I have been using ablative combined with a two transmitter ultrasound system & so far have had 4 yrs since coating. It has required some diving
rub down but has been economical. I am now thinking of using a copper based coating that says with minor annual rubdown (while in water
will) last 5 to 10 yrs.
As I am in my 71st yr it might see me out. my wife & I are very pleased with our vessel. Hope pix transmits was taken when in Sydney
prior to sailing to Adelaide in Sth Aust in 7.75 days.
