43' and about 18,000 lbs with a tiller since the 90s, with a rtw via cape of good hope, still cruising, still winning regattas....in their 70s! To my knowledge they are 2/26 S43s with a tiller.
Their blog is amazing, imho, because it's real sailing and I believe it to be the oldest blog around, pretty inspiring too

I have wondered if they being tiller steered has helped them to keep cruising all these years but that's because theirs is very racy, all flush, no cockpit coamings, lots of
deck aft so they can sit there with their feet up to steer. A lot if back and leg degeneration can build up standing over a wheel for long hours, bulkhead mounted with a cushy powerboat captains chair (think
catamaran or mono like Amel Maramu) I think mitigate this problem with the aging sailor.
My S43 is the most customized around. Wheel of course but I've a hard
bimini arch and its positioned just right where I suspend a hammock chair and can steer floating just aft of the wheel, using the stern seat as a foot hold if need be. Otherwise SV Wings tiller setup would be nice.
