serious anti foul questions

[rogerroger]

Last year the boat yard anti fouled the prop shaft and prop. They were the worst fouled at the end of the season - what the best thing to do?

Also - anyone know the difference between Blakes Titan and Tiger anti foul ?

I had 2 half tins left over from when the boatyard did it last year - would I be right in assuming they used the Tiger for the hull and the Titan for the keel and rudder ?

Blakes, do a very good (free) booklet which describes the differences and what should be used for what, any good chandler should be able to give you a copy if not I will look it up tomorrow.

I don't know how good Tiger is. I bought a boat antifouled with Titan on build in June 2000 and it is still holding up. Inspite of the extra cost of Titan over Tiger I am about to apply two new coats of Titan. I gues you get what you pay for. As for last year's paint it may be over shelf life but is probably still okay, the manufacturers never look on the bright side of shelf life in case of problems.
I never coat my prop or shaft, I usually polish them and grease them heavily. Never had much of a problem except the odd barnacle if you leave the boat stationary for a long period.

I polish my props, then apply as much as I can get on, black lead, its used for old type fireplaces and potbelly stoves etc. Just put it on and polish it, try as many coats as you can. It will stop anything growing on the prop, I also use hard racing antifoul on my bronze shafts. I admit my shafts are only turning at 600 RPM flat out! But its used extensively on the old gaffers working boats.

Blakes Titan - on sale at Yacht Mail, Lymington for approx £55 per 2.5 litres - saving about £20 on RRP.

AT LIBS, Blakes recommended Waterline (their scrubbable boot topping paint) for props, as it contains no metals. I'll give it a go this year, having been seriously disappointed with plain vaseline last year.

Seriously, the best thing to do is polish it, hard work the first time but when highly polished it becomes highly effective at keeping barnacles off.
The difference is £10, seriously the Titan is the stronger so you have it right, another interesting factor, you can launch the keel/rudder up to 1 month and the hull up to 3 months after anti-fouling.
PS evidently neither are edible!
All the best

Last year I tried lanolin (available at your pharmacist) on the prop and shaft and it seems to have worked very well. Very few barnacles and they scraped off with a pen knife. Will definitely use again, cheaper than A/F paint.

As it happens the whole hull was very clean so maybe it was a barnacle free year!

Quote from the Blakes booklet:

Titan FGA High strenght eroding antifouling suitable for areas of heavy fouling. A copper based antifouling with organic based biocides to provide maximum protection. The controlled erosion prevents seasonal build up. Suitable for use on all substrates except aluminium. Max launch time 1 month.
Tiger cruising Medium strenth copper based eroding antifouling provides all round protection in most fouling conditions. Formulated to ensure optimium antifouling performance throughout the season due to controlled biocide release. Suitable for use on all substrates except aluminium. Max launch time 3 months.

It would seem that there is only a strengh issue, ie more or less chemicals.

thanks for that. I've got loads of Tiger and only half a tin of Titan - might use the Titan for as much of the final coat as I can then finish with the Tiger.

She wasn't that badly fouled last year anyway, no weed nor barnacles, just a layer of slime.

thanks again!
