Hi Peter,
After I sent the initial message, I found a conversion table on the net,
which calculated that 48.6 mph to 72.2 kph. While no where near the speed
record, it's still scootin' for such a small cart. Believe me. If I

thought

I had gone 107 kph, I probably would have parked it right there. And

again,

that figure was obtained from my GPS. I don't know if vehicles in NZ have
both miles and kilometers on your speedometers, you will see that 63 mph

is

100 kph, which will give you some comparison. I plan to be at Ivanpah in
2006 also, so hope to see you there...lee

All going well, I hope to make Ivanpah in 2006. Unfortunately, the 2005

meet

falls too close to other planned events to attend.

I am mainly sailing on firm but wet sand which probably offers greater
rolling resistance than your dry lake bed. My kart certainly creaks and
flexes at speed and is occasionally airborne too. More frequently the
windward wheel loses contact with the ground.

According to my conversion, 48.6mph equates to 107.63 kph, which exceeds

the

world record...not that I disbelieve you for a moment. lol!

Hi Peter,
My top speed, that I have recorded with the GPS, is 48.6 mph. Offhand,

I

don't know the kph conversion, but that was enough to get me across

the

dry

lake in a hurry. The other side of the lake was coming up fast, and

was

not

quite sure if I could turn in time,but I did. At that speed, this

light

little cart sure skips around a lot, like it's only hitting the ground

every

few feet?. And I just LOVE IT!!!! Hope to see you at Ivanpah. Lee

OK Lee.

I admit I'm not quite that heavy and have a lower centre of gravity,

(lol!)

but suffer much the same problem. I too have a 4 metre sail and have

been

blown right over on more than 1 occasion when standing still!

Obviously

the

force of the wind sideways is greater than the force required to

overcome

the inertia needed to get you moving forward. Once moving however,

the

4

metre sail seems quite capable of handling wind speeds up to around

40

kph

or higher. My GPS has often recorded speeds in the mid to high 50's,

but

I

have yet to break the 60kph barrier. I've never used a 3 metre sail

so

don't

know what difference if any it would make.

Hi all,
Regarding the 4M sails, I thought I'd drop a note. I am a big

guy,

weighing 270 lbs and over 6 feet. The 4M sail helps a lot,

especially

in

light winds. But I do note a control issue with higher winds.
Before winter hit, I was sailing in mild winds with the 4M

sails,

which

increased to 30+ mph winds rapidly as a storm approached. The GPS

hit

48.2

MPH at one point, my second highest speed noted. Before I could

get

back

to

the truck to change to a 3M sail I suddenly had a gust of

considerably

over

30+ mph. That gust caused my cart to slide approximately 20 to 30

feet

SIDEWAYS, then continued in my original direction as if nothing

had

happened. Pucker factor:10+. Changed sails to 3M and had a ball.

Is that why your so quick Ben, Did you get a Big 4m?
I haven't noticed that much variation, but I haven't laid them

together

maybe, PB or the sailmaker at blokart, could clear up how accurate

the

cut

would be. I asumed it would be to a pattern possibly CNC cut in

batches.

Hi Kem,
Its hard to have an argument for keeping to blokart sails, as

the

cut

in

the sails that come from blokart are different in cut shape, as I

have

seen

in my 4mt with other 4mts, so why not get a sail cut by another

sail

loft

so

long as its within size, as blokart cannot supply all sails the

same.

See ya

G'day Jimi,
Thanks for the constructive comment. I just thought it was

worth

raising

for disscussion, as most guy's here run pre stretched rope as it

saves

the

gloves and reduces the burn in 50kt gybes. I don't think that's a

problem,

but I can see where it could go and I want to keep it simple.

Your right about the grease, I reckon that it doesn't make

heaps

of

difference, but the ceramic bearings I refer to, have less rolling
resistance at 10times the cost, I say stick with std.

With the Pod's I've swapped mine over with someone of

resonable

sailing

abitity in a naked blokart and won. As well as chased a mate at

70km/h

last

weekend, he was naked and I had the Pod on but still had to work

my

lines

to

catch him, I couldn't just cruise up to him.

Enjoy!
Cheers
Kem

Greetings Kem,
Just having organized the 2004 Japan Championships without

finals

due

to

lack of wind, I see where you're coming from.
2004 Japan Finals due this coming weekend if winds hold up.
Back to your items in- and outside the race:
Should we race under the blokart rules or water sailing

rules?

– I like the blokart ones.
= I say blokart rules, absolutely.
Mainsheet ropes – Is an aftermarket pre-stretched type

accepted?

– I don't mind the standard but find the prestrectch

smoother

and

faster

reacting.
= If pre-streched or a RED sheet has your fancy, Go for

whichever

or

RED.

Sails – Should you be able to get your own cut, as long as

it's

within

size?

– Rigid wings would be fast:) but I like the blokart sails a

good

combination between being rigid/fast and flexi/stretch to

soften

the

gusts.

= I don't want to go there;
Masts – full carbon one piece?
– I like the pull apart, packability.
= Let's stick to the blokart issue and have budget decide

CRB

or

not.

On the

day there can be absolutely ZERO advantage to CRB's as I see

it.

5

kilos

difference will do much more.
Bearings – Ceramic or standard?
– I don't want to go down the costly ceramic slide.
= Bearings are a matter of choice I reckon. To what degree

do

we

want

to

discriminate the various types of grease used in standard

bearings.

Utterly

impossible.
Tyres – Aftermarket with size or tread variations?
– I like the Std tyres.
= Let's stick to standard.
Cleats – Adding cleats and locking attachments?
– This is an unfair advantage in marathons, as it takes some

work

away

from

the pilot.
= Out with the lazy-aids is my view;
Airfoils – Mudgaurds or side wings?
– Do we allow them in racing?
= Out, is my view;
One more:
POD or DirtSkirt?
– I used a POD in the 2004 Japan Race for simple promotion

purposes

and also

because it is the First Prize. Regardless on a good wind day

I

would

have

removed it.
Best regards and H.N.Y.
Jimi

Hi All,
Just a disscussion, on what your opinion is on

modifications.

This

is

for

blokart racers who compete in these wicked, one make, racing

machines.

To

give a bit of perspective, I will list a few mod's and we

can

hopefully get

an agreement on what is acceptable.
So the fastest sailor wins, not the one with the biggest

wallet.

(It

maybe a

bit of wallet envy)
I just want to make clear that these are not my ideas, just

my

opinions. I'm

raising the discussion to get scrutineering events,

standarised

internationally if possible.
Should we race under the blokart rules or water sailing

rules?

accepted?

Where would you like the line drawn?
