLD.

Hi Guys, I finally got the boat in the water, it slips along really well. I was more than happy with its performance, I’ve got to sort out a some sort of safety ama cause she wants to lift the outrigger over about 12/14 knots of wind.

That is one nice looking tacking outrigger!

Looks very similar to a Wharram but setup as a tacking outrigger instead.
I believe it will a very nice handling boat. A much softer ride than a stock Wharram, because of the dominant main hull.

Johannes.
