For no Tuner, for anyone who wants Yashi's WR, although you can't skip the Delivery Bag, you can still skip the Medli Bottle. This is really only worth it on the English version, but it's still faster on both versions.
On English: saves about 0:50 + 30 seconds at Ghost Ship
On Japanese: saves about 0:15 + 30 seconds at Ghost Ship
Route:-Get the Wind Waker.
-Do Zephos Skip.
-Get Storage off the edge facing the left pillar near Zephos (if you fail storage, strafe right, climb the ledge, and strafe back to the storage spot, as this is the fastest way to retry storage)
-Get Camera Lock and strafe into the water. When you start superswimming, you'll have 1-2 seconds to charge up with constant air refills before you sploosh, so you should shoot yourself away after about 1-2 seconds.
-Superswim to the submarine and get the submarine bottle.
-Savewarp, sail to Bomb Island, get water in your bottle when you reach the island.
Now here's where it gets tricky. Since you want to save 30 seconds at Ghost Ship, you want to arrive at Dragon Roost after it turns night. So since you have to wait for it to turn night, you may as well change the wind to South since you have to do that later anyways.
-Do a Wind Waker dive and get storage but don't cancel the Wind Waker. Instead, play Wind's Requiem and change the Wind to South. Since you change the wind using the glitched Wind Waker state, the in-game time will continue to pass.
-Do another Wind Waker dive, get storage, and cancel it this time.
-Roll over to the area near the vines, get Camera Lock, and sidehop into the water.
-Superswim to Dragon Roost. You can either drown in the quadrant or reach the island. Unlike the Delivery Bag skip, it does not matter if you drown or not because you already did Zephos Skip and do not need KoRL.
-Do Rock Skip, talk to Quill, get Delivery Bag.
-Roll right to the DRC entrance and pour water on the bomb flower right away.
-Pick up bomb, blow up rock, beat DRC with the chest storage route (
