paddy pikes the man for that

Girth x girth x length divide by 800.

Thanks Hurricane. The reason i ask is that if you look at my thumbnail pic, it looks much much bigger than
24 1/2lb. Thats what my mate said it weighed but i didnt see the scales at the time. Stubbo is convinced it may be a Thirty or there abouts and its got me wondering now !

You will never know for sure I"m afraid mate but if you have accurate measurements it may give you a better idea.

I didnt take any measurements at the time. Trusted my mate to weigh it and never really thought too much about the size until tonight when i started to get comments on the size of the thing !!

what scales were used mate? if it was those avons with the different coloured indicator for each time the dial goes round he may well have misread it.

Ive just checked my Avon scales and the 24 1/2lb bit is in the reddish zone, but if you go round another revolution its still in the reddish zone but thas indicating 32 1/2 lb !!!!!!!!!!!

I dont know what to think really, all i know is that it was HUGE in the boat and felt very heavy !!

I KNEW IT!
The avons are notorious for it...especially if you don't use them a lot (as in having a mate read the weight for you)

God , i,m like a small child with excitement ! Its sounding more like it is a Thirty !

I will have a word with my mate in a couple of days and take my scales and show him. See what he thinks. It was a few years ago i caught it and im 100% sure we weighed it on avons !!
