Potential issues with encapsulated keels?

I keep reading that encapsulated keel designs are safer. Sure, they don't fell off capsizing the boat in the middle of the ocean leaving the crew little chance to escape.

What can go still wrong? Is rusting a real threat if the core is iron?

Re: Potential issues with encapsulated keels?

Like anything they're a trade off. Well built encapsulated keel that is properly maintained will outlive the rest of the boat. Downside? Encapsulated keels tend to have been built at an era or price point where the idea of replacing a diesel or water tank">fresh water tank was never considered and your tank corrodes and leaks into your fiberglass/keel.

Also tend to require more weight to have the same righting moment.

Re: Potential issues with encapsulated keels?

"It depends" I prefer encapsulated keels. But they need to be sealed up well so no water gets in. As such, iron or whatever is used as ballast wont rust and be good for a lifetime.
-If any water gets in and your boat is stored on the hard for the winter somewhere cold, the water can freeze and create a bulge in the fiberglass keel.
-Encapsulated keels tend to have thicker cross section, so a bit more drag.

Re: Potential issues with encapsulated keels?

I love my encapsulated keel with lead and racers love their bolt on keels.
Here is a very good write-up, about pros and cons.

Re: Potential issues with encapsulated keels?

If you talk to yard workers they will tell you horror stories of working on encapsulated keels, particularly if they are iron. That's not a comment on their inherent strengths or benefits, just issues with respect to repair and maintenance.

Honestly, on well built, well maintained boats you hear about keels falling off as often as you hear about people being struck by lightning twice. It does not happen that often.

Re: Potential issues with encapsulated keels?

Thanks for the feedback! Taking good care of the tanks is a good advice.

Suijin: right, I'll try to find one with lead inside, at least rusting shouldn't be an issue...
