Rib Ballast

[Sonar]

How would one introduce ballast to a rib.?
The only way I can think off is to drill a small hole 3/4" and pour in a mixture of lead shot mixed with resin.

However would there be any way of knowing if the mixture has adhered to the hull.

Unlike a hard boat.
Mixing shot blasting sand and resin then putting the floor back down.


Is the only other option lifting the floor and laying the ballast then a few lams over the top to hold it all in place.


Hopefully I won't need any but I just have to ask the question.

Assuming that your talking about putting ballast in the bow - a box of some description that holds your anchor with a bit of chain secured into the bow is a good place to start.

I call my ballast the missus, it is even easily moveable

Surely you need to be certain of the amount and location before doing someting so tricky to undo. Does your boat have problem that are not easily remedied some other way?

I don't yet know as I am still on building it.
Just asking the question
I feel sure I have everything right so far.

It will be awhile before it hits the water.
I am keeping as much as low as I can

Fuel tank may be as much as 180ltrs that's under the floor along with when completed
batteries sett as low as i can..
It's a wait and see thing...

Fit a water ballast tank in the bow like the atlantic 75s ,

Fit a water ballast tank in the bow like the atlantic 75s though youll need a tank and a pump ,

That's a good idea..

I have left a space for under the deck just rear of the hard nose for storage with a floor hatch I could use the void
for that using a portable fuel tank bag

Have a word with cooke on here he may be of some help with ballast systems.

Thats perfect .. put your anchors and chain in there if youve got room and make sure its well protected by some rubber conveyor matting though to protect the hull from the metal work, you can get some lead shot or similar as extra weight if you need it but I would doubt that .. unless you do go for the 150

If you still got some design choices left, get the fuel tank as far forward as you can too , you will never regret that.

The last hull I used had this configuration, it allowed me to set the console further after, which gave a much smoother ride for the driver than any other 5.7 Ive used .. the boat in question had a fairly shallow dead rise by comparison to some Ive had, but handled like a peach because of the balance
