Antifoul

[Killick69]

I am starting to plan the next antifoul of Night Cap. This time round I will try Altex #5 (have used Micron extra last 2 times). Likely will do the job early August.

Anyone interested in sharing 10 litre can of Altex no5. That will be $185 each for 5 litres. I am in Berowra and will slip at Fenwicks in Brooklyn. If one can get the antifoul on the Whitworths boat show special, it will be be even better than $37/litre. In the past I have found 4 litres Micron to be just enough.

Cheers, John

John,
Why have you decided to try an alternative to International Micron Extra? How long did it last?
I have been using Jotun SeaGuardian for the past 4 years and have got 18 months out of it - with some minor brushes by a diver. I have also looked at Altex No 5, but was considering trying Micron Extra this year. Your feedback would be appreciated.
Thanks,

I believe rate and extent of fouling is very dependent on location and other factors. It seems the area where Night Cap is moored, namely Parsley Bay on the Hawkesbury is an area where fouling is severe. I was hoping to get 18 months from the last application of Micron Extra, but in reality it was effective for 12 months (and possibly a month or 2 more). It was almost as if there was no/minor fouling, then about the 12th month things changed dramatically. I applied the antifouling correctly, proper prep, stirring the antifoul regularly, even application, 2 coats and a third coat over most of the leading edges, until I started running out of antifoul paint. I have spoke to a few marinas and shipwrights in the general area and they all told me they use Altex no5, because it is the best/best for this area. They by and large mentioned that Micron Extra is more expensive. Perhaps they are $ driven??
I decided to try the Altex and see how the 2 compare and hopefully I will get 15 months out of it. I have tried really hard to ablate the antifoul and most weeks would get to the boat, even if only to motor for half an hour to expose fresh surface. Hope that helps.
Cheers, John

Mark,
Happy to share 10 litres with you.
Have sent you PM. Suggest you phone me or send message.

Hi Kevin,
Is the Jotun SeaGuardian a hard or soft antifoul? Seems you have had good results with the Jotun, why change??
Do you think the minor scraping by the diver has a big impact on the longevity of the Jotun??

I have not been able to work out if brushing/scraping of ablative A-F is a good idea.
I brushed after the A-F stopped "working" and then went on to scraping, but with poor results. I guess there is virtually no active on my boat now and the growth is accelerating.

Cheers, John

Mark,

I think my PM to you did not go. It read 'sent successfully", but is not visible in sent messages (however, is visible in Outbox).

Perhaps you can PM me your contact details, if you did not get my mobile no.

Cheers, John
