Subject: hull flexing and backstay
Info: (12715 views) Posted: Saturday 7-3-10 07:09:02 AM
So I had several people look at it, and give me the thumbs up. No delam, just very subtle flexing of a mm or 2. Something to watch, may be an issue in 20 years. I may change the attachment system at some point, or reinforce it.

:: It doesn't sound good to me. It would be interesting to
:: hear from others who have their backstay rigged this
:: way. On Moxie, we have ours completely external and the
:: backstay attaches below the scuppers on the transom.
:: Sounds like this is a much more secure location as it is
:: at a hull joint where there is a lot of support and
:: structure. We have had our backstay rigged like this for
:: many years and I like it a lot.

:: :: :: ::
:: :: :: :: Here's what me and JP noticed while fixing our backstay
:: :: :: :: system. Our backstay, like most of the boats I think,
:: :: :: :: has 2 main attachments: 1 is the deck hull joint just
:: :: :: :: port of the tiller; the 2nd is on the floor of the boat,
:: :: :: :: where there are 2 little fiberglass bulkheads just to
:: :: :: :: starboard of the exiting scupper where the floor meets
:: :: :: :: the transom. There are little chainplates on each of the
:: :: :: :: little bulkheads. The starboard line of the backstay
:: :: :: :: divides and one end attaches to one chainplate and the
:: :: :: :: other end goes through a block attached to the other
:: :: :: :: chainplate and starts the fine tuning system. After we
:: :: :: :: fixed everything, one of us was below looking at the
:: :: :: :: attachments on the little bulkheads, while the other one
:: :: :: :: hauled on the backstay from up above. When the backstay
:: :: :: :: is on, the floor of the boat lifts!! And when you pull
:: :: :: :: it on and off, the floor just goes up and down. Yikes!
:: :: :: :: Does this happen on anyone else's boat? Is this ok?
:: :: :: :: Thanks!
