My understanding is there have been 3 Boatmate trailer iterations over the years since the 200 came out. The newest iteration being in 2020. My 2020 trailer bunks are completely different than my 2019. I load/unload on a fairly steep ramp which seems to cause this problem. The new bunk design on my 2020 seems to be significantly better.
I fill up my 200 on the trailer and on a slope. If the trailer is pointed downhill, I have this issue. If it's pointed uphill, then I have no issues. Not sure why, just my experience.
