Malaya has finally been hauled out and set down for the winter, as expected her bottom had pretty heavy growth and that spells the end of our experimenting with paints that don’t have copper in them.
Last year in July I applied 3 coats of Pettit Hydro-Eco, a water based non copper ablative. It started growing grass within 4 months and by 6 months had a pretty good crop of grass. Attempts to scrub it off resulted in too much paint removal so I gave that idea up. Sailing on passages helped a little but we never were able to get rid of the grass and later hard growth.
Two hours with the pressure washer at haul out took off the Hydro-Eco along with some older paint and exposed about 1/4 of the original Interlux Interpertect 2000 barrier coat. Since the barrier coating was applied 8 years ago and has a life of about 10 we will vacuum sand with 60 grit to remove the rest of the bottom paint and prep the surface for a new application of Interpertect. On top of that we will apply 3 coats of a copper ablative paint. Which brand is still to be determined.
On the prop I had sprayed Pettit 1792 Prop Coat Barnacle Barrier, at $25.00 a can retail, it was well worth the investment. I applied 3 coats to my prop in July of 2016. Since August of 2016 we have sailed and motored over 5000 miles before arriving back in Gloucester in June of 2017. Since are arrival home we have been on a mooring or at anchor and only sailed or motored a half dozen times. No growth on the prop what was noted during our cruise, the amount of growth on the prop at haul out was insignificant though it was evident the prop was ready for 3 more coats of Prop Coat.
In a day or so we will be posting our work list for this winter and spring, some items will likely not get done until summer. We hope to take lots of pictures and hope to make some video of the projects so we can pass on repair and service info. Stay tuned.
