Hi Wouter,
"That is some wind you guys got there. A little bit to much 27-30 knots (force 7) is sailing in survival mode on any catamaran."
This is what makes the Mozzie a special boat in Cape Town - small rig with forgiving bows makes it possible to still sail in these conditions, even with the kite up (as long as you are willing to swim !)Actually we found it quite manageable, and push the spinnaker to higher wind limits with surprising results. The only reason I pitchpoled is the short steep waves that develop on the Bay, and I flew over the top of one into the back of the next one at twice the speed of the waves. The Hobies have long since packed up & gone to the bar in these conditions. This is not to say it`s always like this, but when the South-Easter comes through it blows this hard for 3 days in a row. If you have organised a regatta over that time, you have to sail in what you get, or cancel the regatta. As you can see, we held the whole 6 race series of our National champs in one day,when the wind "dropped" to 20 knots in the morning, but we ended up sailing in 27 in the last race anyway, which is better than having to re-schedule the event.
"but are not buying into the spinnaker concept since we often sail in strong winds and the Hobies fall over without spinnakers.You really mean "without" or should that have read "with". So what are the wind conditions where the H16's sail."
No, I meant they already fall over WITHOUT spinnakers, so are hesitant to add them. Ask any Hobie sailor if he needs a spinnaker in 20 knots plus, and he will look at you like you`ve just escaped from a high-security mental institution. They have a lot of sail area to deal with already, and, unlike more refined rig designs, cannot do much to flatten the main & twist the top off, other than add more mast-rake which makes their main even fuller. They are great boats, but find their limits sooner than we do - more sail area & less forgiving hull shape.
Wind conditions in False Bay from September to March are ideal for sailing - just a glimpse of this week`s forecast here - Thursday : S 20knots, Friday : SE 15knots, Sat : SE 10knots, Sun : W 15knots, Mon : W 20knots, Tues : SW 15knots. Hobies will sail in probably up to 22-25knots (but won`t hoist a spinn !!

) A lot also depends on sea state. False Bay can get a bit nasty in a South-Easter since it`s an on-shore wind, making big surf & launching on a beat difficult. Bring a spare mast & rudders

.
In December, bring a small windsurfer with 3,9sqm sail (smaller than your jib) - it often blows 30-40 knots for 3 or 4 days at a time, with a few days rest before the next big one.
"I just hope the Dart 18 try is out first. I did hear the Dart 18 was not really suited to the spi package but then again this could just be a rumour that was spread by a malicious opponent of the spi packages."
I believe they are not wrong - I owned a Dart and never admired it`s steering, the long narrow deep V-shaped hulls act as tram-lines and prevent rapid bear-aways which are so necessary with kite up. But there are Dart sailors here willing to try it, so we will see how they go.
Remember, your winter storage is our summer sailing, so there are always F16`s sailing somewhere !!
Cheers
Steve
