I am preparing my small commercial fishing boat for the season and one of the main tasks has been to update the anchor equipment. We often work in strong currents and unstable weather conditions, so it is critical for me to choose an anchor chain that will be as resistant to loads, rust and wear as possible. The vessel weighs about 4 tons, the anchor is a plow type, weighing 20 kg, a Maxwell electric anchor windlass is installed with a suitable sprocket for a calibrated 8 mm chain. Do you have chains in your range that meet these parameters? I am also interested in whether you have quality certificates, recommendations for the minimum length of the chain for use in the coastal zone, and is it possible to arrange delivery to Portugal with a final price including VAT? I would be grateful if your specialist could provide technical advice before purchasing.
