The vanilla is there bud, here's the link
COAS CM V2 Vanilla Patch if for some reason this link dies, then its the sixth mod down in the link Goldhell posted.
Sordid, in CMV3 there's a little of RTBL there but it will be nothing like it was, masts been destroyed will take a little longer than villa and the higher the canilbure the quicker a ship will be demasted, and crew will take a little longer but again know where near like in CMV2 RTBL Patch, and again the higher the calibure the quicker the crew will be killed. I have tested and continue to test like mad with every moment of free time i get to make sure that the edits made are jist right and thats all that is in CMV3 of the RTBL, all calibure cannons and culverines have been reset to vanilla value's, ship and sail hp have all been reset to vanilla and in testing i was using the Crimson Blood which has 32 guns and i had 24IBS mounted, in one broadside of round shot i quickly saw the enemy ships hull damaged, the bar dropped alot and the enemy ship was a Frigate.
I know the RTBL patch for CMV2 was a joke and i have done a hell of alot of work to make sure that those mistakes are not made in this mod, like i said i keep testing everything out and to make sure i don't have files i edited that are not overwrote by any files from CMV3 i have reinstalled COAS and all files i have edited i have uploaded, so what i have is what is in the fix i uploaded for CMV3 and all tests have shown the resaults you would see in the base game, only masts and crew are there noticable changes.
Its up to you though bud, but i'm working my butt off to fix RTBL before CMV3 is released, i don't want another problem where a patch is made, this is it for RTBL its problems end here and from the looks of things those problems are pritty much close to been fixed. If i think it took me too long to demast a ship i will increase the value's and try again and keep doing it till i get the right resaults, the same with crew.
