Ok...

If Hobie would decide to do a "Sport Getaway" and add a boom, I bet it would be a loose-foot, like a H17SE. It will require a different completely sail and maybe a taller mast.

New Sail: $750-1000
Hobie Boom Kit: $500-700 (we know how Hobie loves to over price "Hobie" brand stuff).
Possible new mast: $$$????

So you are looking at a $1200-1700 upgrade atleast. I don't know if it would be worth the price? I am a big fan of the Getaway and this year we will have 5 Getaways in our fleet so there will be a racing class for them.

All the Getaway sailors I talk to like it boomless and would rather have a larger foresail to fly on light wind days.
