Maybe you washed yours in cold water and it shrunk?

Doh!

This might help (from Peterman's site)

* Estimation of the volume of a board (empiric made - don't look for any logic):*

1. Measure the board where thickest.

2. Measure the circumference of the board with intervals of 20 cm (starting 10 cm from the stern).

3. The measured circumferences of the board are put into the formula: Circumference/221*20*thickness/13, which of course is calculated.

4. The sum of the results (from "3.") tells the volume of the board in liters.

Peterman provides a spreadsheet of some boards he measured, compared to the volumes quoted by the board maker (can't reproduce the spreadsheet here) but the figure for the Bics are pretty good: Bic say that for a 282, the volume was 107 L (108 L calculated) and for the 279, the quoted volume was 96 L (97 L calculated). For the 299, the quoted volume was 149 L (153 calculated).

Hope this doesn't hinder you!

Hi, Thommo,

After you have done the calculations, please let us know what the result is.

Thanks.

You could measure the volume by submersing it in a tank (or a wheelie bin).

You'd have to take the bin to the beach and live with the shame of washing your bin in the sea... whilst looking pretty weird

So 1 litre will support 1 kg! I have friends with pools so I can do that. I also like the idea of putting it in tank and measuring the displacement. That said, I can't for the life of me think of how I will do it, i.e. where the heck I can get a tank that size.

Thank you everyone for your help. From what Larko has told me, I do feel reasonably comfortable that the board is 94 litres - ta.

I hear you. It's difficult to compare oranges to apples but my 94 litre AHD seems to have alot less bouyoncy than my old Mistral flow 93 litre (bump and jump) and current Fantatic Freewave 95 litre...perhaps like the stated length, nothing's quite what it's meant to be
