Would you be able to squeeze in tripples in on that beam, I wonder? Looking good, though. Personally I prefered the old three twins design, but hey ho. |

The mount is quite narrow, the IRL Tre kronor had a triple in front and was 16,7m wide, looking at photos it seems to be alot of space left
Looking good, though. Personally I prefered the old three twins design, but hey ho. |

Post subject: | Re: Imperial Swedish Navy |
There might be a problem in your SS report then. Report on screen here credits beam as 41 ft, while 16.7mtrs is more like 51-52 feet, which might lead to our confusion. Emile Bertin with triples was also very narrow like your design. It is certainly a different class when compared to the German Spahkreuzer type. An interesting design indeed. |

Post subject: | Re: Imperial Swedish Navy |
The Hugin looks good, your original Hugin drawing many moons ago got me into kitbashing ships so its nice to see it appear in SB all these years later! A very nice looking the design, the Bellona has good lines. The two triple 152mm might be overkill if she's working with destroyers but it provides some supporting punch. Another point regarding the torpedoes, is the forward mount a bit high being mounted on the forecastle deck? Your SS report says 4 torpedoes in 3 mounts, but I'm guessing you mean 6 tubes in three mounts. |

A nice looking design but 1,000 nm @ 20 knots? Seems a bit short... Can we see the entire SS report? |

You need to fix the values in your report Psilander. Beam = 41.01 feet ???? |

Beam = 41.01 feet ???? Thats correct 41,01ft=12,5m (same beam as Irl DD HMS Halland) This is the result with a incresaed beam to 15m
