Rolly custom steel motorboat

No, not a boat broker although I do do boat deliveries, but that is also unrelated.
I'm trying to help you resolve your dilemma.

If it "might happen" I'm curious what boats you're considering.
Maybe you're not really considering any other boats.
If that really is the case then I think you should remove all the superfluous superstructure and
return the vessel to its original design and roll period.
No?

 

Correct. I am not considering any other boat. That is not why I am here.

Spending a quarter million dollars on removing/rebuilding this boat to the original design, does not make financial sense. This is not a ' classic boat '.

I am here on this forum to get ideas of a possible solution for roll reduction and stability improvements.

 

Ad Hoc

I know you are busy and I only want some confirmation from you.
I have read this post several times and I am convinced that this is the only feasible solution for me, to address the rolling/stability issues. I am saying this because of my limited budget. This will still require investment and efforts, a good welder, a shop, and plenty of time; but I think it is doable. At least, this is the best way to go with a simple budget.
Let me know if you agree and if there is any additional advice you have? Thanks.

 

One easy way to reduce rolling on any boat is to put a pair of these in the water Rock Stopper — Channel Islands Marine https://channelislandsmarine.com/rock-stopper. We use them on our 15 ton sailboat and the difference was night and day.
