    Also, safety factors are usually used to make the cable the weakest link: a lot "better" to break a cable and possibly dismast, than breaking open one third of the deck

    You would definitely have a problem connecting new 8mm wire terminals to 6mm mast tangs and chainplates too.
    Bigger wire, bigger eye and pin sizes .

    Larger size clevis pins may not fit in the holes.I would change like for like if that was the original spec.

    A previous owner "cleverly" changed the shrouds on my boat to 8mm instead of 6mm.
    I suspect because he was able to get some cheap, rather than for any performance or engineering reason. He didn't bother changing the forestay or backstay, they're still 6mm!
    It's a pain in the transom! I had to buy a very expensive rig tension gauge (>8mm = twice the price for the gauge), tuning guides aren't written for non-standard rigging, in fact this winter I'm going to swap it back to 6mm.

    The Westerly 31 and the majority of other boats have low tension rig; no need to increase the wire diameter; even if you were to replace the 6 mm with 5mm or even 4mm (hypothetically) it would make no difference.
