First, YES, the jib is worth it but only if have a custom one is made IMO. My Wave takes off just on the jib being sheeted only. I've made passes using a stopwatch with exact distance calculations and the Waves are quicker than you think. Especially with the jib. As a previous H16 owner and sailing solo almost always, I can't even begin to tell you how much I love the Wave. I made a custom over sized jib for mine. Roughly the same size as a Hobie jib but with a longer foot and leech. I also found that sheeting the jib to the sides of the tramp (where the factory jib kit does) doesn't work well. It will flap like crazy and drive you nuts when pointing. Basically useless when set up like that. I have mine sheeted just off center on the tramp. Points excellent, slot is much tighter and gets the sail flatter.
Some things to consider: The mast is VERY far forward on a Wave. In heavy air while running hard it will try to pitchpole. It's a super digger
. Basically becomes a submarine. Getting the maximum amount of mast rake makes all the difference on a Wave. I am installing an additional adjuster on the front and going to shorter custom length shrouds as well as installing a MS traveler and 4:1 Harken low profile MS blocks made for the Wave.
I only sail in big air (15-25 minimum) so having the traveler and being able to go block to block on the main w/maximum amount of mast rake will really light it up.
If you sail in light air all the time I would not do these mods.
pm me for more details if you'd like
This guy has about the best setup for sailing a Wave in big air (I think he's running 6:1 blocks on the Main which is overkill IMO):
