Lake Rotoiti – Okawa Bay Holiday Camp 

Today’s photo showcases a classic kiwi boating scene, this time on Lake Rotoiti. Given the appearance of several jet boats and the cars in the background, I would guess the date as the late 1960’s.
Anyone able to pin the date down and also ID the woodys seen middle right side of the photo.
During the CV-19 lock-down I spotted the photo below of KZ-7, New Zealand’s first tilt at uplifting the Americas Cup in Perth. The boat on the trailer was actually a life-size model that toured the country as a part of a fund raising roadshow. I was involved in the marketing of the challenge back then, hell 30+ years ago. The photo prompted me to find a model I had of KZ-7. No kneels on show as it was all very hush hush back then.
As part of the campaign there was an extensive range of branded merchandise the public could buy to support the team, everything from t-shirts to replica solid silver cups. Now you would have thought apparel would have been the #1 seller but no woodys, biggest selling item was branded tea-spoons. Seems there was (might still be?) this worldwide group of people that collected tea-spoons, didn’t matter what was on it – just had to have the newest one to add to their collection.

Woody Jet Boat

Including the words ‘jet boat’ in the story headline could be slightly off putting to some, but today’s boat just ticks so many boxes it was an automatic Monday story.

The hull design is inspired by a picture on the workshop manual for the Hamilton Jet Rainbow unit, and is typical of the period of the unit (1956).
The jet unit has been completely rebuilt, including all new gaskets and bearings, and a freshly rebuilt impellor.
The engine is a 1956 Ford 100E Prefect (which the Rainbow unit was designed for). It has been professionally re-conditioned, was re-sleeved, and has new pistons, valves, bearings, oil pump, gaskets etc. All major parts that were re-used (block, head and crank) were crack tested before being re-machined. I.e. No expensive was spared.
The engine is cooled by a modern savage heat exchanger and runs a modern sand filter.
The 12’ hull has an aluminum planning surface (to aid longevity) but is otherwise constructed mainly of recycled kahikatea, rimu, Southland beech and kauri. The sides are Fijian kauri marine ply.
The Art Deco style trailer is a work of art, it was custom built by Ted Sagar of Rivercraft Marine exclusively for this boat.

She was launched in 2007. Her owner has another project planned, shed space is required, so now is the chance for someone else to own this little beauty.

And I want the truck – always had a soft spot for the Willys Wagons.
