Chris: You want one of these - https://www.harken.com/productdetail.aspx?id=5749&taxid=375 Or - https://www.harken.com/productdetail.aspx?id=5269&taxid=375 The difference between the above are the height/lift of the arm. Get one that closely matches the current one on your M15. Choose a block of the same size as the one that broke to attach to the arm assembly. NOTE: confirm you need a new arm as you may be able to attach a replacement block to the existing arm. If still unsure share a picture of the current fitting (reduce image to under 300k or the email server will not forward the image). :: Dave Scobie :: M6'8" #650 :: SV SWALLOW - sv-swallow.com :: former owner M17 #375 SWEET PEA - m17-375.com :: former owner M15 #288 SCRED - www.freewebs.com/m15-named-scred/ On Fri, Oct 11, 2019, 2:11 PM Chris Smith <chris.r.smith@gmail.com> wrote:
Hello fellow sailors!
I have an older m15 that needs a new mainsheet block. The current one attaches to the step in front of the cabin (as most do) but the bearing housing has split. I epoxied it back together but it has started to split again. It still works, but it sure makes me nervous in a blow.
Any suggestions for a new one?
Many thanks for your collective expertise!
Chris
