Here's a hull speed story some of you racers might find interesting.
My current boat is a centerboard Bristol 30, a 1960s CCA racer designed by
Halsey Herreshoff with full keel, cutaway forefoot, attached rudder, etc.
Of course, IOR boats like C&Cs sail circles around it in lighter winds. In
12-15 knots, it will sometimes reach 6.6 knots. But, in more than 20 knots of
wind, with full main and a 130, the boat will hit a steady 7.5 knots on a close
reach with jumps up to 7.8 knots.
This is GPS speed in Boca Ciega Bay just off Tampa Bay, a protected area where
you can have 1-2 foot seas and little current when the wind is really kicking
up, which makes it fun to sail.
The waterline is being stretched out as the boat heels over 30 to 40 degrees,
but that shouldn't account for all the speed. Especially because I am not a
racer.
I guess the Herreshoffs knew a thing or two about designing sailboats back in
the day.

Well I wasn't peed off, just skeptical of those speeds based on my own mediocre
experience but kudos to you Sam for doing what one famous America's Cup skipper
referred to as "No Excuse to Lose"...keep up the good sailing and no need to
keep quiet from my point of view; I have never seen knot abbreviated as kn,
that confused me in conjunction with the numbers so I asked; perhaps I am the
one who should have kept quiet

A few things :
My genoa is an almost new laminate sail; The main is only 5 short seasons old;
I've got a folding propeller ; my bottom is smooth like a babies - I take it
out every winter!; I’m measuring speed with a Speed Puck (GPS)
The 8kn readings were brief and fleeting (not more than the 10secs to register
in the instrument. The 7kn readings did register though, but they were not
sustained - like the 6+kn readings were. During this whole time I was beating,
which is why I pondered on the possibility of sustaining 7 or 8 on a beam reach.
I fairly regularly exceed theoretical hull speed - If you're not, you're not
trying ! The 26 is not known to be a fast boat. I've done a lot to get her
faster. There are a lot of faster C&C's on the water which is why the 26's
aren't raced.
And yes the 27 is faster!
Sorry I pissed so many people off - I'll keep quiet in future!

sorry Russ, I thought he said a beam reach must have missed the part about
puffs, still that's very fast for a 26 but if he can do it course be damned as
you say, then good for him

Hi Dwight,
Please reread Sam's message before getting out the pitchforks. He said 7 or 8,
in the puffs. I would not characterize puffs as "regular"...
On a prairie lake I think his experience is quite achievable in hot summer
conditions when all you want to do is sail fast, course be damned.
Cheers, Russ

what do you mean by 7kn to 8kn regularly?
If you mean 7 knots or 8 knots through the water or over the ground with a C&C
26 I would say you should be a race winner every time on corrected time; that
is really fast for a C&C 26 even on a beam reach and I got a feeling you would
probably leave my 35 MKII struggling to stay close behind...before everyone
runs out to get a C&C 26 are you sure about those numbers; I have only ever
seen a couple of C&C 26's around here...I don't remember them being quite that
slippery, in fact my C&C 27 MKIII always seemed to be much faster on all points
of sail

I know there’s a few 26 owners on here so thought I’d share my thoughts on
optimizing my sail plan.
Jump in anyone, I’m open to any thoughts!
Â
Was out sailing today, only boat on the lake – I love that! So I thought we’d
play around with the saill plan.
Wind was 8kn -12kn. (Estimate – I usually think if I ssee the occasional
whitecap it’s around 10kn)
Â
I have a 135% laminate genoa from Evolution Sails in Toronto (2 seasons). A
Dacron main with 2 full and 2 partial battens from Leiche & McBride in
Vancouver (5 seasons).
Â
I have a flexofold prop; 4-1 outhaul; Garhauer genoa cars; Harken traveller;
Cunningham; Garhauer ridged vang; (no backstay adjuster)
Â
The C&C 26 is a tender boat and we were doing about 5.5kn to 6kn beating to
windward at 20deg – 25deg heel. Flattening with the outhaul reduced heel a bit.
(speed measured with a Speed Puck)
Furled the genoa to about 110%. Just brought the leech forward of the spreaders
so no interference.
Boat stood up to 13deg to 16deg. Speed was between 5.8kn – 6.4kn. Went up to
7kn or 8kn in the puffs (theoretical hulll speed is 6.25kn) No bubble in the
luff of the main.
Obviously, the furled genoa wasn’t setting great and the starboard tack was
better than port tack. On a beam reach I think she’d do 7kn or 8kn regularly.
Â
So here’s my thoughts:
I’m thinking of getting the genoa recut to a 110% or if that’s not
practical (...and I suspect it isn’t) order a new 110%.
Eventually a new laminate main will be needed too!
I’m well pleased with 6+kns at 10kn of wind and 16deg angle of heel. Very
little weather helm
I’ve not tried it yet with the genoa at 110% in light wind. In heavy air the
main can still be reefed (...as could the 110%).
Â
OK guys, am I missing something?
(I’m not looking for advice on where to buy used sails!)
