Will his sons (heirs) bother about a treasure if they are rich then? Why telling them cryptic tales they don't understand?
Firstly, the estate would be divided in three - you'd only be getting a third of the fortune. Sir Francis appears to have been building a condition into the puzzle: if you don't cooperate, everyone loses.

Sending his sons to the Caribbean is definitely a nice idea here, but those rich and lazy guys sure won't go.
They will only be rich if they can find the secret treasure stashed in the monument. Until then, if they remained lazy, they would gradually find themselves on a downward spiral.
Actually, as the treasure remained hidden, and the present-day Haddock is not a man of great means, we could assume that that is what happened: the brothers didn't cooperate, the money ran out, the estates were lost, and the family had to resort to working for a living.
As mct16 and Balthazar are saying above, setting the challenge in the manner of a riddle to be solved wasn't really a clue to the treasure under the sea, it was a test to see if the brothers had been listening to what they had presumably been told by their father.
Has a teacher never given you one of those trick tests, where you are given a long list of tasks, the first of which is to read all the instructions. This is then followed by long winded arithmetic problems, adding this, dividing that, or being given some complicated diagram to construct.
However the
last instruction is to ignore all the previous instructions, barring the first, if you have now read all of them. You are told to sit back and fold your arms. The only way to get to do the last instruction is if you diligently follow the first.
I imagine that Sir Francis's scheme works in a similar fashion.
The sons will be rewarded if they have listened to what they were told at the beginning, and if they work together they can by-pass the rigamarole of a long, fruitless sea voyage.
He might also have thought that if they had the wisdom to discover the treasure in this manner, they would have the wisdom not to waste it, and use it wisely.
He may have seen an additional outcome: that if they did cooperate, but undertook the voyage, they would still be learning to cooperate and work hard as mariners, which in itself would be valuable and could have been why Haddock was still sailing on the
Karaboudjan centuries later.
