V8 force 9

Having fun on a lake

Pretty small waves for force 9 , Beaufort scale is not based on windspeed alone ....spam blocker wouldn't let me cut and paste a picture and description of force 9 , might I suggest looking it up in "American Practical Navigator"....

It was force 9 and over, waves look small indeed, partly because of the Go pro effect, partly because the lake is not that big. The north sea on that day, was totally out of control, therefore the choice was safety

Force 9 is wind of 80km/h+ with gust of 120...

your hat was barely moving and the SUP guy was standing up and seems quite ok.

haha,

my hat is a neoprene cap and very tight.

Yes he's experienced in downwind, although this was the max.

We had quit a bit of damage that day in the Netherlands and the wind tipped my trailer over with the ski and sup.

btw, I know it's wind over 80 km/h , thanks

OK there is a lot of angst on this forum at the moment and I just want to add my bit.
Wind speed is measured in Knots. Not kmh or mph. Knots.
Boats speed is measured in Kilometres per hour, kph. Not mph. and
boats are measured in metres. ie 6.2 metres. and centimetres ie 43 cm wide.
Come on people, get with the program.
There I've said it. Now I'll sit back and wait for the storm.

I'm sorry my mistake then, in Holland it's measured in the beaufort scale, so that's the 9, that's about 80 km/h wind with stronger gusts.
That would be 40 knots I think

Hey Flowmaster, I believe you! You're barely having to paddle.
The camera really does have a tendency to flatten things out.
And I've paddled upwind in 40-50 knots and kept my cap on

Flowmaster , please pick up a dictionary...Beaufort Scale is a measure of sea state (which includes wind AND sea surface i.e. wave height ) . Glad you stayed on the Lake with the intrepid SUP'er , The force 9 out on the ocean that day might of been a bit much.

Dicko, your right about wind speed, but, internationally boat speed is measured in Knots or nautical miles per hour to correlate with minutes of latitude on a nautical chart. IE; one minute of latitude equals one nautical mile. Ocean currents are also measured in knots.
Being a licensed charter boat Captain I have always found it interesting how ocean paddelcraft race courses are always measured in statute miles or kilometers. Always seemed silly to me.

Force 9 equals a "Strong Gale" with winds 41-47 knots.
Equivalent to 75-87 KM/H or 47-54 MPH.

AND , by definition includes a potential maximum wave height of 40 ft. determined by duration of blow and fetch. ( for force 9 , 25 hours of blow with unlimited fetch produces 90% max. wave height . From "American Practical Navigator" , Bowditch , Vol. 1 Table w2. A gust of 47-54 does not by definition equate to Force 9 , it's about how long the wind blows over how much distance of water surface at what speed....

In Hawaii, we almost always referred to wind in MPH (miles per hour) and there was always a good sense of what to be expected. Basically, it worked.

Speed also given in MPH, while Length was given in feet, and width in inches.

I prefer: MPH for wind speed, kilometers per hour for boat speed, meters for length, and centimeters for width.
I probably have confused the heck out of all of you… but I am still laughing because it's all so true.

Fath2O, I understand the correlation between nautical miles, latitude etc, but paddling at 8 kts isn't as impressive as paddling at 12 kmh. This isn't charter boat.info, it is surfski.info and the international surfski.info standard unit of measurement is kph for speed. We use knots for wind cos it makes us sound knowledgeable, we use kph for speed cos it makes us sound fast and me use the metric system for boat measurement cos everyone except the USA uses it.

Dicko, Your the one who said "BOAT" speed is measured in KM/H on "Surfski.info" - not me!
And yes KM/H always sounds more impressive than knots.

I use MPH for wind speed and boat speed, Feet and inches for boat length, and inches for width.
degrees Celsius is jibberish to me. 50c sounds nice to me =(

Remind me again why the hell we didn't change to the metric system years ago...? I can do imprecise conversion in my head, but when I want to know if a ski listed in metric is 17.5" or 18.4", I have to go to google.

LOL about the metric system in the states. We all lost on that vote.
At $0.43 a liter for fuel, people felt pretty good… until they realized that it was more than $1.50 a gallon.
You should have heard the people in Hawaii, CA etc… complaining to high heavens. It was comical.

… and that's how the liter went away, quietly - alongside with all other metric measurements in the USA.

$1.50/gallong gas doesnt sound too bad now! Im only 30 years old and dont remember the Metric push at all, but isnt it time to start another one?

In the short term it will suck, but I am an engineer and converting everything to or from metric is a pain. Im sure millions of hours are wasted every year converting things...

Totally off-topic, but anyway.
Unit conversion losses might be larger than hours only. This is a famous example:

I suppose I'm one of the rare fans of the English/SAE/Imperial system of units (preferably breaking inch measurements down to decimal equivalents), though as an engineer I do work in both metric and English on a regular basis. Much of it is probably because I have 55 years of knowing the system, giving me a feeling for the units (while I still don't have a feel for most metric measurements other than mm, cm, meter, and liter), but I also find it convenient: a foot is, well, roughly the length of your foot. An inch is roughly the distance between the joints in your fingers. It's roughly a foot and a half (a "cubit") from your elbow to your fingertips. And a yard is roughly the distance from the your fingertips to the center of your body along your outstretched arm. It's simple to apply for a distance estimate. And naturally, car engines should always be rated in hp and cubic inches: A 392 Hemi sounds much more impressive than a 6.4L Hemi!
