The egg-shaped lifeboat that was going to America

The voyage by Ole Brude and his crew from Ålesund, Norway to Gloucester north of Boston in a egg-shaped covered lifeboat in 1904 has been mentioned here before.

Now a documentary about this adventure has been made. The first part was shown NRK1 TV today and the second part will be shown tomorrow:

Unfortunately it is only available in Norway and only with Norwegian text (AFAIK)

The documentary was made by a local company:
BTW; the commentary are spoken in the local dialect.

23 of these “eggs” were built, but the idea did not catch on among shipowners, or Maritime Authorities before in the 1970s.

The idea did not catch on…at the time. He was ahead of his time considering ships being built today are all enclosed.

Apparently there was another Norwegian that had the same basic idea even earlier than Ole Brude. Capt Dønvig’s Life-Saving Globe was developed and presented at the World Expro in Paris in 1900:

Like Ole Brude his idea came about after being involved in a shipwreck;

This invention differ in shape from the Brude Egg, but is otherwise similar in that it involves an enclosed “rescue capsule” in steel.

Why is nothing about this earlier invention is mention in the documentary about Brude and his invention?
Of course the documentary is about the voyage across the Atlantic, but I have not seen it mentioned anywhere in the history of the Brude Egg. (I could have mist it)

In any case, none of these inventions gained acceptance before in the 1970s.

Capt. Dønvig’s Globe is more like that of the Whitaker Capsule:
