What about boats where the anchor lives in a slot cut through the bowsprit? You can only use one anchor, short of messing about to replace it without risk of dropping it in the deep while disconnecting. No second roller for an alternative anchor either. Why do mfrs do that? Sure it looks neat and tidy, but it`s silly. Riviera do it, others too. Makes no sense to me. Too limiting.
We like to lift our Super Sarca out of position and stand it nearby, on its end where it sits fine, to free up the bow roller when picking up a mooring ball so we get a nice straight pull on it, can`t do that if it`s in a slot.
Could bowsprit strength be a consideration.
