Slipped the boat today

Hi all

Slipped the boat today after 12 months in the water and this is what she looked like

I put on one coat of Hempel Olympic Soft with a second coat on the leading edges and waterline and all we had was slime and even the prop which i painted with the Hempel was clean as well

i think that this year she was the cleanest she has ever been so perhaps the water conditions have been favourable

Myself and a mate pressure cleaned her off including the deck,scrubbed and then wet sanded the antifoul, acid washed and polished the topsides and rolled on a coat of antifoul by about 2pm which worked out well as it started to rain around 3pm and she is ready to put back in the water tomorrow

Regards Don

Hi r13

That is the one I use but I don't think the Hempel is anything special it is probably more the location and the cold water temperature
where we in Hospital Bay at Port Huon is tidal but there must be a fair bit of fresh coming down the Huon and also the Kermandie River feeds fresh into the bay as well
I have used the same anti foul each year and normally slip her in September and each year is a little bit different but yesterday was the best I have seen

Regards Don

I used that Hempel a few years ago and it was hopeless after 3 months.

I left our cat at Kermandie marina for a year and there was almost no growth on her at all. The changes in fresh and salt water seemed very beneficial for hull cleanliness. I use a hardish antifoul that usually requires a scrub but in 10 months in the marina she only got a slight slime. Back in Lake mac, she gets far less out of her antifoul. Wattyl Seapro gets me about 18 months with fair bit of me scrubbing her bum. That is not hard on a cat like mine.

Got 5 years on the power boat there and could have gone longer.
In the end I had to lift just to check thing properly and replace anodes.
The change in salinity is why the salmon farms started there.

After slipping her yesterday I decided to do a couple of other jobs to get her up to scratch for the upcoming season

The birds bent the masthead wind indicator a few months ago so when we came off the slip this morning we tied her up next to my mates Walker H28 (HG'S old boat) and my mate went up the mast steps on the H28 and pulled my mast over to it and fixed the indicator

Then when i put her back on the mooring I decided to give her a engine service as well so now she has new oil and filter, two new fuel filters, two new engine anodes and a new raw water pump impeller

The anode on the starboard side of the engine was tight and a bugger to get to so I ended removing a steel fuel line and throttle linkage so I could get a socket and breaker bar on it and the one on the back of the head which I have had trouble undoing before came out easy

The CAV fuel filter and bowl was a pain to get all the orings to sit in the correct place and I would not like to have to replace it in a seaway so I am tempted to replace it with a spin on filter

The sump has a drain tap on it and it is the slowest draining engine I have ever seen so I stuck a piece of hose over it and let it drain into a bottle which took about an hour

The oil filler cap is under the cockpit floor with no room to use a normal funnel but the previous owner made up a filler tube that out of some tubing, a couple of elbows and a cut off brake fluid bottle that works a treat so filling it back up is easy

Finally got it back together about 6pm tonight after a couple of trips from to mooring to shore to get some extra tools and everything appears to be working ok

Good on you Don, difficult assemblies are often used as an excuse to, shall we say do it later.....
P.s I have found the the vacuum oil extractor an excellent tool for not only engine/ transmission oil change but its also
Happy to suck up oily bilge water , coolant etc

Hi Woko

I am guilty of that

I had all the parts I needed today because I bought them 12 months ago when i last slipped her but never got around to doing the engine

The last time we took her off the slip it was a nice day so we decided to go for a sail down the river where as this time my mate had to go to an appointment in Hobart otherwise we probably would have done the same thing

When I bought him in in the dinghy I went back out and took the raw water pump of her as it is easier to do at home and then it tool me a hour to find where I had stashed the parts and another hour to find my allen keys so I could remove the pump cover

The impeller kit had the correct impeller in it but the gasket was wrong so a called the Yanmar dealer in Hobart and they had the correct one and I got my mate to bring it back with him

I intended to do the pump first and then refit it and warm the engine to help the oil drain quicker but because I had to wait for the gasket I just drained it cold

A goof ip about the oil extractor as I always end up with diesel in the bilge water after I do the fuel filters
