Keel Bolt Replacement
If your keel bolts have deteriorated to the point where they are unsafe, or have failed entirely, we can replace them. MarsKeel™ can offer you replacement technology and techniques that return your keel to new condition.
MarsKeel™ has the ability to replace damaged keel bolts in the original keel. Our technology allows us to remove damaged keel bolts from keels and install new bolts with no loss in the surface shape, strength or position relative to any untouched bolt.
The benefits of this process over other methods are is it stronger then simply threading in lag screws through the sump into the lead. With our system you do not run the risk of hitting the old bolt with the new fastener. Our method does, however require that the boat is hauled the keel be removed.
We can offer you any bolt material. Generally speaking in most production boats that would be 304 or 316L grade Stainless Steel.
The bolt replacement process goes through these general steps:
The entire keel is coated with the required number of coats of Interprotect 2000E.
Once the keel has had all the necessary bolts replaced it is brought to the packaging department where it is skidded for shipping. If it is possible we will skid the keel up-right, to make installing it easier for the customer.
- Keel bolt replacement, removing and replacing corroded or damaged bolts with new Stainless Steel threaded rods in the original casting and original position.
- Keel straightening, we offer the pressing of damaged, bent and twisted keels back to as near original condition as possible.
- Draft reductions, we offer the use of our split torpedo bulb for yachts up to 40-45’, above that length a custom bulb and design and engineering services would be required for any draft reduction.
- Stability bulbs, an increase in ultimate stability can be achieved using our split torpedo bulbs up to a maximum total weight of approx. 3,400 lbs. Above that weight engineering and design services should be used.
