Re: Bottom paint on prop

This came off our hull,at the dock in Annapolis:


Diver said this fuzzy stuff is the worst he's seen ever.

We have prop speed on the prop, he said he was able to brush the growth off easily with a gloved hand. Re our copper bottom paint, he again said it was easy to remove the growth. The copper paint didn't slow the growth tremendously compared to other types of bottom paint, but the big advantage is that our diver said he has worked on boats with this paint that have been eight years since their last bottom job. The paint cost us about $550/gallon, and coverage was equivalent to other bottom paint. So in my mind, the first time that we don't have to haul and redo the bottom, we're money ahead.

Re: Bottom paint on prop

I dunno- looks to me like your $550/gallon anti fouling coating isn't doing much of a job.

Re: Bottom paint on prop

Fastbottoms - The growth was similar in quantity to the growth on other boats, but somewhat easier for him to remove than it was on boats using other kinds of paint. That translated to less underwater time for him, less cost for me. If, in addition the paint lasts 4 times longer in our location than other kinds of paints, fewer haulouts, again, less cost for me. And our boat sails faster with it than with our previous (ablative) paint. All in all, it seems to me that it is a substantial net advantage to me to have invested in the copper paint.

There is a 'brown baby barnacle' infestation this year on the bay - everyone regardless of paint type is getting covered. Wipes off easy, but only if you keep at it.

What length of time had elapsed since the previous cleaning and the one illustrated in your pic?

Wingnwing should post a pic of what a diver scrapped from their boat docked in Annapolis, it was unbelievable. I have been trying to find a report that might explain, the only thing I have seen is refering to the bays health, which BTW is reported to have improved last year to a grade of "C" or "C-"
For the past 3 years I have used Petit Zinc Coat transducer paint.

The first two years it seemed to work well, as I had minimal growth. Here is a pic that a diver took of my prop in September of 2011 while changing a zinc;


This year, however, it seems to have done little, if anything to stem the growth of the little buggers. I dove on the boat this past week, and it looked like 10 grit sand paper...

I believe that the issue is the warmer water that we are experiencing in Narraganset bay this year. Water temp is close to 80F already.

Re: Bottom paint on prop

Clearly this year is different on the Chesapeake for all manner of critters. So I'll be the guy diving on his prop out in Herring Bay this weekend wearing his makeshift jellyfish armor: bicycle tights and long sleeved t-shirt

Re: Bottom paint on prop

This from one of my previous posts:

My boat comes out in two weeks and I'm going to try it but unfortunately it will be two years before I can reliably report back.
So that's what I did and in August last year (8 months ago) I had the prop done by the Propspeed agents in Auckland. And I didn't have to wait two years for the results.

Whilst I haven't used the boat extensively, I did a 5 week local cruise over December/January and have been sailing at least one often twice a month. And slowly but surely the boat responded less smartly to engine power.

A month ago, after the agent being told that I had barnacles gathering on the prop, he said "Don't worry about what's on the prop. Stuff gathers but the first time you run the prop, everything will just fall off."

Well this weekend we went for a sail and the boat was sluggish beyond belief under power and whilst I haven't been under, I suspect the prop is once again, just a ball of sea-life.

I plan on taking a picture of the prop to show the agent so that I can get him involved in the $400 cost of hauling the boat and re-doing the Propspeed as per his guarantee.

I shall post that picture here too.

Suffice it to say I'm really disappointed.
