I’ve used both a boat buddy II and ramp n clamp but prefer the ramp n clamp, tougher material and better design. As long as the trailer is in the right position/level in the ramp I thinks it is the fastest way to recover/load a boat. I suspect the drotto is the same way. Almost gone are the days of me walking the boat onto the trailer or standing in the water / on the front of the trailer cranking on a winch. I prefer to launch and recover as quickly as possible.
I have a two speed winch as well but rarely use it to recover my boat and only use the second gear once a year or so just to confirm it still engages.
The drotto looks like it adds a large release lever to to the assembly which can be used from the bow of the boat. I don’t see any reason the ramp n clamp cannot be used the same way, it wouldn’t take much to add an extension to the engage/release lever, not true of the boat buddy because of the way it is designed. That is not a feature I need but if ever replace my ramp n clamp the drotto would be on my short list.
If you never have one of these devices you will never have a problem using one but you will also never know what your missing.
