Re: Tell Me About Jeanneaus
Another aspect is the strength required by the relatively short chord/expanded bulb type keels.. I don't think lead alone would be strong enough to prevent the bulb from eventually bending the keel.
A steel internal structure or an iron 'fin' with a lead bulb seems to be the practice there.
We've owned 3 iron keeled boats and 2 lead keels.. the first two had never been properly sealed and the keels were a mess until we did so. Our current boat has iron, well sealed and faired and it's been fine.
Given the choice I'd probably still go for lead, but today the market is full of iron keels so you might be severely limiting your options if that's a 'deal breaker' for you.
