I sailed VERY little boomless. I would say just try it and see. Just make sure you are close hauled and sheeted in tight with good speed as you start the tack. Use the roll tack technique. If you don't know it, get "Catamaran racing for the 90's" off www.catsailor.com
online store. It is a great book also for all around sailing and will teach you more than you could learn in three years on your own. There is also a chapter by Carlton Tucker on the Hobie 17.
Get the book, it is worth the $30. I have passed it on to 12 year old grand daughter I am training now.
