Time for a spinnaker?

Until we cracked the rudder stock, we'd been cheerfully chugging downwind not really missing a spinnaker- it has a decent turn of speed, especially given the amount of weight it was shifting. Granted if the breeze had got up before we reached the end of the island the spinnaker boats would have left us standing.

Hi Al

Good to meet you briefly on Saturday ... and a pity you did not get to really experience Icon in decent breeze - it would have flown up the Swale where there was a lot more breeze later.  As for the spinnaker thing .... against 'real' asymetrics they will of course pull away but the 'lesser' ones will need to have ideal angles to keep pace with Icon.  We have raced against good Merlins that are more comparable and Icon offers roughly similar speed upwind, is significantly faster on fetches and reaching and on deep running when the MR's spinnaker is relatively most potent the better ones will creep away but Icon will hold onto the less well sailed ones. However overall the testing this Summer suggested that it is not as fast as a Merlin ... but they need to be very well sailed indeed to pullout any significant distance.

Might still make Icon the fastest 2 sail production boat though   ... anywhere !   

Next time then ....

Mike L.

The Icon is longer than either a Merlin or a 400 I believe?
It ought therefore to have good performance against these boats upwind.
I think that's why in some conditions we find Albacores hard to shake off until the kite goes up.
Fastest production 2 sail boat is a bit of a claim.
Are we talking PY or peak speed?
When you say boat do you mean kiteless hiking monohull dinghy?
Or does it really see off Tornados, MPS's, Canoes (if there is such a thing as a 'production' gnu?) etc.
I'm sure I've missed out some faster classes.

In my view, you should consider class rules that stop people using self-destruct rudders, unless you want people to have the expense of needing both fixed and lifting ones to be competitive.
When people buy a racing dinghy, they are not just buying a boat, they are buying into a class and that means the rules, ethos and constitution of the class have to be taken into consideration.

Icon is about 2 inches shorter than a 400, but probably 45kg lighter.

Certainly the fastest 2 sail 2 man monohull that I can think of. In fact, even if you add kites only the 400, Merlin, B14 and 59er are faster hikers.

WinkYeah i would think the Canoe might have a fair few things to say about that also doesn't the Musto, 700, Vortex have just two sails?
I know it was a bit tongue in cheek

Well, we were ahead of both canoes until we hit the bottom... But I don't think Mike was counting singlehanders or cats.

Good to meet you too Mike, it's a lovely little boat that you and Peaky have brought into the world

What is this obsession with speed.

In my life I've come to realise that the only people interested in speed are pre-teen boys and people with something to prove. 

Sure its a small part of it but the sailing experience has so many more important considerations than speed!

I'm not knocking the boat here just that if I was in the market for a new boat... I would want to know that I could punch through our tide... but after that speed would be of no interest to me.

A big claim !!

Well ...er yes.   Partly said to be provocative but the word 'production' was buried in there and I could further qualify with the term 'hiker' and 'monohull' but we did not try to make it 'fast' Icon just ended up that way...  It does not have a particularly high top speed to my mind relative to some out there but it is quick, and very much so on some angles.  To answer Ian - probably more than quick enough.  The hull is a very efficient low drag shape as is the rig and that allows us to leave out the spinnaker some might want (and the associated weight of all that gear)....  and we don't do hauling round great lumps of lead either !   

The design brief was for a light 'easy to sail' modern '2-sail' hiker that would go as well in the light stuff as in a blow and was accesible to more people and usable at more locations (OK OK maybe not Peaky's at low water round Sheppey !!)  We wanted to get more people out there and really enjoying their racing .. oh and it had to have a modern light rig and be at a reasonable price.  We also wanted a wide weight carrying capability.

Anyway the best thing about it is simply the Icon sailing experience and handling - oh off I go ... no I'm not going to go on and on about Icon now  - only 'you' could really judge for yourself.   I'm far too biased. 

Lastly - Peaky was involved with pre-production testing and we welcomed him trying out alternative rudder systems on his boat in the immediate time period.    Production boats have a fairly standard pivoting rudder ... and funnily enough it looks exactly like a Blaze one  - so no surprises there ....  ;-)
