Re: Keel Bolts

I am missing something...you either have a centerboard that pivots and raises and lowers inside the trunk....or you have a keel...

The centerboard is most often secured to the boat, usually by a pivot pin or large bolt through the trunk.

the keel trunk (may have some weight which adds to the total ballast weight, or not) which I think you are talking about having several bolts that run through the bottom of boat, likely has the bolt through the floor and through the trunk and may have nuts on the bottom of the trunk on those long throughbolts. Some manufactures do run the bolts down into the keel or trunk and they have enough thread capture to meet the design requirements without nuts(think huge lag bolt). Some are adhesive attached in addition to these bolts.

More info or photos, please.
