1915 Bavarian Tender

[Kaiser Kirk]

The Salmon class is intended serve as a collier/tender to allow the Bavarian navy to dip its toes further out in the Med, or even further afield.  The vessel also serves as a testbed for large Bavarian marine diesels and turboelectric drive.

So...what did I goof :)

Enter percentage of bunker tonnage devoted to coal fired boilers

A large tender/collier to support the small Bavarian fleet on forays into the Med.

Miscellaneous weight :
4500t - The 4500 tons dedicated to fleet support and repair will support 18,000 tons of shipping, also known as the entire Bavarian navy.
25t - 100nm range radio is fitted.
20t - spare torpedos
20t- uncommitted reserve

The 3,421ton bunker full load contains over 2500 tons of coal for refueling.

The ships propulsion is 4/5 conventional coal boilers, 1/5 M.A.N. 2,000hp diesels. The diesels alone will propell the ship at over 11.1 knots.
The new turboelectric drive system is tried out in this ship as well.
