I need advice on how to justify sail number 7.
I have 3 wave sails and 3 slalom sails - I am chasing the elusive big sail for the light wind days, been a lot of those here in Perth lately but on the bright side I have the kids to fight with over the Rudd bonus.
Trip away - new sail
Wii - new sail
etc

Jeez dude, sounds like what you need is a NEW SAIL!

Order it right now! What are the kids gonna do, go on strike??

Remind them who the sperm came from that made their very existence possible!

They OWE you, man!!

go for something like the KA. then you can have the holiday, play the Wii and get 2 sails.

Does it have to be a NEW sail Graceman?
Could always do both. Get a good nick 2nd hand sail (assuming you can find what you want) AND the other things.
Wifey will be sooo impressed with you she'll let you buy a new fin too.
