I think I may be a party pooper as welI. I like having separate lines for my sheets, makes it much easier when running through different blocks (inboard vs outboard), and sail changes are also much easier. Untieing the lee sheet, rerunning, retieing, tacking and doing the same to the other side. Maybe it’s because we have very inboard shrouds on our rig, but I typically don’t have knot hang up issues on rigging. Being electric we sail everywhere and have tacked thousands of times. Most common hangup is the sheet caught on forward cleat, a single sheet wouldn’t help there.
Also, we are huge fans of the dodger. It’s a bit restrictive when moving forward/racing but our boats are wet rides, especially if the swell is larger than 2m. We sailed from Samara, CR to Puntarenas, CR without our dodger (en route to get the new on fitted) and just got soaked. We were hove to for about an hour through a couple of squalls (dumping rain) and realized how much we missed having the dodger. Then again, I can see the bow easily from the helm as we are tiller steered and the helm position is forward in the protection of the dodger (with both main and jib sheets in arms reach) and not hung off the transom like the wheel steered boats.
I have probably seen thousands of gallons of water wash over our decks, we have filled the cockpit like a bathtub more times than I can count when our stern wave meet following seas just right (it takes a full minute before the water completely drains, open transoms are nice for that). We now put the hatch board in when the seas build to 2m from behind. Weather clothes would probably be nice.
In the end, it depends on what you are doing with these boats, and how much comfort is required.
