BC 23 Waterline length?
« on: 18 Aug 2022, 18:36 »
Does anyone know the waterline length of the BC23?  Not the overall length!

I need it for an RYA YTC rating certificate for next week’s Dartmouth regatta Dayboat class.

Does anyone already have an RYA YTC certificate for their BC 23?
Thanks
Mark

I have the LWL as 6.5 metres. We work on a performance based handicap or class handicap in Australia.
I would be interested in knowing the RYA rating.

Lara at Swallow has confirmed the waterline length for the BC 23 as 6.53m.

RYA has used 6.58m (perhaps misreading my .53 for .58)
Using that figure,  the RYA YTC has rated us at 987 with all four sails, and 1012 with “white sails”.

This does not include water ballast.  I asked for two ratings, one with and one without water ballast, saying I would commit to with or without ballast at the beginning of a race series or regatta.
They refused saying it is their policy to rate all water ballasted boats without the ballast, as they cannot control whether we pump it out or move it. Clearly people cheat to win!

I will let you know how we seem to perform against other Dayboats with this rating in the Dartmouth Regatta this next weekend.

At least getting your LWL figure as less than your LOA figure has increased your SWYTC handicap number (improved it) from your original 982!
 ;D

That said, that 987 YTC number will still make life tough for you in a mixed fleet, imho.

SWYTC, especially with the RYA interpretation of "displacement", does throw up some "anomalies"...

Have a look the mini transat style, rather sporty "Django 7.70", a 25ft bilge keeler, with inboard diesel saildrive. 40m2 upwind sail, 92 m2 downwind with large assim. But displacement 2600kg.
RYA YTC rated 993/1024, ie "slower" than a BC23...

I did quite fancy one of these, but Mrs SS thinks it "looks like a spaceship"...

There's water ballast and there's water ballast...bilge keelers and bilge keelers?  :-\
