Indeed God hath created everywhere around this Gate oceans of divine elixir, tinged crimson with the essence of existence and vitalized through the animating power of the desired fruit; and for them God hath provided Arks of ruby, tender, crimson-coloured, wherein none shall sail but the people of Bahá by the leave of God, the Most Exalted; and verily He is the All-Glorious, the All-Wise. (Selections from the Writings of the Báb P57)

Why only Baha'is sail on Arks of Ruby and what does to sail mean?

It is allusions to the afterlife. We will be interconnected to each other. "Tinged crimson with the essense of life...." seems to refer to blood and literally life possibly reference to life after death in an energy state or some state related to physics which I don't understand and once created, the human life via soul goes on forever, and animated by the power of the fruits or fulfillments of our lives. The ruby ark is a state of being one obtains from being a Baha'i and faithful. This is how I see it, my idea only just looking at it without looking at other sources.

From my reading of other passages the elixir can represent the transformation of one's self or the Bab Himself.

These oceans could be the words of God flowing from the pen and tongue of the Bab, transforming and renewing the world.

I looked up ruby online in the Selections from the Writings of the Bab:

"NO created thing shall ever attain its paradise unless it appeareth in its highest prescribed degree of perfection. For instance, this crystal representeth the paradise of the stone whereof its substance is composed. Likewise there are various stages in the paradise for the crystal itself… So long as it was stone it was worthless, but if it attaineth the excellence of ruby—a potentiality which is latent in it—how much a carat will it be worth? Consider likewise every created thing. "

Here ruby represents perfection. Elsewhere the Bab writes:

O PEOPLE of the earth! By the righteousness of the One true God, I am the Maid of Heaven begotten by the Spirit of Bahá, abiding within the Mansion hewn out of a mass of ruby, tender and vibrant; and in this mighty Paradise naught have I ever witnessed save that which proclaimeth the Remembrance of God by extolling the virtues of this Arabian Youth. Verily there is none other God but your Lord, the All-Merciful. Magnify ye, then, His station, for behold, He is poised in the midmost heart of the All-Highest Paradise as the embodiment of the praise of God in the Tabernacle wherein His glorification is intoned.

Perhaps the symbolism is the same for the above.

I doubt its an allusion to life after death. That's my opinion.
