Post Subject: weed hatch

we have just purchased a second hand canal boat and on inspection of the weed hatch there isnt a baffle plate, i could easily make one, my question is what are the benefits of having it and how far down the weed hatch would it need to be placed.

Not all narrowboats have a baffle plate. When they are fitted they are supposed to help reduce hydrophonic noise, help combat cavitation, and help prevent eddies building up as these make the water flow to the prop turbulent and less effective. If you are going to fit one try to get it about level with the bottom of the wee hatch trunk so it is in line with the uxter (swim) plate. As long as the boat handles well without excess noise I would do absolutely nothing. Leave it as it is.

PS, if you do fit one make sure it is absolutely stiff. The baffle plate can vibrate on the side of the trunk and make horrible noises.
