Bought boat and sailed couple of times but now taking a closer look I see hair line cracks in the hull were the 3 chain plates are on each side. has any one seen this on there lancer, and how to deal with this?
Sounds like quite a job. Sorry to say, but I just wished you hadn't used 5200. 5200 is a structural adhesive and lacks the flexibility to be a good sealant around the chain plates. It is also hell to remove later. It was a great idea to leave them exposed so you can keep track of them. Were the chain plates themselves in good shape?I did my chainplates last week. I wish to heck I had taken photos for you all though but I was a man on a mission at the time and didn't stop to snap a few. The fiberglass covering my chainplates belowdecks had spiraled from weeping water to seaping water to dripping water. So time to do something about it. I removed the fiberglass the way any Marine would: a chisel and a rubber mallet. I then repaired the few knicks in the fiberglass of the deck and cleaned the chainplates (the nuts were loose enough on the bolts that I could handturn them after just a few go-rounds with a ratchet). I resealed ever possible seam topside and belowdecks around the chainplate with 5200, put a bead of 5200 around the inner and outer perimeters of each chainplate and reattached all of the hardware connections. I left mine exposed to the cabin air instead of glassing over them again because I didn't see the engineering value in it. The job seems rather solid and no water has permeated the area of the chainplates after two days of rain and a 3 gallon bucket of water test.
