8/22/21 M17 Recommendation shoal keel repair attn: Dave Scobie
Dave, Last November, I had a tree crash through my fence and boat shed. My M17 saved the ground from being damaged. After removing the debris it appeared the only damage was to the starboard mooring cleat. Unfortunately, today as I began my list of items to restore my M17, I found the exterior starboard centerboard shoal keel was cracked from the tree fall damage. The previous owners had taken good care of the boat and the shoal keel was not cracked. I suspect the force of the tree impacting the starboard stern mooring cleat raised the boat bow up and gravity slammed it back down upon the trailer. Do you have any references of how I should proceed? I did quite a bit of epoxy repair to my former harpoon 5.2. I am looking forward to venturing into polyester fiberglass with gel coat finish. I could not attain a painted finish as good as the gel coat. However, as this is the underside, I am leaning toward rebuilding the surface with epoxy? Additionally, re: the stop pin. As I do not intent to race but cruise, do you recommend faring in the stop pin or leaving a proud external stop pin (reference friends early 70's M17). As I am in the Puget Sound region, I expect I will have to pull and recoat the centerboard every 5 years. It just seems an accessible stop pin would be beneficial.

Ouch! Sorry for your misfortune, and the labor that you have in front of you.

Tim. I'll do some thinking on how I would approach and respond. The list members will also comment and the community brain trust will also provide you with many approaches to make repairs. :: Dave Scobie :: M6'8" #650 :: SV SWALLOW - sv-swallow.com :: former owner M17 #375 SWEET PEA - m17-375.com :: former owner M15 #288 SCRED - m15namedscred.wordpress.com <<-- new site!

Tim Drill a 1/4 inch hole on the very bottom of your keel and see if any water comes out. I can see RUST inside that crack which indicates water. Water freezes and expands and cracks the keel. This happened on Miss T a 17 owned by John Edwards and that crack is the same. John actually bought Tom Buzzi’s 17 recently as a replacement. I don’t see how a tree would crack your hull from the inside out like that. I hope I’am wrong Bob [cid:5B798252-10FD-498F-9FC5-2EC532883BAC] Sent from my iPad On Aug 23, 2021, at 6:49 AM, tdelacy@wavecable.com wrote: Dave, Last November, I had a tree crash through my fence and boat shed.

I tend to agree with Bob that your crack was not caused by the falling tree. In addition to freezing water, the other thing that could cause that crack is rusting steel, which expands as it oxidizes. You will need to decide whether just to fair it and fill it or do a deep dive and replace the steel with lead. -----Original Message----- From: Bob Eeg <montgomeryboats@hotmail.com> Sent: Monday, August 23, 2021 11:03 AM To: For and about Montgomery Sailboats <montgomery_boats@mailman.xmission.com> Subject: M_Boats: Re: 8/22/21 M17 Recommendation shoal keel repair attn: Dave Scobie Tim Drill a 1/4 inch hole on the very bottom of your keel and see if any water comes out.

Thank you for all your comments. I'll execute the drill option, recommended by Mr. Eeg. I'll provide feedback. When I decide on the repair, I'll try to document all my steps. Would be nice to add a recipe for recovery to the collection of M15 and 17 repairs.
