On the Britannic, gantry davits were added... Why, on the Olympic, were the same davits not added during one of her post-Titanic refits? It says on www.hospitalshipbritannic.com that the Olympic was fenced in by a wall of boats, but Britannic left the deck spacious and uncluttered, or something like that...

Did White Star just consider it to be no big deal, or was it not plausible?

Can someone shed some light on these? Thanks!

Daniel,

There are a number of reasons. Firstly, Britannic's breadth and metacentric height (crucial for stability factors) were different to Olympic; she was wider. Thus she could cope with the extra weight that these davits would bring.

As Olympic had already been built, the installation of gantry davits would not only be horribly expensive, but may well have had an adverse effect on her stability with all the extra topweight, even if she had been fine beforehand.

Furthermore, Britannic's superstructure had to be strengthened to cope with the additional weight of the davits and the concentration of weight at eight specific points, additions such as girders being installed. Olympic would have needed similar modifications, but as she had already been constructed and outfitted this would have been impractical, as well as uneconomic. Had gantry davits been fitted without modifications, not only would her stability have been in danger, but also it would be inviting structural problems within a few more years of service.

One final point is 'looks' -- Olympic was widely considered to have a beautiful profile, and gantry davits would hardly have improved it. They didn't for Britannic, but by the time she was built White Star was not only trying to outluxe the new 'Imperator' class German liners, but was trying to construct one of the safest vessels afloat.

Best,

Mark.

Thanks... I did think about the 'looks' aspect; I have a copy of Ken Marschall's Britannic picture and the davits don't seem to be the best looking things... But I never thought of stability... I guess I forgot how much those gigantic davits would weigh!

Thanks again,
Daniel Odysseus

If I do recall, though, I had seen the Welin davits with stacked boats on other ships, like Berengaria. Why couldn't they do this with Olympic?

I thought they actually did stack boats on the Olympic--didn't each lifeboat (post-Titanic) have an Englehardt collapsible underneath it?

I stand corrected. However, there are some photos of her sporting one boat per davit rather than the stacked two. Sorry for my confusion

Yep...though immidiately after Titanic, they used some of those Berthon collapsibles borrowed from Royal Navy stores. The Englehardt's and the additional davits came later. After the refit if I recall correctly.
