Bottom Paint

Found a slightly used 190 that has bottom paint as it was planned for ocean use. The dealer tells me that paint is a good idea even for fresh water (where I'll be using it) if it's kept in the water for the season. Sounds right, but in reading other classifieds I've seen some that state 'never bottom painted' as if this is a positive selling point. Are there negatives to bottom paint? Anything I should ask about regarding it?


Thanks

Re: Bottom Paint

Welcome to iboats!

Well the downside to bottom paint is it has to been re-done again and again. Each time it is painted it should be prepped.

Just as a suggestion and I know others will chime in...... I would ask if they would remove it but, that is me. I do not really have any use for bottom paint in fresh water. In fresh water you MUST still keep it clean.

I had gotten a boat many years ago that was used only in fresh water. The bottom was black and I thought it was paint....... it was grime!

Where would be the best place to purchase this bottom paint? And, what preparations need to be done?

Re: Bottom Paint

Thanks, Bob_VT, for your insights. I didn't even think about having to repaint it. I was also thinking that it would keep the bottom cleaner, but it makes sense that dirt and grime will stick to the paint as well as the gel coat. It's been available for a while now and I was wondering if the bottom paint could be the reason.

Re: Bottom Paint

bottom paint isn't necessarily a bad thing, it's pretty common here with slip kept boats, but like these guys have said, it'll have to be redone every so often because once it's on it's hard to completely remove it.

Salt water and in a slip I fully agree. Fresh water is another story.

Soda blasting has become pretty popular and it is effective for removing paint.

Re: Bottom Paint

Here on the Chesapeake a virgin hull is a positive selling point. It indicates that the boat did not live in the water. It was either kept on a lift or trailered.

Re: Bottom Paint

No bottom paint is a positive slling point. It's only needed if you keep your boat in salt water. We've never had problems with keeping the family boat in fresh water all summer. Minimal gunk on the bottom when we pull it. I got my own boat last summer and it is painted. I wish it wasn't. I boat mostly in a brackish river, if I go up river it's fresh after a whiel. I trailer my boat so I'd rather not have the extra drag and IMO ugly look of bottom paint. Plus it needs to be repainted every couple seasons depdning on time in the water. Bottom paint, once on, is a pain to completely remove and keep your gel nice.

Re: Bottom Paint

I usually trailer my boat however this summer I will be able to keep it in water for extended periods of time. Unfortunately, I will have to pull it out occasionally...

Boat will be in brackish water so I plan to paint. I went through the iboats store to read up and I believe the Micron CSC will work, but if I am off or there is an alternative I am open to check into it before I get done prep work.

Also, the blue water paint site has this formula for gallon coverage, in case anyone is interested:

To figure out the amount of paint required: Length x Beam x .85 x 2 (2 coats)= Total / 300 feet = Gallonage Required

So my 21' w/ 7'9" beam will need approx a gallon and a half if my math is right. Do you guys recommend a prime coat or with a 3 coat application, can I get by doing that?

Re: Bottom Paint

I have been slipping my boat in fresh water now for 7 years and this will be my 8th. I do have bottom paint and wouldn't do without it. Where I boat, the zebra muscles have been very active. The bottom paint keeps them off. My biggest thing I like is being able to take a pressure washer at the end of the season and blast off what little gunk there is. It comes clean easy, however as they say, you sometimes have to repaint. I just prep n paint the areas that got blasted off. Its in the water all season long and nobody except the fish sees the patched spots. :D

Re: Bottom Paint

Bottom paint is toxic. That is why it is able to do what it does (keeps critters and growth off the bottom). If you don't have issues in your area, I would remove it rather than let the toxins wear off in the water. I have 3 boats, two of which are kept on lifts so I guess they don't count, but the third (26' pontoon) sits in the water all season. I've never had any issues with growth or 'critters'. Just my 2 cents.
