turtle ships do not have any attack bonusses, so they just have 50 mellee attack.
They are the only boats to not have bonus damage versus rams, or against buidlings.
Unlike one might expect they are very different from the cannon galleon, in that the latter do have bonus damages: significant anti building damage and anti-siege damage and a small bonus damage versus most land units.
Also, turtle ships receive bonus damage from fireships, but in turn their extra mellee armor would block some of the base mellee damage of a fire ship. (the fire ship is another example how weird navy is programmed in this game: the fire ship has mixed mellee and ranged damage)
Lastly, looking at the turtle ship armor: they have anti-ship armor (all ships have this), they have good base mellee and ranged armor (which is the only armor that is shown), they have 0 anti- turtle ship armor (which has no effect at all i think?!) oh, and they do also have the unique unit and gunpowder class, so they would take extra damage from condotiero and samurai.
Take home message: Navy is weird, dont trust the shown attack value, and don't rule out some unexpected counters.
