here is Mudyug after 1987 with the new Tyssen-Waas bow. I made the drawing using the available pictures without any specific reference. ![[ img ]](http://i540.photobucket.com/albums/gg335/lazer_one/Russia%20IB%20Mudyug%201987.png)

Very nice work. That is one ugly bow! |

DTIC has a seakeeping study wherein they apply these icebreaking bows to a LSD-41 and FFG-7 hullform (with predictably horrific results). It also has a plot of the shape of Mudyug's altered hull. http://www.dtic.mil/dtic/tr/fulltext/u2/a243112.pdf |

This bow, following a scientific approach, has been applied 3 times.. And all 3 experiments confirmed an orribile result! |

Aw, come on, the slamming is much worse but the stability is improved in both cases... What became of these boats since the 80s if the performance was that bad? Anyway, the drawing is really great, I like the detail of the new bow. One doubt though, is it normal that the flag on the stack switches from Soviet to Russian already in 1987? |

It's a coastal icebreaker. Heavy-weather seakeeping is not so critical as it would be in a blue-water navy ship that does not necessarily have the option to heave to and keep steerage when the going gets foul. |

OK, thanks for clearing that up.So all that DTIC study was saying, in essence, is that you shouldn't try grafting brown-water bows on blue-water ships, icebreaking or not... Apparently that needed spending computer modelling time on

Opps!!!I took into account the date of bow modification but flag is much more recent... |
