[sees photos] I think I give that two years before it starts to look dated - if it doesn't already.

Unless you make the old boats obsolete, nobody is going to rush to buy a new one.

Not I should point out do I have the remotest interest in this boat, it's just as usual my three happorth, my pal has one, think he might jump if it had something 'special' going on.

Are they not boats that male/female teams like to  use, another reason for it to be lighter.



But if you DO make old boats obsolete, why bother to buy a new one? Without strong and equal fleets, and a strong PY, why buy a new RS400 rather than a different boat (unless you are one of those strange people who like a gear advantage in a class where they aren't supposed to exist?).

As others have said, much of the point of sailing a SMOD is the fact that they are (or should be) all equally fast.  Take away that, and you lose most of the point of sailing a SMOD.

Changing stick-ons or things that don't affect boatspeed in normal conditions is one thing; changing basic hullspeed is, IMHO, another.  And we had an interesting experience in the Tasars before the hull weight was brought in, when some boats were about 61kg.  I did three races on my brother's 73.5kg boat.  In a 76 boat national title fleet, including world champs in 'Balls and Tasars, we lead around the top mark twice and were about 5th at the bottom mark each time.  We climbed back to third by the finish, but the thing that really struck me was that the lighter boats gained about 50-100 metres down the reaches. That WAS enough to be totally dispiriting if you were the one dropping from first, but it was NOT enough to be really noticeable to the crew without another boat to pace against.

It illustrated to me that if you drop the weight, you can tear apart a boat (as a top-line racing machine) without improving the perception of speed, either from aboard or ashore.  The Tasars brought in a minimum weight and the issue of uneven boatspeed just about vanished. 

Personally, I think that supporting a class rule that destroys the competitive and resale value of another person's boat is something akin to robbery.  They purchased an object that had certain values (in this case, competitive performance) and it's hard to morally justify someone else taking that value away.

Some changes can of course be made, like consumables. Or you could compensate older boats in some other ways, by relaxing some other rules for old boats.

Whether SMODs HAVE to upgrade major non-consumables to stay alive seems unproven.  The Laser hull has basically not changed and it's not exactly a dead class in most places in the world.  Squibs, Fireflies and other strict ODs don't seem to change hulls a lot and seem to do pretty damn well.

Isn't it natural for a one design class to evolve over time?  The key is not to immediately create a split in the class - I think the class needs time to decide if these changes would result in this.

Perhaps some of the the emotion is coming from the fact that a profit making company is involved and people get cynical about their motives.  Which I suppose is understandable, however I'm sure I'd care about profits if I was in their situation!

Without evolution Lark sailors would have no spinnaker and GP sailors would have wooden masts, small jibs, no spinnaker and sink every time they capsize!  Smile

BTW I think a 17 year old RS400 looks less "dated" than a 17 year old Merlin Rocket, Cherub or Moth.  Tongue

Surely changing it to a square top main, without changing the mast or the sail area, is going to give heavier crews an advantage as there will be more area high up, so more heeling force.
Plus, unless im missing something obvious, wouldnt a square cut main have a shorter foot than a pin head main of the same area? Therefore wont the CoE be moved forwards, giving lee helm?

There is no Forum as such.
Just a Yahoo group which has had a small number of postings.
Generally against change.

I would have thought that the new sailplan will change the balance of the boat, the mast and spreader setup and rake sttings, and will almost certainly provide a performance increase downwind, and probably upwind also.  The carbon bowsprit SHOULD be lighter, hence reducing the pitching moment, and should also be stiffer, hence reducing panting resulting in a more stable kite shape, which will improve performance in a chop and in heavy winds.
The carbon boom SHOULD be lighter and stiffer, and not only will it reduce the sailing weight, but it will also reduce the moving weight offwind.
My money i on the change to vinylester resulting in a stiffer boat too.

Having recently bought a 'mid-range' second hand 400 at around the £3k mark the prospect of splashing out half the boat's value again to be able to compete at opens does not appeal.
I quite simply cannot believe any claims that these changes won't make a difference to speed around the race track. Arguments that it makes the boat more 'user friendly' are just a thin cover for faster through manouvers (hoists / drops), so.... faster round the track.

New sails - about the only bit that I would go along with - you expect to buy new sails if you want to keep a boat competitive. Only those that have recently got new rags loose too much. I was considering new sails - think I'll hold off for a bit......

Kite system - if they can make a retrofittable system that workes like the 800 then great. However isn't the biggest problem that the 'ole in the front is too small?

Carbon pole / boom - why?? Ok slightly lighter, but how would a carbon pole be smoother?

New resin for hulls - again whats the point - my old boat in the mid 500's was still stiff and light despite being 15 years old.

Main / kite sizes - the boat is very nicely balanced as both a w/l and round the can machine. Why make it only able to do w/l?

Feels like it.
Not so much financially, I've had pretty good VFM over 4 years, but the loss of excellent level racing.
 
The trouble is, what alternative class is there?
If they did this to the Enterprise, you could get an Albacore or something
If it was the Laser 3000, you could move to 29ers or RS500's or...
There is no substitute for racing the RS400, at least around here!

Am I the only one who thinks that the existing 400 rig is excellent as it stands? To my mind it just looks 'right'. The proposed new sail plan and material make a proper racing craft look like a throwaway beach toy.
 
I'm on the outside of the class looking in, but potentially someone thinking of moving into the class next year. This move would put me off as if I were to buy second-hand I would have to add 1500 quid to the purchase price before going racing. Or would second-hand values fall initially to reflect the outdated nature of the kit I'd be buying...?
