A second, much less stable conformer is the boat conformation. This too is almost free of angle strain, but in contrast has torsional strain associated with eclipsed bonds at four of the C atoms. Rotate the molecule in the CHIME image to show this just like a Newman projection. In addition, a steric interaction of the H atoms inside the "bow" and the "stern", known as the flagpole interaction destabilises the boat.

The most destabilizing interaction in the boat conformation of cyclohexane is the flagpole-flagpole interaction.
The boat conformation of cyclohexane is one of the many possible conformations that cyclohexane can adopt. It is named so because it resembles a boat with the two ends pointing upwards and the middle portion dipping downwards. In this conformation, there are several interactions that contribute to the overall stability or destabilization of the molecule.
Eclipsing Interaction:
The eclipsing interaction occurs between the hydrogens on adjacent carbon atoms. In the boat conformation, the hydrogens on the axial positions of the boat are in close proximity to the hydrogens on the equatorial positions of the boat. This results in a slight overlap of electron clouds, which leads to destabilization. However, this interaction is not the most destabilizing one in the boat conformation.
1,3-Diaxial Interaction:
The 1,3-diaxial interaction involves steric hindrance between two groups that are both axial and separated by three carbon atoms. In the boat conformation, there are two sets of 1,3-diaxial interactions. One set occurs between the hydrogens on the axial positions and the hydrogens on the adjacent equatorial positions. The other set occurs between the hydrogens on the axial positions and the hydrogens on the opposite axial positions. These interactions contribute to the destabilization of the boat conformation.
1,3-Diequatorial Interaction:
The 1,3-diequatorial interaction also involves steric hindrance between two groups that are both equatorial and separated by three carbon atoms. In the boat conformation, there are two sets of 1,3-diequatorial interactions. One set occurs between the hydrogens on the equatorial positions and the hydrogens on the adjacent axial positions. The other set occurs between the hydrogens on the equatorial positions and the hydrogens on the opposite equatorial positions. These interactions also contribute to the destabilization of the boat conformation.
Flagpole-Flagpole Interaction:
The most destabilizing interaction in the boat conformation is the flagpole-flagpole interaction. It occurs between the hydrogens on the two ends of the boat conformation, which are in close proximity to each other. These hydrogens experience a significant steric hindrance and repulsion due to their close proximity. This interaction results in a high energy barrier and contributes to the overall destabilization of the boat conformation.
In conclusion, the most destabilizing interaction in the boat conformation of cyclohexane is the flagpole-flagpole interaction. This interaction occurs between the hydrogens on the two ends of the boat conformation and leads to a high energy barrier. The eclipsing, 1,3-diaxial, and 1,3-diequatorial interactions also contribute to the destabilization of the boat conformation, but they are not as significant as the flagpole-flagpole interaction.

Flagpole interaction generally raises the strain and then energy in cyclohexane(boat conformational str). you can imagine this as two hydrogens at pole position(1,4) and the interaction between them.
