Alternative Method: Cheating
Option 1: Warp to Birth Island
Should all else fail, there are underhanded ways of getting to Navel Rock- namely, Gameshark codes. If you own a Gameshark or have a Visual Boy Advance emulator, input the following code:

Fire Red/Leaf Green
Warp to Birth Island Automatically
554D9257
D0472EF8
Once you have the codes punched in, step through the nearest door or cave entrance you see. You'll be taken to the port for Birth Island instead. Disable the warping code as to not start a repetitive loop appearing at the port. Instead, you'll be able to access the entrance to Birth Island after walking out from the port.

Option 2: Buy a Ticket
The second option is a touch more convoluted, but it isn't as cheap as warping straight to Birth Island. First, input the master code that matches your game version into your Gameshark:

Master Code
Fire Red
72BC6DFB E9CA5465
A47FB2DC 1AF3CA86
Master Code
Leaf Green
72BC6DFB E9CA5465
56671F3A 6F4F4D6B
Next, input the following code to prevent the game from crashing:

DMA Code
8D671FD9 6F6BEFF2
78DA95DF 44018CB4
Once you've added this code, you'll need to add another version-specific code. This code is designed to allow the programming for the items sold in any shop in the game to be switched out with an item of your choice, so long as the code remains active:

Shop Code
Fire Red
0E12F25C BC489609
141BB87C 83D7018F
7A063220 5D82DF58
Shop Code
Leaf Green
EAEF00BE 85EA8374
141BB87C 83D7018F
194F7975 5E68B89E
Now, add this code to the list already punched into your Gameshark:

Aurora Ticket Replaces Shop Items
641B9F5D 3A0D0482
Finally, there's one more code to ensure the sailor at the Vermilion City port recognizes you have a Aurora Ticket:

Sailor Notices Event Tickets Code
07CF2578 E43B4EBF
Adding all the codes listed here will make it possible to obtain a Aurora Ticket and legally go to Birth Island via a Seagallop Ferry.

Once every code is entered into your Gameshark, head into the nearest shop and make a purchase. Instead of the normal stock being displayed on the list of items available for purchase, everything will be replaced with an option to buy a Aurora Ticket for free. Purchase one ticket and leave the store. One check on the Key Items screen will confirm you now have a Aurora Ticket.

Note: if you were to turn the codes off but the shops still offer the Aurora Ticket, save the game and turn it off to clear out the effects they had on the game programming. Turn the game on, and the shop items should return to normal, but you'll need to re-enter the master code, DMA code, and "Sailor Notices Event Ticket" Code.
