Chrs Guys all good input, good point about the cable run.
Its a quantum 2 microwave model and so does not have a magnetron.

Morning folks.
We are upgrading our radar from analogue to digital (Raymarine) and the current transponder is on a pole bolted to the transom. As we have recently added a boarding platform and want to free up access space we are planning to move it to the mast .
The geometry all checks out so it will fit ok with adequate sail clearance etc.
I would be interested to hear of the pros and cons with having it on the mast as opposed to the transom. Matt ..........?

Thanks IT, to use gold would be cheaper... However it is on it's way now.
I tried something cheaper called NyOil and regretted it big time, it swelled with submersion and almost completely froze the rudder. Replaced with Vesconite.

Morning all, I have a seawater cooled Vovlo MD7B, (3000 SERIES ?) long story but I had to take the thermostat out of the watercooled exhaust manifold. I cant put a new one in due to corrosion damage but the manifold is fine otherwise and they are eye-wateringly expensive. The motor did not seem to mind and still came up to temp but perhaps a bit slower, no biggie. However I recently replaced the impeller and now the flow is such that it runs way too cool. Clearly the old impeller delivered a degraded flow that was nevertheless about right.
I have a digital temp module with an alarm so i can monitor it accurately.
I was wondering about putting a second valve in the inlet line as a partial restrictor and then experimenting to reduce the flow to get a good balance again, thoughts ?

This guy might be useful too, he is in Auckland

Commiserations Matt,
Small consolation but at at 10,000 hours you have had an outstanding life for that motor.
Also a head job will push the restored compression to the next line of defense, ie the rings or block, so its perhaps more than co-incidence to see this, post OH if there was a latent defect.
We recently had a self inflicted fuel supply blockage with our Perkins 4108, found that eventually and fixed it, meantime had half the system apart which caused failure of the Racor primary filter selection cock, 2 more weeks to suss that, 4 weeks later we are back in business. The silver lining is that we now know the fuel system back to front !

A selection of Jubilee clamps, a tube of the red high temp RTV and a few short hose pieces , have saved my bacon a few times.
Also some cheap electrical choc block
If you are racing weight is a consideration, here's few items that I think are must haves;
Hacksaw plus spare blades- rig removal
ball peen hammer- useful for persuasion
spanners to suit bolts on board usually a few small ring and open enders for fittings and an adjustable
good quality sidecutters- electrical work, rigging wire
vice grips, std and/or small needle nose- very useful as second pair of hands
needle nose pliers- generally useful
screwdrivers to suit
punch or small drift, removing pins
Tape, electrical and duct (3-M)

Fitted new boarding platform, Raymarine triducer and sanded the hull for antifoul. Parrot dog at 6pm fell asleep watching Netfix.

Thanks for the suggestions !

Anyone know of a high density foam i can use to shape a hull transducer mounting pad ? The alternative is to use a hardwood like iroko or Jarrah then epoxy seal etc. I thought the foam might be more stable.

What do you think Matt ?

The broker at Opua told me they have a particular problem with oyster growth on hulls something to do with the oyster farms abandoned a few years ago.
-
Got the right boat for it
-
Sounds like they were rolled by a rogue wave, whats the bet the boat is still floating?
-
Rosenfeldt and Kidson have Iroko, its not particularly expensive for an exotic hardwood, I used it to replace some teak grab-rails

Stunning Interior and If I ever Built another boat, I would steal with pride some of her features. On the flipside if you like wood but not the maintenance that goes with it go for GRP and then go cabinet maker crazy inside.
Plus a carvel hull in the 1990's ?? gawd if you are a fanatic wood- o- phile at least do strip plank or cold moulded.
30 hp seems hopelessly underpowered for a 53 ft yacht that must weigh 15 tons or more, I'll concede they have the track record to prove it was adequate, still 100hp sounds better

Here is the link to the topic of the sinking / rescue
In that thread, there are various links to his blog page, face book page and news stories that give a lot of insight into his trip, and the cause of failure.
Excellent , thanks for that !

I have read recent news articles on the unfortunate loss of Waimanu, a Townson 32.
It seems that she was punching into a decent sea and a shroud let go, then the collapsed mast punched a hole in the hull etc.
Can anyone confirm the point of failure of the shroud ie, was it that.....
- The chain plate tore free of the hull.
- The hull structure failed around the plate
- The chain plate fastenings failed.
- The wire parted at the swage or failed in itself.
Just curious as it may have implications for other boats of a similar vintage and construction.

We bought a 38 ft ocean going Yacht in very good nick. 140K. Even so it will be 160k or more by the time it's back in blue water mode.

- Relatively fast (i.e. can plane) Will get a boat that surfs but actual planing? Even in that last winter series race when it blew 40 plus for a time, hardly anything planed properly.
- able to be single handed, 34-40ft Yes any boat in that range.
- some cruising up to the islands Yes virtually anything that weighs 5 tons or more but the better it is at cruising then the less of number 1
- coastal and harbour racing (AKL) Yes
- 60-80k range. Hmmmm
- He's tired of DIY... Earth to Dr Watson, its a boat!
Young 11 (rough) or a Farr 38 (Protocol was asking 70)

I think you need to narrow it down a bit as that is actually quite a big size bracket and so price range as well.
If he is tired of DIY and does not want a Shitter then he should get a well equipped and maintained 32 to 34 ft GRP vessel for that sort of money, nothing bigger in my experience.
