Waves and Getaways are not going to be anywhere near as fast as the fiberglass boats. The 16, 17, & 18 are all about the same speed around the race course if they're being sailed by equally skilled sailors.
Maybe have staggered starts where the Wave starts first, Getaway starts 5 minutes later, 16 and 17 start 10 minutes after the Getaway, 18 starts 1 minute after 16 & 17. Or set up a windward mark that is 50% to 75% closer to the start line for the rotomolded boats.
Of course the other option is to use the Portsmouth handicap system and record finish times for each boat and then calculate the handicap finish, but that's probably more complex than what you're looking for.
