Hi All,
I am beginner with tight budget. Bought my board without information.
Really want to know the litres.
How can I get by dimensions please?
Because I found myself easy to lost balance on the board compared with my last board, the bigger one. The bigger one does not have litre as well.

Thanks!

It's not easy, by dimensions, unless you have a laser scanner and a computer to help you.

You can divide the board up into rectangular bits and add them together, to get a rough idea.
Easiest way if you don't have a big enough tank to use the displacement method, is to see how much weight it takes to sink it.

Sinking way calculation, kg=litre?

Kg=litre is correct, just remember to include the weight of the board. But you don't really need to do the calculation because the only reason you'd want to know the volume is to know how much weight takes to sink it!

As a rough estimate you can compare the board with another of similar dimensions. Typical old-school waveboards - 60cm wide, 28-30cm one foot off - will be 75-85 litre.

If you're prepared to do a bit of work.
Divide the board into 10cm sections, take the thickness and width at each point which will give you the average thick and width for each section. Add them all together and multiply by 0.848 = volume.
Used many times and It's accurate.
I just measured a Patrik Formula 200 and I got 199.7 litres.

I have been using SHAPE3D LITE software to find the volume on my board before I start on a new one.
The 3d lite is free.

Isn't that a Bic Veloce 120?

Looks a lot like the Vivace 290 to me but you could be right. Vivace 290 was 120 litre, I think only 58 wide, fast as hell, crummy to jibe, trim box fins, very durable skin. I had one and replaced it with a much more versatile Protech 285 CAT.

Vivace was the race version. I had 3 of them thru 10 years, the 270.
Veloce was the tuned down rec rider freeride board.
Well, I found the EnergyXR a smooth jibing board that excelled in planing jibes.
A hard jibing board would be the speed trial boards which range in width from 15"-17.5" for me. Those you had to keep speed and look for flat water.

That is definitely not a beginners board, its an old school free ride / slalom board.

Its only got 120 litre of volume, if you are a beginner you'll need around 150 litre and it should be at least 70cm wide to be stable, preferably with a centre fin or a dagger board.

That's at least 35 liters bigger than my board 10 days after my initial 2 day windsurf lesson.
85 liter was uphaulable for a 150 lbs person.

and just to nit pick, it's probably 120mm thick not 12mm.

Bic Veloce 120 litre is what it is.
I've still got one in the Olskool retro collection. For a lightweight beginner it could be done. Long nose compared to new gear, but still a relatively easy n fast board to ride.

Looks to me like a veloce 278.
Get hold hold of a ruler. If it's 278cm long and 57cm wide it's 101 litres.

Hi Madge, I always try to fit the board ; not board fits me, because the budget. Hopefully get use to it soon.
Thanks.

Its hard to sail for intermediates...

Sorry I know you're on a budget but even 30yrs ago when that board was made, beginner boards were much larger.

If going really crazy cheap old stuff, you need a cheap boord 3.5m long and 70cm+ wide

In newer stuff - even 10-15yrs old - it will be the same length as that blue thing (or less) and about 80-90cm wide.

Look at pics of a Starboard Go 150 to 180L and you will see what you need (ideally)
Then look at pics of a Windsurfer One Design from the 1980's and there is your cheap option.

Sorry but that you have is demoralising for a beginner.

You said this is easy to lose balancer on - yes!!! You need width to be stable.
You would be better off on a old old Formula board that is fragile, than this narrow experts only board.

Thank you much. What's your weight? I tried to learn on narrow 110L 282 and it was quite challenging. I went to 150L and it was super easy plus I could keep the board for light wind.

What's your weight? 120L could work if you're persistent and lighter!

Problem is that it will set you back with progression as its narrow and has limited buoyancy.
Start on something much wider until you can at least move along and tack etc.

Will continue my try for the 120 L one.

My last one is , I guess 150 L, it takes lots of worry when I carry it to the beach, my soft /mobile roof rack can not fix it very well. Also It is heavy, compared with 120L board, because I load the car using one hand to hold the board.Lastly, I found it is hard to run smaller sized board when I get used to 150 L board. I don't have lots of time, I need training hard to get there.
Thanks for advice!

I am 79 kg.

The basic principle of volume is that every Litre holds 1 kg, nut you must also take into account your rig weight etc too.

So you are 79 + rig 11kg, thats 90 litres used, some times its also plus board weight. 10kg, so thats 100litres used, so you only have 20 litres spare.

Usually a beginner should have at least 50 litres spare.

The big board although cumbersome to get to the beach is way better for you but give the other one a go and see what happens.

Hi Madge and all,
Today I had the third trial of the board at relatively quiet condition, felt wonderful, fast. I will keep training myself. So far I can't manage the direction, I wanted to go one line, but always lost.
One of guy he play foil, we met there for 3times, he said my board is Veloce. From Latin, means fast. I searched, it is Italian, meams fast, rapid.
