I guess it depends on location, paint condition, but mostly quality of bottom paint. Sometimes the oatmeal dries and nicely flacks off.
I use a multi-season ablative Pettit Ultima SR-60. It costs about $300 a gallon but it is a real performer in the FL Gulf area. When I last hauled out Dec 2017, the bottom paint from Sep 2014 was in pretty good shape. There was only a few barnacles along the waterline, but the what was green bottom, was covered with a black slim. It was late in the day, and the marina was in a rush to get the boat placed in the blocks, so I opted to skip the pressure washing. It was several days before I started working on the bottom, and to my surprise, the black slim had dried and lifted from the hull. I removed it easily with a stiff brush, revealing green bottom paint below. I sanded the whole bottom with 80 grit on an orbital sander, rinsed off the hull, and the next day applied the 1st of 2 coats of the same bottom paint. The boat has now been in the water for nearly 4 years and still looks pretty good. Again, I have the black slim, some barnacle growth along the waterline, which I clean about every 3 months. It looks like I get another year or hopefully two. But when I do haul out, I will not be pressuring washing. Not all is good. I do have a real problem with hard barnacle and oyster growth on the prop, shaft, and transducers. I tried many of the props paints, lastly being Velox Plus, but nothing seems to last over a year. Open for suggestions. I may break down for some propspeed next time. - Paul E. 1981 C&C Landfall 38 S/V Johanna Rose Fort Walton Beach, FL http://svjohannarose.blogspot.com/ > On Sep 28, 2021, at 4:53 PM, Bill Coleman via CnC-List > <cnc-list@cnc-list.com> wrote: > > Think about eating a bowl of oatmeal, leave the bowl on the counter for a > couple weeks, vs put it in the sink with water, and clean a few hours later. > So yeah, You want to get to this muy pronto. > > > Bill Coleman > Entrada, Erie, PA > > > > From: G Gao via CnC-List [mailto:cnc-list@cnc-list.com > <mailto:cnc-list@cnc-list.com>] > Sent: Tuesday, September 28, 2021 4:33 PM > To: Stus-List > Cc: G Gao > Subject: Stus-List bottom wash > > Hi, > > Again a simple question that I have for experienced sailors. > > In the past I have had the marina to "bottom wash" my boat when they do the > haul out.
