One of the disadvantages of an electric boatlift can be that the height at which it is raised blocks your view of the water and beyond. There is also the lost convenience of just stepping or climbing aboard your boat when it is kept in the water.
But considering how often recreational boat owners use their craft the lowering of the boatlift into the water is a small effort, while the peace of mind of having it out of the water the rest of the time is worth the trade-off.
A boatlift gets your boat off the water and eliminates the problem of chafing wear to dock lines and fairleads. It also prevents constant bumping into a dock from wind, waves and boat wake.
By not leaving your precious boat in the water, a boatlift allows you to forego anti-fouling – an expensive and recurring job.
