What is the most money you have spent in 11 minutes?

Ignoring houses, flats and cars. Which leaves shares. 

I suppose £20k on my ISA on April 6th annually. Is more investing than spending though?

I put £26k on my Amex at once for my wedding, so that probably is it though it was multiple things for the wedding to one vendor.

Spending is probably a trip, I'm sure I've hit 5 figure credit card charges on luxury travel in one go, but I don't think I've gotten up to the wedding amount - maybe £13-17k and usually spread over flights, hotel, etc

So it's planes and boats - all agreed 

Investing isn't spending. Otherwise buying my equity stake would have been the most....but I need that to generate the money to buy my boat 

Which was 293 thousand dollars plus tax
