Added weight

Bit of a how long is a piece of string question. What sort of impact would 150kg of weight have on a boat capable of 75mph. Maybe someone who has a similar sized bow tank, might know how much speed they loose on fill up??

Your amount of loss in speed will be very dependant on where you put the extra weight. Right back at there transom will make little difference, right up front, a lot!

For arguments sake. 150kg upfront and also 150kg equally balanced over the whole boat. 8.1 stepped hull rib. 250 rude

The question didn't say he was asking for a bow tank comparison, it just said maybe someone with a similar weighted bow tank can comment...

I would say that you'd see less speed loss with a stepped hull than with a traditional V when the weight is placed fwd. weight up front is a top speed killer on a regular V.

Bow tank

If the bow tank is right in front (lets say 2 feet) it won't need to be as big and you won't loose as much speed, it's more about balance than weight

The boat has a huge bow tank. Over 6ft long and the width of te bost from bow. But it's decommissioned. It's a general overall effect of weight, such as in deck and structure I am interested in.
