Does any one have any suggestions for bottom paint. I have a 92 17OR with a 115, new for me. The bottom is currently bare. I havent made up my mind to leave it on a morring or trailer. I have seen alot of paints that wern't around 15 years ago when I laste painted a bottom. thanks Brendan

I have no idea what a '92 170r is but this paint may be of interest. Dolphinite has an new bottom paint that has a gloss finish. It is available in some traditional colors, some not so traditional colors, and clear. It has no biocide so it does not kill marine organisms, it prevents them from attaching to the hull. One applicatoin should last 2 seasons. It's unproven and expensive but if it works it will change the way we look at bottom paint. I plan to try it this year.
If you want to go with a more traditional paint, definitely go ablative. It will cost a little more but you'll get a much smoother finish. It's also easier to reapply. Petit Horizon, or Interlux ACT are lower priced ablative paints that are good performers. I've also had some good luck with the West Marine house brand. If you keep the boat in tropical waters you may want to use a high end paint like Petit Trinidad or Interlux Micron 66.
whale on!

I have used Interlux Micron CSC Ultra with great success.

Sounds like a 1992 17' Boston Whaler Outrage with a 115 horse power motor;) Where would this boat be kept? Cold/warm water?

I'm currently in the painful process of removing the paint from my 18OR. I would suggest NOT painting the boat if you are not going to leave it in the water for EXTENDED periods of time. Once you paint the bottom it is there is no room to change your mind.

Thanks guys It is 1992 Outrage. I Live in Maine so I regard the water as more sub-artic than anyhting else. I am leaning more to leaving it bare and seeing how that goes as there is almost no way to go back once I've painted it. When I was a kid I had a 13 ft Whaler and always painted the bottom. I realize growth is a regonal thing but how long do you guys think it can be left in without the paint before growth start?

If you are leaving the boat in the water then you should paint the bottom. I put one coat of petit bottom paint color red, then 2 coats of thier ablative with slime control in black. When the ablative wears though you will see the red and know to put another coat on.
Seems to work fine for me.

There is another reason to paint the bottom. If the boat is going to be in the water for extended peroids, then the epoxy barrier coat that is applied before the paint, will help prevent osmotic blistering.

Even in Maine, I wouldn't leave it in more than a week or two without bottom paint. You can apply a teflon based wax to the hull to make it more difficult for barnacles and mussels to attach themselves, but once they do it is a lot of work to get them off. You can always haul and scrub or do the swimming scrub once a week.

Outrageman is on the money.... Micron CSC/Ultra is well worth the money. A gallon will cost you about $160.00 but... it will last for years, just touch up the bare spots between seasons. It's amazing how well it works, if there is any growth on your bottom, a simple boat ride will aliviate it, the paint(and whats on it) wears away like a bar of soap.

Check with other mariners in your area. Some paints work better than others in certain geographic areas. I use Interlux Micron CSC in Delaware with great results.

Our project has a 1983 17' that has never had a bottom coat. This boat has been in the water for at least 9 months a year for the last 20 years. Most years we use it for 9 months and then store it on the beach (below high tide so it floats periodically). We move between fresh and salt water all the time and it is stored in fresh water. We finally pulled it to town this year for much needed repairs and found about a dozen small barnacles, a thin slime coat, and 15-20 blisters smaller than a dime.
We are just about done fixing her with some new glass and gel coat and she will be good for another few years.
