no nothing about it, I do know that some guys have tightebned the fit by applying a strip of some type of vinyl between the bottom of the sliding hatch and the groove it runs in on the deck. The only leaking I had on my V20's was thru a screw hole that was not caulked right opn top for the wood trim and the groove Blue told you about.

Willy - what do you know about improving the bow slider on a V21 to keep the water out ?
