What happens if you just ignore a rusty keel

If you have an iron keel that has a tendency to rust what happens if every year you just chip off the loose stuff. Wire brush what you can and bottom paint.
It will get worse and worse of course but what it the worst that will happen?
It will look nasty.
It will not be smooth so will slow the boat down a 10th of a knot.

I don't think you will loose enough iron in 10 years to cause any ballast issues.
The keel is not going to fall off.

Can you think of any other down side to ignoring the rough keel.

Re: What happens if you just ignore a rusty keel

Be honest that's my plan too..

Clean it brush it and paint it do touch ups as neccessary..

A. I'm in fresh water
B. I'm on a trailer so minimal "soaking" time
C. I can do touchups week to week or a slightly larger job once a year ( I store boat at home)
D. The whole sand blast, epoxy prime and glass an 1/8" thick seems like overkill for my needs.
E. I don't believe it's gonna go all to hell in 5-6 months...

Re: What happens if you just ignore a rusty keel

It does mean the same routine on every haulout whereas if you spend one haulout getting it properly treated and sealed that's the last time for awhile.

But essentially if you're prepared to do that work each year (and don't leave it for several seasons undone) then you'll suffer the loss of speed and the OMG looks each time you lift it!

Personally (as one with an iron keel) I prefer the sealed approach and the minimal work each year (and the option to get two seasons out of a bottom job).

At about 250 for paint two season from a bottom job has some merit.

It will continue to rust and get scabbier and lumpier.

It will slow you down a lot more than 1/10th.

It will require a lot of nasty work every year just to keep it in SOME kind of shape.

It very well MIGHT fall off - see the attached pic of what was somehow holding my iron keel on when I bought the boat.

I included a pic of what I replaced it with.

Re: What happens if you just ignore a rusty keel

I'm wondering if the rust could work its way back and into where the bolts are........causing a much worst issue than doing it right sooner than later.....

I had to redo about 4 yrs ago the iron keel I had, Pulled out a year ago after 3.5 yrs in the water, only needed some caulking at the keel/hull joint, and repaint. Should be good for another 20-25 yrs if the original epoxy covering went that long.
