When refitting a ship, you have the option of bulges. are these the same as anti- torpedo bulges? Bo they add torpedo protection? en.wikipedia.org/wiki/Anti-torpedo_bulgeAlso, when you add them it says "-2 knots, but if you replace the ships machinery and increase the ships speed by two knots, it changes to "0 knots". Does it mean that you are back to the original speed of the ship or is it two knots faster? For example, if my ship is original 19 knots and I add bulges and do nothing else, the rebuilt ship will have a speed of 17 knots, but if I rebuild the machinery and increase the design speed to 21 knots, will the rebuilt ship be 19 knots or 21 knots? (I know I can just test the second question, but I thought I would ask it since I was asking the first question). |

I was under the impression that the bulges are for anti-torpedo uses, and effectively raise TDS by one. The added displacement is a happy side effect of the additional empty space. The only part I'm not confident in is what happens when you bulge a TDS 4 ship - do you end up with an effective TDS 5?
When you replace engines along with the bulges, they automatically raise engine horsepower to compensate for the extra drag. You can watch this happen by observing "engine horsepower" as you check and un-check the bulges option. If you don't replace engines, you're stuck with the original horsepower so the extra drag reduces ship speed.

Air Filled Bulges are certainly less effective but they do still protect against torpedoes

Bulge's effect as TDS was in RTW 1, this was revamped in RTW 2 to be just free-displacement, nowhere does it mention that Bulge retained the ability to serve as TDS. Technically, bulges are generally filled with water and reinforced with bulkhead behind it to absorb the blast, which can be seen as investing the displacement from the bulge into TDS. An empty bulge is just additional air filled space, which gives the ship more floatation but not going to be very useful against torpedo unless designed for that purpose. Little problem with that: you can't change torpedo defense level in a rebuild. |

What's your source for no torpedo protection from bulges? |

What's your source for no torpedo protection from bulges? P 68 of the Manual Stating that bulging now adds displacement. The "Now" without some quantifier like "also" made me assume the displacement effect replaced the original page 10 comments with regards to how bulging used to work. This is most likely a misunderstanding on my part, I've deleted my original comments to avoid causing confusion, my apologies. |

Some bulges I've added do not reduce the speed at all, wonder what causes that to happen. I've gone to rebuild a ship, added bulge for free displacement and no loss in speed (for example -0 knots +500 displacement).

I've gone to rebuild a ship, added bulge for free displacement and no loss in speed (for example -0 knots +500 displacement). I take this happens when you are rebuilding the engines at the same time? You will note that the final outcome is a vessel no faster than before even though you have boosted engine power. Still it can be quite useful during a treaty or similar to do this. |
