The boat I was using was a 16 1/2 foot Lund Rebel with a 90 HP Mercury. The tailor was built for a larger boat, an 18 to 20 foot would fit no doubt, possibly 23 foot would likely fit.
Weight & height would be the restrictions for you to consider & they are dependant upon both the boat & tow vehicle.
The approximate empty weight for the trailer is approximately 3300 Lbs. The trailer is registered for a total weight of 13000 Lbs.
I do have pictures but the forum wont let me upload them as they are too big, if you let me know your email I can send them to you.
