Topic : Weighty Matters

Anybody got any good tips on how to weigh an MR hull. Balancing on the bathroom scales seems good but how do you see what the reading is? (not to mention the difficulty of getting the boat through the bathroom door!). I also thought about taking it to a public weigh-bridge but don't know how accurate they can be, as they are designed to weigh lorries and stuff.

In the 60's Colin Stokes and Robin Fowler used to use bathroom scales and weigh each end being carefull to maintain the balance point at each end and sum the two = the weight. Personally I had a butchers steel yard and hung it off the garage door. These days measurers have load CELLS AND ARE USUALLY GENEROUS WITH THE LOAN THEREOF!

Using two scales you have to be very exact at keeping the boat level.
With one bathroom scales you can use a mirror on a long stick to read it. Find the balance point around the CB case, then sneak a peek. It worked on a Cadet, but might be tricky on a Merlin...

The New Zealand R class guys have no problem with this one. Look at the photo at the bottom of the page.

The Merlin version would be two people and two scales. Each holds bow or stern and steps onto the scales. Then weigh the people without the boat and do a little maths.

Thanks to ChairmanGGGGGG and to bob2926. I am in Yorkshire and the boat is not yet ready but it's great to know people are so willing to help. I'll probably make a further call when I get the new decks on. Thanks to the other respondants too; all good ideas are welcome!
