single suit of sails.
TO me that means you cannot change your sail configuration between races. IE one dayers or two dayers. Start with spin end with spin.
If I were you, I would just rig and then choose to use it or not. Its too much of a pain to rig and de rig it. This way if the wind settles down to a more manageable speed for you, then you have it.
Its better to have it and not need it, than need it and not have it.
I think
in theory you could be forced to sail with all sails on board that you started the regatta with.
When you get to the windward mark, you can CHOOSE to hoist the Spi or not.
When sailing when it's very windy I have at times not hoisted ont Kite on the last lap as the rish / return was too high. Classic example was the last race of the First day of the Mumbles event last year. I was exhausted and Running second and decided that I might catch David who was in front, but there was a greater risk of me washing the sails.
If the boat behind me was in danger of catching e, I may have put the Spi up.
