Oh I don't know...I mean the title says "request white sail". As in one sail. Nobody mentioned any rigging, ropes, masts and stuff.
Maybe some more information on how exactly it's going to be used would be helpful? (how many sails, how many masts and ropes, to what ship they will need to attach later, is it for background use or for close up >>how detailled does it need to be, does the player need to be able to climb the masts, will it have to be one big model or some sort of modular set, etc, etc...)
Just, y' know, so interested modelers can estimate the time it would take them to create that.
