back  to the original  question 

make sure you set the boat up well  for the conditions and   don't hold back at the start, its better to be near the front rather than ducking around  slower boats. Rs 400's  use to be absouletly pigs to pass.  As for the rest of the thread well nothing beats water line lenght in light winds,  but then in those  conditions  playing the gusts or shifts   right tend to be far  more important  than whatever  the boat.   If you read  bethwaite  then from his reasoning the  cherub should be  equal upwind  scp  is equal   but I think  Paul Biekers  thinking about  upwind sailing is  far more important and that  high performance dinghies atre in the semi forced stage  most of the time up wind  in a breeze  ( sorry cherubs but  equivalent waterline lenght   still plays )    ie  you've no chance against   14's 49ers etc upwind.  Downwind  its adiffernet ball game as  its down to  drag  and since the  cherub has ee haw  in its  back  end compared to  some of the others then  game on.  the late  great Dave Ov said  that the 29er was  one of the fastest boats that  he sailed downwind because he cold drive it hard in a big breeze and not pitchpole. 

from a personnal viewpoint  look at the scottish skiff  travellers  the spread is from 4000's and cherubs which took a handicap  drop to qualify to 18 ft skiffs its interesting how  high performance classes do.  the  mps dominates  due to numbers but also  th top 3 sailors in the world  also do the events. In sub 15  knots it was  how  sailed  not the handicap  that  mattered  ie  a well sailed 4  tonner  would  beat  a  49er  around the course ! 

hANDICAPS  ARE  ARE  AN AVERAGE OF CLUB  RETURNS IF YOU DON'T  LIKE THEM  MAKE SURE THAT YOUR CLUB DOES THE RETURNS.  THEY CAN WORK WITH THE NUMBERS THEY GET !

ICs are not that great in the very light. You've got small sails and, because the hull is so very long, quite a lot of wetted area - much the same as a Cherub for instance. But as soon as you do get a bit of speed and form drag comes into play, well, suddenly its another game entirely.

i reckon a well sailed IC mut be pretty good in very little wind. easily driven hull, efficient rig.

A well sailed 4k can beat a 49er in a drifter!

Whereas a well sailed 5k will beat almost everything in a drifter!!

49er 531 & 5000 5025 and a mirror(now gone to mirror heaven)!

4k will beat a fair few cherubs on the water, even the odd 05 rules one.
 

Not sure about that when it's honking Fergus.   



When its honking probably not, but VERY close the rest of the time, downwind the cherubs pull away, but upwind 29er/4k etc will catch up a hell of lot.

anyway.....
 

 

Well yeah they will because he Cherub is shorter and twin wire!  It would probably give they 14 a kicking in drfiting stuff

Somehow i don't think a cherub can give a 14 a kicking in the light stuff. 14 have the extra waterline length plus much bigger sails

 

I was talking about the 4000 u fool lol!!!

To answer this question perhaps one should read and reference High Performance Sailing by Frank Bethwaite. It makes my brain ache everytime I try to go through it but I'm convinced one of these days I'll get it!
