Around 50 people attended workshops in Nelson and Picton over the weekend of 24 and 25 May 2019 to learn more about the why's and do's of keeping the hulls of recreational vessels clean of harmful marine organisms.
The workshops were a collaborative effort by the Top of the South Marine Biosecurity Partnership and Carboline Paints trading in New Zealand as Altex. The workshops were supported by the Nelson and Marlborough Councils, Port Marlborough and Nelmac as marina operators.
At Waikawa and Nelson participants were provided with information on marine biosecurity and shown the sorts of things that will grow on an unprotected hull. In each location a fouled vessel was lifted and partly cleaned. Marine experts explained the role of vessels in transporting pests and weeds around New Zealand.
Altex staff provided information on the best paints to use for different vessels and how to prepare a vessel for painting.
Paints have changed
Old timers were surprised to find how much paints had changed over the years and what a difference correct preparation and application of anti-fouling could make. Really good work was being rewarded with more than two years of trouble-free boating while a poor job could have a vessel highly fouled in less than 6 months.
With the advent of ablative paints where the surface wears away to expose more active ingredients, vessel use has become even more important. The same paint will not suit a yacht that travels at 7 knots and a high speed launch that may exceed 50 knots.
Carboline provided a prize draw and two lucky boaties have their paint ready when they haul their vessel.
Top of the South regional Marine Biosecurity Coordinator said "we were happy with the turnout and the high level of interest shown. Having the paint experts there made a big difference and they easily handled all the tricky questions thrown at them. We would definitely do this again and would be happy to take the event to other locations in the Top of the South if we get requests."
