I am building a submarine what is the best thing to use for a ballast?
Modern submarines use a variety of methods for ballast control. There are several factors that need to be considered:1. Overall water displacement surfaced and submerged2. Combined estimated weight of supplies and personnel aboard3. Fixed Ballast (weights, etc.)4. Main Ballast5. Trim BallastYour overall displacement estimate will give you the target for how much fixed ballast you'll need to add for an estimate to keep the boat at submerged depth at neutral buoyancy while surfaced (most of the boat below the waterline). Keep in mind that ballasting requirements are different for fresh and saltwater.You have to know the estimate of weight of all personnel, equipment and supplies onboard as well, since that also counts as part of the fixed ballast load. Knowing that allows you to know how much Trim ballast (used for maintaining more precise depth control and neutral buoyancy) you'll need to add or remove to achieve neutral buoyancy after you open the Main Ballast vents and submerge.Any ballast you use must be distributed evenly across the keel, or you risk being heavy forward, aft, port or starboard. This is why Trim Ballast tanks are used also - they allow for precision leveling of the boat after submergence.Without knowing your fixed ballast weight and how much Trim Ballast to add or remove, you can easily sink to the bottom or not submerge at all, though sinking is the more likely scenario. It's easy to sink a submarine - the trick is to get it back to the surface. As long as the number of dives equals the number of surfaces, everything's cool. If not, you're in for a bad day at work.
How do you change the overall Density of a boat?
I don't understand what you're asking, so I'll reply based on the literal meaning of your question. One way to change the overall density of a boat is to take it apart and make it out of a material with a different density. You could just add ballast or cargo.
Do you add the ballast and light wattages together?
No. Just make sure that the ballast you use is rated for at least as many watts as the lighting you plan to operate with it.
What does it mean when reefing your boat while underway?
For those using sails, it means reducing the area of exposed sail to add safety and stability to the boat. http://en.wikipedia.org/wiki/Reefing
How do you convert kg of Ballast into cubic metres?
1.75 tonnes 1,750 kg of ballast is one cubic metre, if its concrete then you'd need to add 300kg of cement to mix this to the right ratio for a foundation.
Which boat should stand on when one boat is overtaking another boat?
I would add that a smaller boat overtaking a larger boat or ship should always give way or alter its course because a larger boat or ship cannot quickly slow down or change its course. The larger vessel already underway should continue, without the added concern of an overtaking smaller boat causing a collision.

How do reduce density of concrete?
Add ballast that is less dense than the gravel/sand in the concrete such as LECA (Light Expanded Clay Aggregate).
How do you build a boat?
you grabb some wood and put it together and make it look like a boat h - boat are gay than add a seat

Do you add a fuel additive to a 1991 ford boat engine?
No
Do oil Tankers travel empty?
Almost. They need to add some ballast to keep enough of the prop and the rudder submerged, but the big holds are empty.
