    The trick for me was to find the streaks, sometimes just shiny trails, of where the water was coming from then trace it back. Sometimes the trail goes cold though as it leads to areas you can't see beyond!

    A little OCD kicking-in, I guess!

    Would anyone happen to know the rough dimensions of the front windows on the 42/44 DB. Want to pick up some sun blackout shades from Amazon (more for privacy) but won't be at the boat until this weekend.

    Thanks

    Sorry, I did not see this earlier as I was at the boat. I actually made some foil laminated bubble wrap insulation screens that I put under my sunbrella black out windshield cover. I made an entire set for the cabin that just wedge in the window frames between the window and the shades. Virtually no UV penetrates the cabin. I install them when we are not on the boat and some times put the shades up on particularly hot sunny days on the sun side. I cut them to shape and then sewed a binding to the edges. I found the paper templates for the side cabin windows but I don't know what I did with the front window templates.

    The outside two windows are 42” wide(side to side) and 38” long(top to bottom). The center window is 40” wide and 44” long. This is pretty close. If you want exact, let me know.

    I have a new to me 07 44 DB that has major water leaks into the bilge during hard rains which happens every day in Florida. I was on the boat during a storm the other day and found water to be flowing down the hull sides near the water heater on one side and the holding tank on the other. I was thinking there could be a problem in the engine vents or the joint between the hull and deck is leaking. I have repaired the drains to the rod holders.
    Has anyone had this problem?

    Thanks

    You might remove and reseal the engine vent moldings. The PO or their detailer may have removed them for polishing and then reinstalled without sealing them.
    Happy hunting and enjoy your 44, we love ours

    Thanks for the reply. That was going to be my first place to look but I think the leak is aft by a foot or two.

    I did this about 10 years ago, cut the vent line behind the generator panel and added another filter. This one I can get to, the one on top of the holding tank is out of reach for me. This setup has worked for me for 10 years already!

    I have hard panels (Polycarbonate) all around. The center fr0n and back panels snap to the ceiling. The center side panels are hinged and can open half or full, also attached by snaps!

    Based on my experience, the spillage from the vents happens only when topping off the tanks by allowing a pump's nuzzle to shut off automatically. Some aren't tuned and spillage happens at the fill. To avoid this, I just listen as the tanks are getting close to full and I manually stop the pump as soon as I hear the change in the sound pitch, indicating that the tanks are getting full. Having said that, I spill the fuel via vents on very rare occasion.

    I agree with you Alex. The fuel gets stuck in the vent line only when the tank is overfilled. However, sometimes an inexperienced pump operator, or background noise make it difficult to hear when the tanks are nearing full. I usually monitor the fuel gauges at the helm and have them slow down when the gauge says we're close. Usually once a season I'll get overfilled, and then the vent lines will spit drops of fuel for several fill ups going forward.

    Good to know, fueled up a few days ago and there was no spillage when we started. Will try this method and see how it goes.

    I don’t fit back there anymore, but my toilet repair guy removed the pump and repaired the pump which turned out to be just the duck bills on the dock!

    I discovered this in year one after taking delivery. The dealer installed a check valve in each drain hose, problem solved!

    Any idea what type of check valve was used?
