2013 302 Windlass Model

[SeattleA28]

Hey 302 owners, Hoping someone can confirm which Maxwell windlass model came from the factory on 302s. I'm trying to confirm what chain and rope size is compatible. Looking at the Maxwell site, I assume Coablt used the Maxwell RC8 (5/16" chain) but it could also be the smaller RC6 (1/4" chain). Also, Maxwell calls for 8-plait rope, but I see many 3 strand ropes for sale that claim compatibility with Maxwell. Anyone have 3 strand?

Thanks in advance....
