"... The Ship appears to have no bow ... Aratos wrote:

Sternforward Argō by the Great Dog's tail // Is drawn; for hers is not a usual course, // But backward turned she comes, as vessels do // When sailors have transposed the crooked stern // On entering harbour; all the ship reverse, // And gliding backward on the beach it grounds. // Sternforward thus is Jason's Argō drawn.

This loss of its bow is said to have occurred

... when Argō pass'd // Through Bosporus betwixt the justling rocks -

the Symplegades, the Cyanean (azure), or the Planctae Rocks at the mouth of the Euxine Sea. Yet Aratos may have thought it complete, for he wrote:

All Argō stands aloft in sky.

and

Part moves dim and starless from the prow // Up to the mast, but the rest is bright;

and it has often be so illustrated and described by artists and authors ..." (Allen)

We have seen that in rongorongo a glyph facing backwards as a rule defines the end (the 'poppa'), for instance in Gb8-5 and Qa6-26:

Gb7-31	Gb8-1	Gb8-2	Gb8-3	Gb8-4	Gb8-5

Qa6-26 (231)	Qa6-27	Qa6-28	Qa6-29	Qa6-30	Qa6-31 (236)

At ihe tau I have cited Starzecka:

…to enter a war canoe from either the stern or the prow was equivalent to a 'change of state or death'. Instead, the warrior had to cross the threshold of the side-strakes as a ritual entry into the body of his ancestor as represented by the canoe. The hull of the canoe was regarded as the backbone of their chief. In laments for dead chiefs, the deceased are often compared to broken canoes awash in the surf ...

When a ship goes down it therefore necessarily means its Captain (its head) must go down too.

To beach a sinking ship will save the situation. The front may be under water but the poop will remain on dry land. In Qa6-27 both arms are held high and the hands are like dry crotches.

When Aratos wrote that the Gread Dog's tail was drawing Argo backwards (a sign of 'back'-to-back) into a safe harbour it corresponds very well with what we can see in Gb5-29 and Gb6-1:

Roto Iri Are (13 * 29.5 = 383½)
					23
Gb4-33 (354)	Gb5-1	Gb5-2	Gb5-3	Gb5-4
Gb5-28	Gb5-29 (383)	Gb6-1	Gb6-2

The Great Dog ought to be Canis Major (with Sirius) which rises one hour earlier than Puppis (the Stern). The tail of the Great Dog explains the left part in Gb6-1 and as a whole the glyph will illustrate a dog. The similarity with the 'climber' coming 60 days later is evident:

Gb6-1 (384)	Gb8-2 (444)
