In "Plunder", I think? The bad old days, certainly. ;-)

True -- but if this triangulation technique were readily possible, making such charts would become both more easier and more accurate.

Indeed, there's something rather reductionistically Malkioni about the whole method.

That's a mental picture I'm happier with myself too. But bear in mind that they didn't have the _option_ of long-range triangulation in the RW (until the longitude problem was solved). If tin compasses and accurate bearings on the RM are possible in Vithela, it's hard for me to entirely preclude the possibility.
