Year Name Length Beam Hold Lasts Factor for lasts 1590 Vergulde Leeuw 90ft 23/24ft 10ft 75 lasts 276/288 1592 Tonijn 94ft 26ft 13ft 100/120 lasts 264/318 1592 Dolphijn 100ft 26.5ft 13.5/11.5ft 100/140 lasts 218/256/305/358 1593 Neptunus 102ft 33ft 13.5ft 250 lasts 181 1593 Valk 90ft 29ft 12ft 80 lasts 350 1598 Tijger 90ft 25ft 12ft 80 lasts 338 1601 Zilver Ster 104ft 25ft 10ft 130 lasts 200Where I see factors that are too large, I suspect that the lasts are wrong. Factors such as 200 or 218 are reasonable. 338, 350, or 358 are not. If I were calculating, based on dimensions, I would say that the last factors should be as follows:
1590 Vergulde Leeuw 90ft 23/24ft 10ft 95/100 lasts 1592 Tonijn 94ft 26ft 13ft 150 lasts 1592 Dolphijn 100ft 26.5ft 13.5/11.5ft 160/140 lasts 1593 Neptunus 102ft 33ft 13.5ft 200 lasts 1593 Valk 90ft 29ft 12ft 140 lasts 1598 Tijger 90ft 25ft 12ft 120 lasts 1601 Zilver Ster 104ft 25ft 10ft 120 lastsWhere I see great deviations, I suspect that either there is at least one bad dimension, or that the last figure is faulty. The factor can fluctuate between 200 and 240, but outside that range either says that one of the factors that I mention is at work, or else the ship's form is very extreme. Lasts are a measure of volume, and the factor is trying to describe the form versus the box made by the length x beam x depth in hold. Sources:
