This sinister sight greeted the members of the Cambridge Model Boat Club at their Sunday morning sail in Cawcutts (freshwater) lake on the outskirts of Cambridge.

It isn't just a submarine with a fin, but a specially built model with the ability to dive under radio control. It is ballasted to float with just the fin above water. Make a change from Ducks and Swans etc

Looks impressive barrie

plus looks like you have a decent size lake to play on,
would like to see more photos of the shark out of the water ,Well done to whoever had the idea to build it

barriew · « **Reply #2 on:** July 18, 2012, 07:03:34 am »

I'll see if I can get some photos of it out of the water. I know the fin and "body" of the shark are the hull of a Victoria yacht, but the remainder are not anything like a submarine being basically a sealed box with a weight suspended from it.

However, it may be a while before it appears again - the builder likes challenges, but then moves on so I'm not sure when he will bring it to the lake again.

I too am very interested in the details of this "model." I want to build one, but with an orca fin. They are much more common in Washington state waters.

Now an RC water snake would be interesting.

You have things lurikng in the park too -

Due to vandalism of electrical services, barbeques in the park are out of order.
I would have thought vandalising a Barbie in Oz was a hanging matter

Many years back at Plumpton Show, a guy turned up with an r/c Nessie, complete with illuminated red eyes and a tartan bonnet. I only ever saw it that once, but it made a refreshing change from r/c ducks, swans and geese.

I remember the Nessie, quite a scene-stealer. It would engage a child or someone in the crowd in conversation,with a speaker then wet the victim with the built-in squirter. loadsafun

U-33 · « **Reply #12 on:** July 24, 2012, 10:13:13 am »

That sounds about right, I'd forgotten the water spray...it was brilliant, the kids loved it. I wonder if anyone has any pics of it?

Arrow5 · « **Reply #13 on:** July 24, 2012, 10:21:31 am »

Yes I have but cant lay my hands on it at the moment, I`ll have a search.

Sorry - bad attack of hay fever, plus need to go to Cambridge twice this week (about 50 mile round trip) for hospital so I didn't go sailing on Sunday therefore no pics of the construction. Will try again next Sunday.

Nick sorry to hear the park was hit damaging a BBQ is just wrong was the club house ok hope to visit again soon as the back injury is ok have a large rod in the back at present ,who in the right mind would damage a BBQ tassie48

nick_75au · « **Reply #16 on:** July 24, 2012, 11:56:23 am »

Hi Tassie48,
They didn't get the BBQ or clubhouse, It looks like they wrapped a rope around the cables coming out of the bottom of the main electrical panel for the whole park then used a car to rip them out. Hope you get better soon, your always welcome to visit, Did you see the Ticonderoga hull hit the water a couple of weeks ago?.

Sydney is still a few weeks from initial sea trials, Never got back to you about the CCP

Cheers
Nick

Neat!! A big one of those would clear a Spanish Beach pretty quickly I think! Come to think of it, almost any beach!

barriew · « **Reply #19 on:** July 29, 2012, 12:24:30 pm »

A couple of photos of it out of the water.

In front you will see his skeleton powered rowboat. Apologies for the picture quality - taken with my new phone which I have not yet got sorted

As you will gather, he doesn't build the obvious!

Barrie

U-33 · « **Reply #20 on:** July 29, 2012, 01:19:54 pm »

Now that's something I could take a fancy too, Barrie...do you have any construction details of it? Or could you get some, please?

Rich

barriew · « **Reply #21 on:** July 29, 2012, 02:02:27 pm »

Sorry Rich, but its made from odds and ends he had, plus bits he made. He was a Tool Maker by trade and has a full workshop at home. As I said, he is motivated by the challenge, then moves onto something new. The only "standard" item is the Victoria yacht hull which provided the body and fin. He did say the biggest problem was making it watertight. Also he is using a 2.4Ghz set, and so if he goes too deep too far off shore, he loses control

Obviously a 27 or 40 Mhz set would be better.

Hi,
What is the drive for the rowboat?
Regards

barriew · « **Reply #23 on:** July 29, 2012, 02:12:42 pm »

I think it uses a device which a contributor to MB made available 18 months or so ago. I believe it uses two servos, but could be wrong.

That's great Barrie, thanks for that...I've had a quick look in my cupboard and found the best part of a 575 hull, but it's bit on the small side...ideal as a test bed though. I have a small wtc, plenty of micro servos...hmm. Ebay next stop...model yacht hulls.

Thanks Barrie,

Rich
