looks to me as though forward pressure on the spreader cracked it and only then would a halyard have enough force to pull it forward like that.  Do you use any asymmetrics? Maybe if so with a lose backstay or too little cap shroud tension you might be able to pull the spreader forward enough to crack it???

Just speculation I'm afraid

Jenesis, 
Wondering if you could share with us the ball park cost of the repair?  and does the mast need to come out for the repair to happen?  I have a 400e:2007 and there is a crack in one of the spreaders in line with the pin located away from the mast (the one on the right of your photo). 

Background: My rig was re-done 3 years ago.  The boat motored from Sydney to Melbourne, and was used lightly i.e. sails up maybe a dozen times since then.  I recently purchased the boat (and did not do a rig inspection...thinking nothing much would have happened in the last three years..doh!). I had a rigger go up to check the rigging (routine, no apparent issues) and found a crack in the spreader at the pin.

Asimo - just in case you don't get any local or more relevant reply, I had to replace all 4 spreaders and have mast-doublers fitted in Nov 2022.  Ex-VAT UK costs then for supply & fitting were:

Spreaders £1635
Doublers £1050
Sheaves £100

The cause was that the mast wall was not strong enough to take the compression loads, presumably compounded by cyclic loading.  The doublers are simply plates rivetted onto the mast to spread the loads around the spreaders.

Hope this may provide some sort of ball-park estimate for you.

Replacement spreader cost AU$706 including international freight, plus labour to obtain and install in place AU$1045. Plus freight from Sydney $35. This was in March 2022.

Interestingly this is now a problem (in a much greater scale!) with the Globe 5.80 transatlantic race. Hopefully I can post the speculation below 

Entrant UPDATE 1:2:2025...SPREADER CRACKS...in the past Globe 580 Transats, two 580's have experienced spreaders cracks...now RENAUD has discovered the same. Replacements have been organized from FRANCE Selden to ANTIGUA...all entrants with SELDEN masts have been advised to check their spreaders...the cause may be overloading from the spinnakers or pressure from the mainsail pushing the tip of the 29 degree swept back spreaders forward. clearly the forward tip of the spreader is point loading as it flexes forward. SELDEN use a short stainless steel internal extrusion inside the spreader going through the mast that incorporates the attachment of the lower shroud that is not associated with the spreader so there is no weakening of the rigging there. SELDEN masts are NOT compulsory. A Builder can make their own mast with a class approved section...or buy one from approved suppliers..SPARCRAFT supply 580 rigs as fitted on TREKKA , but costs nearly three times the price.

Latest post from Renaud : During regular boat inspection I discovered yesterday at the end of the day my split starboard arrow bar. That's a blow to the morale. Fortunately the alizés are not too strong and with the help of Ariane my boat manager and Don the replacement parts are on order. I don't really understand how this could have been done because we made mainly starboard amure. There have been a few shortcuts to the south but never quite strong. Finally we can all talk about it in Antigua. #mgr2025 #g580t #CG580
