MUMM36 ZAMBONI Bottom Job

The ownership group decided to take advantage of the Covid 19 delayed launch to completely strip the bottom, sand and fair the hull, and epoxy the bottom.  

The year after we got ACE, we chemically stripped the bottom of the existing bottom paint.
We sanded it down to 80 grit and have been applying VC-17 bottom paint every year.






Took about several weeks of sanding to get her done.  First with 60 grit, and then 120.


We got hit with some cold weather and could not epoxy until later in May.

We had to fair the keel and the rudder with epoxy fairing:


ZAMBONI was built in New Zealand is 1994, and delivered to Hawaii where she raced in the 150 mile Kenwood Cup for several years.

By May 17 (3 weeks to launch), we were ready to put on the Interprotect 2000 epoxy barrier coat.

We had to fair several gouges in the hull, and did one more sand with 180 grit.

First coat was with white was started in the late afternoon:



By 4:30pm, we started on the 2nd coat of grey:



By 6:30pm, we were putting on the 3rd (and final) white coat.



The following weekend, we did another quick had sanding with 220 grit sandpaper before putting on 3 coats of VC-17:








Did not take too long with two guys rolling it on.

We used 2 cans of the VC-17 bottom paint.
