Traditional Antifouling

The rich waters around our coast and particularly in harbours provide the perfect conditions for fouling boats. This fouling will slow the boat drastically as well as looking unsightly. A protective film is therefore applied to prevent this process.

To maintain the effectiveness of traditional antifouling it needs to be applied each year. At Haines we offer a variety of alternatives to our customers, depending on their needs and finances.

On suitable tides fin keel yachts can rest against the Harbour Conservancy ‘scrubbing piles’. A fresh water high-pressure hose can be hired, with or without Haines labour. The bottom is then cleaned and antifouled. The yacht is then floated off on the next tide.

There are a number of yard trailers available for all types of craft up to 9m and 6 tonne, which will give easy access to the bottom of the boat for both routine maintenance and antifouling.

New boats kept afloat during the season, require the bottom to be abraded to ensure a good key for the paint system. This is followed by priming and the choice of antifoul product.

There are 2 types of traditional antifouls, hard racing and soft eroding. As water flows over the surface of eroding antifoul, fresh layers of the active ingredient is exposed to repel any fouling. In hard racing types the active ingredient slowly leaches through the surface to prevent this fouling. Hard racing antifoul is also resistant to abrasion. Racing craft tend to prefer this type of antifoul as the bottom can be burnished to a very smooth finish. However, the nature of the antifoul is non-eroding and so the layers build up over the years. Over time this can add considerably to the weight of the craft. To maintain good racing speed, periodically, the bottom needs to be scraped back to gel coat before a new antifoul paint system is applied.
