3ft deep band of the buga's at the stern.. and no way was I going in the water with Tiger sharks prowling the anchorage...
For longer passages, we picked up this trick: thin-ish floating line tied as far forward as possible and dragging alongside the leeward edge. Leave it out for, oh, no more than than an hour. (More than that and you'll start wearing away the paint/hull...} Wave/hull interaction bounces the line alongside and knocks off gooseneck barnacles and whatnot before they get a solid grip - especially the above waterline hull that ends up below waterline for days on end.

We did this on passage from Mexico/NZ, using 3/8 line - worked a treat and we were clean along the sides. BUT, it doesn't get ALL the way under the stern. Dinghy and metal putty knife on a stick for that part. Tough guys, those goosenecks...

Unless your spatula floats don't forget to put a wrist strap on it. Also wear gloves or you may end up with some missing skin.

Re: Holy Arthropods Batman, We Have Barnacles

Robyn,

You're wise to worry about what gets in your ears while hull scraping. You can end up with a bad case of "swimmers ear". That happened to me. Try rinsing them out with 50:50 isoproply alcohol and white vinegar. My doctor recommended that to me, and it works. I kept a solution in a squeeze bottle with a spout, which made it easy to do.

I am surprised you got barnacles over 66. Are they of the goosneck brand?

I am asking as we got plenty of barnacles over Hempel (Mille) Dynamic, but none over 66. We painted 4 layers, 7 in the much light/much wash areas. But, being in different oceans, it is so hard to compare anything.

Cheers,

Hi B,

I thought you might find this info interesting, maybe helpful.

I just heard back from Island Marine in Puerto Rico (they did our bottom paint). Ken reminded me that after the bottom was done we had the boat hauled twice. The first time was two months later after an embarrassing incident involving a concrete dock, we were out of the water about ten days -- please remember boys and girls, never go faster into your slip than you want to hit the dock! The second time, it was hauled for three months while we went home for the births of two new grandsons. Anyway, Ken is wondering if that hasn't had an effect on the performance of the paint, because his experience is that what is happening is unusual.

Hope that info helps.

Robyn

I read somewhere, years ago, I can't remember where, about rinsing your ears with vinegar. Thanks for the reminder.

So this morning I have six little crabs hanging out on the lip at the stern. Looks like we have started a crab nursery!

Re: Holy Arthropods Batman, We Have Barnacles

Never had bottom paint that worked good on the Atlantic/Caribe side...(Annapolis to Trini) other than the US banned stuff avail in Trini. It actually worked! Pacific seems much slower growth for some reason. (mexi and north)
Most of the paints seem to kill the barnacles eventually, but what's the point if they are 3/8" diameter and stuck to the hull dead anyway?
The black Dutch "submarine paint" from Trini kept them from growing there at all.
