Air taxi pilot reported the MYNN Runway 10 hold line markings are in an odd spot and are too close together for a jet aircraft to fit between them without hanging over into the runway area.

Narrative

Landed Runway 14 at MYNN. My PM and I had briefed a long rollout to avoid a lengthy wait for runway crossing into the ramp. We were instructed by ATC to exit the runway at Taxiway B and hold short of Runway 10. We exited the runway and immediately realized that the hold point for 10 was much further back than we anticipated; and that the space between the hold short line for 14 and 10 was only about 20 to 30 feet apart. There was insufficient room for our airplane to fit between the two lines without hanging over them. Additionally there were planes landing on both 14 and 10 so we were unable to cross the runway.We noticed when exiting the runway that the hold short lines were so close together it was hard to decipher which one was for what runway. And very easily could have been crossed if we were not as attentive as we were. A fatigued crew likely would have crossed unknowingly due to the expectation of the hold line for 10 to be closer to the runway.Cause: The runway hold line markings are in an odd spot and are too close together for a jet aircraft to fit between them without hanging over into the runway area.We taxied in as far as we could to maintain a safe distance from both runways. This probably meant that we were hanging over each line by approximately 5 feet. But we were unable to notify ATC due to frequency congestion and the fact that there was an aircraft landing on Runway 10 and Runway 14.Suggestions: A note in company app to alert crews of the odd placement of the hold line and the insufficient space for aircraft to safely clear both runways.
