BARNACLES

[davedpc]

What good is modern antifoul on the outdrives,especially in the harsh envoirment of the upper Hamble river. Ive tried all the usual rubbish only to find the little Bastards cling on within a couple of months. The hull I find is O.k This time im going to clean all the old Micron antifoul off the legs and polish them up. Then im going to coat them with Lanolin available from the Chandlers for about £6 a tub. Has anybody had any experience with this grease ? Bring back T.B.T.O. Dave.

For some reason barnacles like metal, even with copious amounts of antifoul, my shafts props and rudder are always covered in them, even with three coats of proper antifoul, (Broinzw props, shafts and rudder). the hull is fine!

The hull is fine

Thats cos most of it crumbles away just as the buggers start to get a grip! Time for you to get a proper plastic boat like everyone else. Gribble, toredo(?), rot, thank goodness we've only got osmosis.

Re: The hull is fine

Dont get gribble, toredo, or rot! Cascover sheathed from new, to 6" above waterline and built of teak!! all underwater fittings made of bronze! Remember the polyestermite! forgive me JDS!!

" For some reason Barnacles like metal"


Well if you were a mollusc with sensitve feet, (or foot in Barnacle case) would you stick your size 10 on a rough surfaced sharp rocky outcrop, or the side of a smooth shiny flat hull, where you can get plenty of adhesion without been washed off.
They are just gonna hang there waiting for the tide to bring in their dinner!

But why metal, mine is not shiny, its covered in nasty antifoul, same as the hull, they dont like the hull?

They don't give a damn. The larvae float with the tide until they land on a suitable hard surface. At which point they make it home, and either survive or don't

I wonder if it might be possible for outdrive manufacturers to design a system that discourages barnacles?

Two possibles that spring to mind is that flat metal surfaces are machined in some way such as grooves or pimples as barnacles seem to prefer something smooth to stick to. Or maybe an electrical charge or something ultrasonic?

Shouldn't be beyond the realms of modern science to upset the little buggers enough to go elsewhere!

I moor on the Itchin and have the same problem, except that I am on shafts. Nonetheless, the shafts, rudders and props suffer from barcacles. I spoke to Blakes at the boat show; they have just introduced a new spray-on antifoul specially formulated for sterngear and props which they reckon will solve the problem. Comes in an aerosol can. Don't know whether it is any good but going to try it this year. Probably won't help with outdrives, but hoprfully will solve the sterngear/ props problem.
