Water Ballasted Boats
Water Ballasted Boats
Are there any Builders in North America building water ballasted boats.

I've got concrete ballast in the stern of my boat. Don't know for sure why it is there other than a previous owner who was doing survey work may have had it put in to reduce the rocking. I have a deep vee hull. It was really the wrong hull for a survey boat.
I have 7 large pieces of poured concrete with 3/8 flatbar running through the center of them. The concrete is at least 6 inches thick. The concrete rectangles fit between my longitutinals and a bolted to the ribs of my hull structure. Amazingly the concrete does not touch the hull.
I am considering removing the ballast because I don't think it was original with the boat, but don't know for sure. The factory told me they usually don't put it in, but my boat is 23 yrs old, so they no longer had the specs on my boat.
Water ballast seems a lot easier to remove and replace. I wonder how many alloy boats actually need ballast though....

Hi
This is a 28ft boat we installed a ballast tank in this boat.
The boat holds 350gallons (500miles at 50knots) of fuel in 2 tanks. When the fuel tanks are full the ballast tank is not needed.
On of the concerns the owner had with his previous boat was the difference in the ride between a full fuel tank to an empty tank. He would tow the boat around on the trailer with a full fuel tank even though he may only have needed 40 gallons for a fishing trip. With the ballast tank he keeps just enough fuel in the boat for fishing then is able to add 1000lbs to the boat after he is out on the fishing grounds.
Sincerely
John

With unpainted Alu the look of the weld is critical, particularly at high focus areas such as the transom.
It is noticeable at boat shows people gather around the transom, so this area becomes the area of high focus. The photos show the difference between a boat being built, that will be painted and one that is not.
In one instance a Mig welder has been used in the other a Tig (in the high focus areas only), I am curious if this is similar in North America or whether because of its speed Mig welding is used exclusively.
Note: The tubes that are visible in the keel of the Hull are flood tubes that fill with water when the boat is stationary increasing the boats weight.
This allows the designer to increase the deadrise of the boat with out fear of the chines loosing contact with the water and becoming unstable.

Hi Greg.
We have spent an inordinate amount of time on R&D. While we have had a lot of inquiry, a great deal being from the eastern states we have not been in a position to supply, that is currently changing.
Thanks for the use of the photo and by the way what is you experience with the flood tube?
I imagine the boat has a 23 degree dead rise, which with out the water balast would make it unstable at rest, is that a fair assessment?

Wayne - very happy with the stability of the Fisher. Yeah you are right, mine is one of the Maxi series running 23 degrees at transom. Before I pulled the trigger I looked at all the builders here in SEQ and I believe the Fishers represented the best value for money with a ride second to none. It was very close with Noble but they priced themselves just out of my budget and were a little bouncy at rest with 24 degrees and just the stepped hull. They do ride nicely though.
As you would appreciate there is a lot more in the hull design than the deadrise and ballast tubes. Col has been building plateys longer than just about anyone in Oz and he has these boats just about right.
All the best with the business - you should have no problems with orders once then name is out.
Cheers
