Just one more question! It is about the anti-fouling paint. I had saw the classic red-brownish paint, and also a green one (specially in russian and baltic navies, also in the italian navy in the years of wwii). The all black paint is very impressive both in military and civilian ships. But since relatively recent years I had found several paint schemes in blue (in fact, your blue is the deepest blue of all the shades). Is this a new trend? The blue pigments are better to counter the seabugs? Cheers and once again, thanks.

PS: and my appologies for the off-topic!

I've seen pictures of blue anti-fouling paint on the USS Port Royal, and a quick google search shows that they come in a surprisingly (for my uneducated self anyways) number of colors.

I gotta say though the blue on a Tico looks really sharp. Too bad nobody but the fish can see it.

Yeah does anyone know the reasoning behind different anti-fouling colors? I've always just used the non-red versions as "modernized" anti-fouling paints without really knowing the justification. ;)

Google the shit out of google and get random things like this:
Quote:
Darker colors tend to have a higher copper content, as copper tints the paint.
Quote:
The relationship between antifoul paint and topsides is an important one
Quote:
I've noticed that in clean, hot, tropical water that white antifoul performed better than red, black or blue.
Quote:
In modern times, antifouling paints are formulated with cuprous oxide (or other copper compounds) and/or other biocides—special chemicals which impede growth of barnacles, algae, and marine organisms.
cooper might affect the color of the anti-fouling paint.

Color
Yachtsmen frequently choose the color of their
bottom paints for esthetic reasons. Since the best
toxic pigments are not of the desired colors, particularly
the greens, many inferior yacht paints
have been produced for this trade. Bottom paints
used on work boats of all sorts are not usually
especially colored. Submarines are frequently
painted black for tactIcal reasons. The introduction
of the tinting pigments commonly impairs the antifouling
effectiveness of the paint. A similar problem
is introduced in flying-boat hulls, where the
need for a pale color has precluded the use of
cuprous oxide, the toxic most approved in antifouling
paints for ships.
Color has also been considered an important
factor in determining the degree of fouling on
submerged surfaces

There was an another forum here in Norway, that was talking about it. but they are under service at the moment. But I have noticed that black antifouling here in Norway have a better survivability than other colors. for example my boat has black antifouling, and it have been on the water for 3 years straight, and there have never grown anything on it, except at the inlet!

Usually just for looks and contrast, for commercial ships it's aesthetics, for naval ships it's probably what mix they know works as well as minimizing visibility when riding high. Certain compounds can affect the end shade but not too greatly I'd imagine, all I know is it makes a very pervasive dust when being removed


I have seen pretty much every color there is of antifoul except yellow and purple, they make white and grey now as well

On the civilian boat market, probably just aesthetics.North Point Marine down the street is full of boats with various below the waterline colors. As for military, someone on another forum said it was a silicone coating, not traditional paint, and that it was commonly applied to east coast Ticos and Burkes, but they provided no references to back it up. *Speculation* it's possible they were trying new antifouling materials that would either be more environmentally friendly, or reduced drag compared to typical paint?

Edit: found a press release from the Navy:

Three protocols:The mast is too high,it may cause high center of gravity;The helicopter deck is too small;The rear Phalanx CIWS obscured SPG62 radar.

I don't think this is a suitable design,unclear position,too expensive.
