    In an article, by a guy that designs canoes and seakayaks, it said that the Navy had determined the optimum angle (from verticle) for the bow and that all their ships were close to this angle. 17 degrees rings a bell with me. Anyone know about this?

    I have a hard time believing that any one angle is optimum for all boats. Too many other variables that would impact it for a single angle to be best.

    Optimum angle for what? Wave piercing is very different than cargo, or sailing, or... There is no optimum anything for all boats.

    Since wars go on no matter what the weather, I think it was for performance in stormy seas. If you look at navy ships, it does seem like all their bows look about the same. I'm not sure what to think of this. I guess you'd have to ask the Navy.

    The bow angle developed by the US Navy was for surface ships that preformed within a very specific envelope. This will be in the 25 to 30 knot range and the bow angle is just a very small portion of the "discoveries" they made in regard to WL Entries.

    Looking at the much more raked bows of Russian ships and some other Navies, there seems to be basic disagreement on ships with similar performance envelopes.

    I suspect most of the Russian navy, also have bows designed to bash it's way through thin ice and obnoxious tree hugger boats, that happen in their path.

    Great guess, even if it turns out to be wrong!

    Okay, you had a problem with the tree hugger comment?

    That must've been it. Chuckle, chuckle. Anyway, I liked the sharply swept bows on the Russian ships.
