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>
