My bilge hoses are all that ribbed stuff. Not only does it hold water but it is almost impossible to clean. I assume all you Cherubini owners have the same stuff. Have any of you replaced it with regular hose? I found one in the archives(Related Link). Is this a good idea? Somewhat related is the manual bilge hose. I took that panel off the rear of the quarterberth to gain access under the winch for some wiring work. There is an extra four feet of that hose rolled up back there. Is there a reason for this? Or is this because that was how much hose there was before the next flat connector spot? Thanx for your insight.
