As you're planning to repair sails you'll need a zig-zag machine. I think the easiest to get hold of are the old all-steel ones made by Brother (often badged as Jones) and Janome (usually badged as New Home). The old one with a side-loading bobbin are probably the best to get. If you're sitting in front of the machine the bobbin access plate will be to the left of the needle. The old Jamome/New Home machines were mostly 500 series such as 515, 525, 535, 537. I don't know muc about the Brother model numbers from that era.
Some of the old Husqvarnas have an extra gearing in them which both slows down the feed rate and increases the power. Sorry I don't know the model numbers.
As for repairing the corners, mainly the head and clew, it should be possible with a domestic machine on the main of yacht in the low 20s LOA, which is probably going to be made from 5oz cloth. A Sailrite (not a clone!) will probably handle a bit heavier sail. Once you get up into the 40 foot yachts (not uncommon on this forum) you need a really heavy duty industrial machine built specifically for sailmaking. Then you get into the machines with pneumatically-driven needles...
Outside of the high-load areas, a domestic machine is probably going to be OK even on a large sail as long as you're not going through more than three or four layers. The challenge will always be to get the bulk of the sail though the machine's throat but where there's a will there's a way.
Thread size can be an issue. V69 should be OK in a domestic machine (use an 18/110 needle). It might take V92 but you'd need to try it. Larger needles (19s or 20s) are available for domestic machines but you'll have to search for them.
Hope this helps.
