You can get a H18 performance manual part number 613, and cost only $19.00. The catamaran tuning guide will help as well, part number 607 and $29.95. Any one of the Rick white sailing video's will help make what your read clear. They are listed on page 46 of the Hobie catalog and are al $29.95. We usually have one playing in the shop and I learn something new each time! I hope this helps let me know if you have any other questions!
Thanks,
