Beneteau with Iron keels have easily replaceable keel bolts, that's the information I was looking for. Thanks. Any others?
Here is the thing, with boats there are no silver bullets or always true statements. Like most things about boats every decision is a compromise.
Not all Beneteaus have iron keels
Not all Beneteaus with iron keels have easily replaceable keel bolts.
Iron keels typically come with some mix of less stability, poorer motion comfort and/or poorer sailing performance.
Not all lead keels have J-Bolts
Not all boats with lead Keels and J-bolts have keel bolts that are hard to replace. (You drill new holes and nut pockets just the way lead keels were built before J-bolts were invented, and if you go back with Monel nuts and bolts you will never have to replace them again)
Boats with iron keels that may have steel keel bolts that may be easier and cheaper to replace, typically need their keel
bolts replaced on a more frequent basis (10-to 15 years) vs lead keels with stainless steel bolts(25 to 40 years)
Boats with lead keels and monel keel bolts, pretty much never need their keel bolts replaced.
