Not really - its is 165lbs BW was 75kgs and it took a two handed left to put her on the hitch.
It all depends on the boat and trailer set-up - my little box trailer has a hitch weight of about 20kgs and it tows not problem, but then the whole trailer even fully loaded is never over 200kgs...
The heavier the trailer the more weight is needed on the nose to balance it up - I think....
It also depends on the towing vehicle too, heavier it is, more it can 'ullies' the trailer.
When I was towing Sweet Honey with the Passat, it gets uncomfortable at around 60mph, but once I switched it to the Toyota, it towed easily at 70.
