We hauled the boat out of the water today. Most of the previous antifoul had done a good job with only a lite slime considering the boat had been in the water for almost 18mths.
There were 2 stripes of excessive growth where it's either sat on a cradle and then had those sections hastily done as it was slung back in the water, or the slings themselves rubbed some antifoul off. Either way looks like someone at the previous marina didn't give it enough time to cure on the hard stand.
The rudder is curious. Why would there be so much growth on it? Was it again a poor job? Wrong antifoul? What about the leg? The prop wasn't too bad but the rest of the leg was terrible. The keel was fine.
My geuss is it was antifouled in the slings on a pre sale haulout .....what material is the rudder made from?
Yes I agree. The rudder may have had a rope wrapped about it or something and wore off the paint. Whatever it was the rudder needs more coats of paint. Such narrow rudders can cavitate or stall out and the bare patch is in just the right place.
The hull probably has been coated up in a copper based antifoul. The saildrive is always an issue as it must be coated in an aluminium based antifoul, so as not corrode the leg.
I amongst others, have not come across anything durable as yet that performs remotely well.
Volvo did have product in a spray can intended for sterndrives that was brilliant, but was taken off the market 3years ago.
Perhaps they(previous owners) may have used the same product on the rudder as per the leg that maybe a reason for the excessive growth there.
The prop looks to have been done in Propspeed which performs pretty good and hence why it's not bad.
Nice hull profile by the way. What brand of yacht is it?

After looking a bit closer, we think the stripes were where it sat on a cradle and then had a rush job as it was slung back into the water.
The rudder is grp. It's been sanded and re-primed as well this time so hopefully it will last much better.
The yacht is a Northshore 370, set up as just a weekend cruiser but really nice to sail.
Rub and polish on the gelcoat comes up a treat, hopefully get one more coat of polish on before it goes back in tomorrow
Oh, and I found the hull molds are for sale if you're interested.http://yachthub.com/list/yachts-for-sale/used/sail-monohulls/northshore-370-369-building-molds/132349
That keel must be a true delight when there are lumps of kelp drifting about or sailing past fish traps.
FR,
make sure the boss doesn't go up forward when on the slip like that, I'd like too see a prop under the bow somewhere.

Polish job looks very good, what do you use and is it hard to polish off without smears etc?
I didn't have much time with it on the slip so it was a fairly quick job.
First used starbrite medium rubbing compound paste - mostly easy rub on rub off by hand and did a good job on stains/marks/oxidation
Then starbrite premium marine polish liquid - very easy rub on rub off by hand.
I did first try using a 3m polish wax and power buffer but it was taking too long and I found it hard to get a good finish.
Ideally would have liked to get a second coat of the starbrite polish but ran out of time.
While out on the 'hard' ,it's always a rush getting a boat looking good on the topsides after tending to the 'big' issues below the waterline.
She is a fast looking cruising yacht and you have good shelter in the form of a decent bimini around the cockpit.
Well done-looks terrific and will serve you very well.
Would probably knock off a few punters around the cans now with the fresh bottom.
