To start with I'm a cruiser & not much of a sailor...that said I'm trying to understand the rigging
of my (new-to-me) 1994 Catalina Morgan 45 sloop
. The mainsheet is rigged at the outer end through blocks to the traveler and then into the cockpit
at the rear...this is what I'm used to. However the other end is rigged through the boom to the mainmast and then back into the front of the cockpit
with the main halyard
and topping lift
(I think that's what you call the line that holds the boom up when the sail is not hoisted). My question is why I need the mainsheet rigged to the cockpit at both ends? The answer matters because I'd like to use the space and sheaves for a reefing line instead. What am I missing here?
