Title: weight
Post by: philipcosson on 01 Jun 2006, 06:50
Hi,

How does one weigh a national 12?

There is a spring balance at our club (but I wonder when it was last checked against some accurate measuring device)

I would like to measure the weight of my hull BEFORE i make any changes to see what needs doing to get it down to weight.

I have looked for public weighbridges - but not found a local one yet.

regards.

a good set of bathroom scales, weigh the front with the very (i.e. riiight at the back) transom perched on something - then turn the boat around and do the same in reverse. add the two together.

should give you a pretty good ballpark weight without summoning a measurer!

Philip,

The man who might know when our scales were last calibrated is Keith Whitfield - a measurer for the gp 14'sand a member at SDSC,  or try Judy Armstrong or Andy Young. Sam will be able to put you in touch.

However I like Mikes idea - seems very simple & sensible and likely to be as accurate as the scales/

A good place to start with weight loss is the boom - unmeasured weight - as well as helm and crew!

I'm sure more ideas will come to light

How did you get on at Northampton?
