Here's a couple teaser pictures of the bow of the Time Bandit for comparison.
Never having watched the
Deadliest Catch (lack a satellite dish to receive those Reality TV committed channels) I cannot say what the hull of the
TIME BANDIT used to look like.
But this protruding cylindrical bulb to me looks like having been retrofitted later, post-delivery so to speak.
As the diameter of its cylinder doesn't look too wide and the structure of cylinder and semi-sphere quite sturdy, I think the perils of slamming aren't excessive, despite the Alaskan notoriously heavy sea.
If it helps cutting fuel costs in moderate sea states.
