it can hold 50 pennies depending on the base of the boat and also depenidng on the sides now if you have a 20 by 20 then may be a 100 or 150 pennies it may hold
A skiff is a small boat - so an aluminum skiff is a small boat with an aluminum hull.

Depends on how big you make it.

A design with a wide base and tall walls is desirable for an aluminum foil boat. You want enough surface area supporting the pennies so they will keep floating and to not compromise that for wall height to keep water from enter your vessel.

Only one penny is required, if it is moving fast enough to puncture the hull. If you are talking about the weight of the pennies, then aluminum boats come in various sizes, so they do not all have the same penny carrying capacity. A ten foot long aluminum rowboat can carry a million pennies without sinking. Try it.

A skiff is a small boat - so an aluminum skiff is a small boat with an aluminum hull.
The hull on a boat is the body of it. It is watertight so that no water leaks in and sinks the boat.

The question depends on what the aluminium is floating in. It is denser than water so will sink a block will sink in water without any pennies. If, on the other hand, it is shaped (like a boat) then the number of pennies required will depend on the shape.
It depends on the size of the boat.
I would think a canoe or a cruise boat because a canoe can keep level while a triangle or other shapes might tip over due to unbalance. However a cruise-ship is deep and would hold more pennies.
If the boat sinks, too many people are on it.
