Bottom job
Hi Steve, Congrats on the new boat. Get ready to start spending your kids inheritance. Assuming the bottom is in good shape,(smooth with no flaking or bare spots.) I would just skuff it up good. 80-100 gritt on a palm type sander. (messy job, wear a mask and disposable tyvek suit!) Your goal is not to sand it down, just ruff it up then wash it down, boat soap (no wax!!) and water. Does she have an inboard? If yes your shaft zinc has to be on bare metal. Sand the area for zink for good bond. We always use a multi season abalative paint. (micron plus) With that we don't even get slime! I would leave the existing paint as your base coat then apply two coats of a different color. (one coat if you haul each season) We haul every two years and stay in year round. We use black over blue. Now you don't have to worry about the bottom till you start to see traces of blue. When you do just remember it's allmost time to haul and paint again. One more tip, we always paint an extra coat on the leading edges of the keel and bow and an extra coat on the rudder as I believe these areas are subjected to more wear. If you are in salt water, don't be afraid to paint up inside thre hulls and don't forget the paddle wheel for knot meter. You don't need any special Transducer paint. Last but not least save some paint so when the yard lifts her to launch you can get the bottom of the keel and where the jack stand supports are. This paint won't be dry, don't worry. It sticks and still works. Enjoy Paul & Valery alkaid@msn.com

Congrats Steve!
Hi Steve, Welcome to the proud group of Cherubini Hunter owners. I concur with Pauls advise. Did you have the boat surveyed? You might consider joining the SailNet e-mail list for Hunters...lot's of good discussions. I wrote an article on the Cherubini Hunters, for a magazine. I could forward over to you if you send me your e-mail address. Don sailbode@gis.net

Strip?
Are you sure you need to strip? I took our H37C down to bare gelcoat, very big job. Most would recommend sand or bead blasting. Being overly cautious and very cheap I opted for a couple of different sizes of paint scrapers. I filed off the corners so as not to gouge the gelcoat. I covered the ground with plastic tarps to catch all the scrapings. But much better than sanding, no dust just lots of large flakes. Had to had sand a few spots after I finished scraping. Then five coats of Interlux 2000E, an epoxy barrier coat and she was ready for bottom paint. I like Trinidad SR, a modified epoxy that dries hard and fast. Only real advantage of starting with bare gelcoat is to repair blisters. Or, in my case, to make sure I never have to.

Why?
Steve: I'd have to agree with the other posts. There are not too many good reasons to strip off the old paint. If you really want to do this, you may want to look into a product called Peel Away. It is bastically paint remover with a paper covering. You apply the remover and apply the paper. Let it work for 24 hrs and MOST of the paint should be removed. If it doesn't you may need to do another application. They have this stuff in Marine stores but you may also be able to find it in a home improvement center (cost a lot less). Figure out why you want to remove the old paint and then consider if you really want to do this or not.

follow up to preping of hull.
Perhaps stripping is the wrong word. I thought the idea was to get a clean surface. There exists anti fouling paint and I have been told to apply another coat. As suggested, perhaps I just rough up the existing paint and put a new one on? Thanks for your input everyone. Steve (a new boat owner and sailor)

light sanding.
Steve: Our bottom gets painted about every 3 years. When the yard pulls the boat they powerwash the bottom and clean up and bad spots they tape it off and slap on the new paint. Clean up and drop her in the water. They do not even bother to sand the bottom (environmental hazard, don't you know). It seems that it is okay of the junk sloughs off in the water but not on land (go figure).
