1.14.4 tickEntity lag - nms.EntityBoat? (timings included)

Hello, this is my timings report: https://timings.aikar.co/?id=db0187c7db6147a0918421cdf9d7dbf0

After i removed the plugin lag assist which will auto toggle physics to off, the tps drop to 3, by checking the timings report suggest 485% lag due to tickEntity - nms.EntityBoat

I want to know what does it suggest? too many boats? not possible, and how to eliminate the lag

Probably someone have a huge concentration of boats somewhere which make your server lagging
