here are the piks promised.

this will be my second project for the winter.
Thanks for the pictures. It is unreal this mod will allow to corner fast with black jack and no turn fins!!!!
BDW, what speeds are you getting on your bj? I would like to know average speed cornering if possible please?
I will get 50MPH on my bj but half throttle or less if the water is like mirror on turns hoping it wont flip.
Thanks again, cool staff

Has anybody tried to add strakes/rails to the bottom of the sponsons of the black jack. seen this in the build section for the scrach built 30" cat. post #140. they aren't running any turn fins,and don't have the last step filled in and seem to be running just fine.

my bj is about 42-43 on 4s, and now will enter corners at that speed. btw i ended up epoxying in wood plates as my double side tape didnt hold up to the water after 2 runs.

Do I need to make it flush with the boat step and even with the middle step?

[6S HYDRO]

yes

im going to try this for sure! for the nerd in me can anybody try to explain why this works? i do know that stepped hulls are speed specific but why does this help in the turns?...good tip though! cant wait to try it out.

[Stephavee]

Nobody can give me any insite as to why this works for this hull?
