Silly question time - can someone please explain to me what is meant by "long boarding"?

The term was used in regards a survey I had done on my recent purchase:

“long boarding after filling” – can anyone please explain what this means? All I seem to be able to come up with (when googled etc) is about skateboards - and I am pretty sure that this is NOT what the surveyor was refering to:D

Thanks
Paul

It is a technique used to fair a hull. You take a long wooden board, maybe 3 to 4 foot long, often with foam on one side, and fix sandpaper too it, you then work your way along the hull sanding at about 45 degrees to the axis of the board, and working your way through finer grades of sandpaper as the hull gets smoother. If you actually intend to do it let me know & I'll post a fuller description. I should also say to attach handles to both ends of the board

Back breaking work, so usually only something racers do.

Sounds like the survey has shown up an uneven hull, so the surveyor is suggesting you use filler to build up the surface in the depressions then longboard it to get a fair hull.

As dt4134 writes. Also commonly used after gel-stripping when filling and fairing prior to application of epoxy barrier coat. One would typically rub the surface with pencil, then long-board: where the pencil marks remain are low spots requiring further filling. Then more long-boarding...

I assure you, Peejaysea, that this is all you want to know about it. Back-breaking work.

Back breaking work,

What he said and the back breaking bit is very true! ;)

As has been explained, it's truly awful. I'm surprised Oldsaltoz hasn't been along - he's the sort of masochist that gets off on this kind of torture! Having tried it, I can safely say I'd rather be water-boarded! It's the only real way to fair a surface with compound curvature though. If you use a small rubing block (or worse still, your hand) you'll find that you get a smooth surface but it will be full of hollows in places where you had to rub a bit deeper to get a blemish out. The trick is to hold an illuminates strip fluorescent light up to the finished hull and look at its reflection afterwards. On a nicely long-boarded hull, the reflection of the light in the hull will be a smooth, uniform curve, not a load of ripples. Alternatively, just look for the skipper who looks like he could carry a double decker bus under one arm!

I did something similar when restoring an old car, I used very cheap spray paint primer to lightly mist/speckle the surface then sanded. The high points sand away leaving speckling in the low points.
