Why Sentenal exists.

Running anything on the water used to take a small army: people laying marks, hauling anchors, and volunteers you cannot always find. If the wind shifted, you started over.

The robotic marks that existed were built like research projects and priced like them too. Braedyn had stood on both sides of that gap: coach, race official, and the person who saw what the technology could be if someone designed it for real conditions and real budgets. Sentenal is the answer. Simple, modular, reliable, and priced so the organisations that need it can actually have it.
