don't claim to be an expert in paint by any means, however, my very basic
understanding of ablative paint is that it falls off as time goes by.
That it does not necessarily inhibit growth but instead, growth on the paint
falls off with it over time. Further, this is the reason ablative paints
need to be renewed regularly as, once all that was put on has fallen off,
nothing remains to prevent growth from building up on a
bottom.</SPAN></FONT></DIV>

PM<BR>Subject: [Santana 22] How To Wet Sail and Be
Fast<BR><BR>Summary: Ablative paints are SLOW. Get a sprayed
hard bottom. Your bottom is only as good as the prep work, spend an
afternoon fairing it with a 3M fairing board.<BR><BR>I think that there are
a few people in our fleet who have been unduly frustrated in their quest for
speed. Faired keels, new sails, and years spent sailing still leaves
the top of the fleet out of reach. I personally think that bottom work
has done more to take me from being consistently last in the fleet than
anything else, including new sails. <BR><BR>Many of the wet sailed boats,
including mine when I got it, have a traditional ablative bottom
paint. This paint is soft and rough. Even though I was cleaning
my old ablative bottom before races, it's cratered surface was never going
to be fast. From what I understand, this type of thing is very
difficult to avoid with an ablative bottom as the paint gradually flakes
away. <BR><BR>A hard paint will maintain a smooth surface over the life of
the paint job and not flake off like an ablative. You will also be
able to to give it a light wet sanding with 600 grit to make it super smooth
before it leaves the yard. <BR><BR>Steps:<BR><BR>1: Remove all of your
old ablative bottom paint. It will bleed through and screw up your new
hard paint. This is a must first step.<BR><BR>2: Your bottom is
now down to gel coat, spend a day or so going over it with a long board. If
there are any divets etc... Fill them with fairing compound and sand
them smooth. The end product is only going to be as good as the effort
you put into this step! <BR><BR>2.5: You may need a barrier
coat. Talk to your yard or paint manufacturer.<BR><BR>3: Pick a
hard bottom paint and get it sprayed on. Get it sprayed. Sprayed
is smooth, sprayed is faster.<BR><BR>4: Give your bottom a light
sanding with 600 grit after it has dried. Light, we don't want to take
too much off. <BR><BR>5: Clean your bottom before every race you care
about doing well in. And make sure your diver is treating it
well. Pettit vivid should only be cleaned with smooth carpet, I
think I am going to use a sponge this year. <BR><BR>Paints: I
personally like Pettit Vivid because it comes in white which is easy for me
to clean. Michael Tosse at Svendsen's recommended Proline 1088 with
graphite mixed in. Kim Desenberg at KKMI says they like Micron 66
which he thinks is harder than vivid. I'm sure there are other
solutions. The key is to get a hard paint and prepare the bottom well.
<BR><BR>Tools: 3M makes a great fairing board. It made a huge
difference when I was working on my keel. I have one that you can
borrow.<BR><BR>Don't let your yard push you around into doing what is
easiest for them. If you have questions ask the list. <BR><BR>Finally,
I want to point to the results at the last Scombridae Sunday. Kevin
McElroy and his brother Darren got 3rd of 8 boats in the after lunch
racing. I know that Kevin only got the boat last fall and just started
sailing a year and half ago. This was the first time he had raced the
boat. He just got a sprayed Vivid bottom (yellow as you may have
noticed) and cleaned it that morning. Old sails, no rockstar crew,
just some hard work in the yard and a smart young man at the helm. <BR><BR>I
think that getting the right bottom on the wet sailed boats in our fleet
will make the racing tighter and more fun for everybody.
Clarifications, corrections, personal experience... let us
know.<BR><BR>Pete</SPAN></FONT></P>
