Weighing a boat

[westernsailor]

I am looking to get a boat weighed for handicap purposes.

Any interesting experiences.

You need a crane wih a certified load cell. Boat is normally cleaned out of absolutely everything - and that usually means bunk cushions the lot, (unless its a one design where the cushions ar specified as 'in' and if that were the case why are you weighing the boat as there is invariably an accepted 'class weight'?)

So with the engine running on fumes, and with everything off, you get the boat lifted and you get a weight. Of course some boats dry sail - to avoid the weight take up of water in the hull, to ensure a smoother bottom because those sorts of boats have crews to polish them as well. So if you are really keen you can dry the boat out a bit first before weighing it.

If you are anywhere near Gosport Boat Yard, they have an aproved load cell and will do it a lot cheaper than most places. No RORC measurer necessary. Know exactly how much fuel you have on board, no water and imagine what would fall out if you turned the boat upside down, if it falls out it must be taken out. Allow at least one man day to empty the boat, bloody exhausting. Then think safe storage, a transit van or similar......best of luck

Uh - not bunk cushions. Scatter cushions yes, bunk cushions no. Also all fenders, warps, sheets (but not halyards), anchors, cables, engine spares, water diesel, buckets, sails. In fact everything not fixed. Having done it, I promise it is a drag. The new boat will be weighed BEFORE we put any gear aboard.

The RORC rent loadcells, or will weigh the boat for you for £6.50/metre - this time round I'm going to get the boat professionally measured (endorsed certificate) so that we don lay ourselves open to any rating protest - the % error allowed is VERY small.

My previous boat was an X99, and they are weighed at national and international class events. They are picked up by a single line attached to a keel bolt which runs through a special purpose hole in the coach roof. To be acceptable, not only must they be within a tight weight tolerance, but the line must not touch the sides of the hole either, to prevent abnormal trim giving an unfair advantage.

Whoops - sorry - both the last two boats we raced specified bunk cushions in as part of the once design rules and I assumed that other deisgns weighed with them out. My wrong assumption - apologies.

Is that a one-design boat that was made once upon a time, but not any more (like Extraverts)? If it isn't, I think it should be.
