Reminds me of a time in the 60's when a well known paint company did a freebie on a big yacht called "Christina" in the hope of getting lots of work from the owner. The boat was due to got into the Med but went to the Bahamas first. When it arrived in Gib the company I was with at the time were employed by the paint company to do "survey", which meant cleaning the odd bit of growth and saying how well it looked. Unfortunately the hull was completely covered with crown barnacles. Moral ... get the anti weed one, assuming they still make different ones
This is one of those 'how long is a piece of string' questions.
If you are cruising full time, moving every two, three or four days, then almost anything will be OK. We have used a different one every year, including some old International Cruiser Superior, some stuff I bought direct from a dealer in Palma Mallorca, don't remember its name, Seascrew's very cheap stuff and some Italian product that they had in the chandler in Bastia. All have performed extremely well, requiring only a wipe of my hand about two times per season to remove a little slime, although the fish have contributed as well. Occasionally a small amount of shell has grown in the more shaded parts around the rudder but these are easily removed with my fingernail. This year I will use the Greek A/F sold at Preveza, which has received good reports.
On the other hand, there are plenty of stories of boats left for a month at Nidri that were so badly fouled that the propeller would not rotate. I saw one in Sardinia (yes I know that's not the eastern Med) in which there was no daylight between hull, rudder and prop, after one mostly static season and winter.
It's cheap enough to get a lift out and a pressure wash. Am now thinking of doing this twice a year to save the labour of anti-fouling every 12-15 months.
I applied a local Turkish antifoul; Teknomarin, in March of last year. I sailed a lot until end of October but after that the boat has been lying still in the warmish waters of Marmaris until yesterday. 5 months and almost not a single growth. I dived under the boat today and I could not believe it; almost clean. This stuff is clearly not 'environmentaly friendly' but it works. Fantastic! In my first season in Turkey I used Cruiser Uno and the hull looked like a rainforest after a winter in the water. I can recommend the local Turkish stuff.
I paid two local guys 400 euros for the job, including primer and the antifoul in two layers. Great value!
Thanks for that LadyJessie, I was asking on behalf of a friend who is in Greece and heading for Turkey so that will be handy. You ought to come out of retirement and import Teknomarin into the UK - I know I could find a use for it.

[/ QUOTE ] Beware - different growths affect boats depending on salinity, temperature, frequency the boat travels, and any particular local effects.
So, usually, the best antifoul to use is the local fishermen's choice - as long as you use the boat at least once or twice a week.
Nidri was quoted above as a place creating heavy growth. True. Similar in Levkas town. Very muddy bottoms, shallow waters rich with nutrients. Even worse in Vliho bay. But go to a clear water area . . .
