Hello.I've bought some thicker (4mm vs the original 3mm thick) chainplates to reinforce the originals that transfer the load from the forestay to the foredeck fitting.I intend to fit the new plates in parallel with the existing ones.(Also bought some 10mm dia 35mm length clevis pins.)I obviously need to slack off the forestay enough to allow the pins to be pulled & the new plates fitted.I did a trial run last weekend and fitted a 4-1 purchase onto the fork of the backstay so that I could ease the backstay safely.Also slackened off aft and centre shrouds.Finally ran the main halyard to the foredeck and used mast winch to tension.Despite all this, due to the weight of the forestay and foil it was difficult to reattach the lower end of the chainplates to the foredeck fitting due to the sag in the forestay/foil.I had no way (that I could think of) to get a purchase onto the "eye" of the forestay.Should I just have eased off the backstay more?Any suggestions welcome.ThanksJohn V 1447 Breakaway
Re-secure forestay chainplates to foredeck fitting?
- Thread starter Vega1447
- Start date
Any suggestions?Essentially I'm asking whether there is any negative in allowing the mast to rake as far forward as necessary (using a temporary purchase instead of the backstay) to allow the forestay clevis pins to be pulled?And whether there is any trick (a tall helper with a boathook?) for mitigatigating the sag in the forestay when re-pinning the forestay chainplates to the foredeck fitting?Steve B?Thanks,John V1447 Breakaway
Hi John
I have the same problem every year. How far short
is the forestay from connecting? Perhaps connect forestay first as you can
get more purchase on the backstay. Have you changed anything in the
rigging?
You can always add a toggle to the forestay. When
tuned the mast should never have any forward lean. Slight aft lean is accepted
as perfect.
So long as you have enough ropes, halyards etc
holding the mast so it can fall forward then you shouldnt have a
problem.

Thanks Steve.
That all makes sense.
I'm probably overcautious, comes from being a mathematician not an engineer..

Have you considered releasing the tension on aft lowers also? WaltTo: AlbinVega@yahoogroups.comFrom: AlbinVega@yahoogroups.comDate: Tue, 24 May 2016 17:56:22 +0000Subject: Re: [AlbinVega] Re: Re-secure forestay chainplates to foredeck fitting?

I keep my lowers a little loose but they are marked so If I want to
race I can tighten to the mark; I think this keeps the deck from
sagging under the mast and I can't tell any difference in the way
she sails. Vega was designed as a wooden boat and that was the
practice back when she was designed. We kept the lowers loose on all
wooden boats except when racing. Doug

Hello Steve & all.
I did the job last weekend - it took a lot of time easing all the
shrouds, fitting 7-1 (3-1 plus main sheet 4-1) purchasefrom
backstay fork back to cockpit winch to allow me to release the
backstay from fitting at aft quarter and refit once job done.
(In fact I just released one of the backstay terminals as that
allowed the mast rake forward enough to free the forestay from
foredeck fittings.)
I've fitted new chain plates in parallel (almost) with existing
ones.
See
side.jpg
and
front.jpg
The new plates are 4mm thick, the old are 3mm thick.
I planned to install the new plates exactly in parallel with the old
but had trouble getting the new chain plates to exactly line up with
the old despite carefully specifying the dimensions of the new
plates.
I'll re-align (making small adjustments, filing/drilling where
necessary) over ther winter when I lift out.
Is there any issue with the new setup?
Thanks,
John V1447 Breakaway
