      The 424 isn’t a light boat by today’s standard and doesn’t need more ballast. Still, I don’t like having the deep sump. Concrete comes in various forms including some mixes that use plastic for aggregate. I contacted someone a couple of years back that makes various products including at least one mix that even floats. He uses polystyrene instead of stone. This process is apparently common in Europe. I believe he was in Arizona. He was unwilling to ship a small volume to New Hampshire however. I’d be reluctant to fill my sump with a few hundred pounds of concrete, but the lightweight plastic stuff might be different.

      Rich,

      What is it you don’t like about a deep sump?

      I’ll respond- I hate the standing water from front to back in the deep bilge.Sure,it’s only an inch or two,but to me,too much.I’d much prefer to have 3-6 inches of concrete sloped toward the front and then a small 2 by 2 ft sump with about 1-2 inches of water.I have many times thought of adding the concrete.My previous 42 ft boat had a 2 by 2 sump-it was very easy to keep clean.You also know right away if you have a leak.
      I am about to install a small bilge that will empty most of the standing water.I have a larger pump for real needs.
      I’d add the concrete but I’m afraid it may cause other problems and or breakup overtime if it isn’t done right.  Have you ever seen another boat with such a deep,long canal of water?It’s my only complaint.I’m with Rich-find me a light ,durable,easy to apply filler.

      Paul, the only concern I'd have with the product in there is what if water gets between the filler and the bilge wall in the winter and freezes. 
       
      I like the deep keel.  In a messy seaway I know I'm going to gather some water on board.  With it waaaaaay down in that well I also know that it will stay in that general area until pumped out.  Much better than possibly slopping around under the floorboards. 
       
      A breaking wave over the stern at the wrong time could find you with 100+ gallons of water added to your list of provisions.  That big bathtub at the back of the keel is a real sweet place for it to end up for its short visit aboard.

      I'm sure I've seen threads about this in the past, but could find them.
       
      I looked at a P424 this weekend with a “filled in sump”. It appears to be concrete. I'm not sure what this might do to structural integrity (better? worse?) or how the added weight might ultimately affect the performance.
       
      I'd love to get input from others, particularly from anyone who's actually done this to their boat.
       
      Please lemme know. Thanks,

      Paul

      Impossible to clean. There’s odd tools and lost parts down there, never to be seen again. I’m too big to fit down there and I’m not persuasive enough to talk anyone into cleaning it for me.

      Rich,

      I suspect the skipper’s body size is often a decisive criterion when judging the 424’s sump. I can (just barely) fit myself into the forward end of that space, scrunched down at an awkward angle on one knee, and can reach the after end of it with a handled brush. One of the first things I did when I bought my boat was to scrub, flush and re-scrub the entire space clean and then paint it bright white. To this day is remains clean, fresh, white and bone dry but for a half-inch of clear water that the pumps can’t get. If I ever do have a lot of seawater come into the boat, that’s where I want it contained until the pumps can deal with it.

      Even if I couldn’t get myself down there at all, I’d still endeavor to keep it clean with a long-handled brush.

      Funny that this subject would come up today. I just surveyed a 424 in Anacortes that has its bilge filled with concrete. The overall job was nice and it did eliminate the deep bilge and clean up would be a snap. This arrangement should also eliminate the weak after bilge area. The vessel seemed to sit on the water nicely and motored nicely. I did not get to sail her however (she is sloop rigged so it may be like comparing apples to oranges to my ketch). I have never been in love with the deep bilge but have got used to dragging my shop vac down twice a year to vacuum her bilges out.

      I don’t know if I would drop a ton of ready-mix into Syringa’s bilge. But I have been considering foaming the bilge and glassing over the top.

      Also I would like to report that the vessel had a bow thruster and a Max-prop. She could turn on a dime and only had a slight pull when at full engine RPM (HOW NICE!)

      That must be Rhythm with the stainless toe rail, no?

      Yes (I would kill for the stainless cap rails)

      I flush the bilge with water and then empty out a shop vac to start with a clean container. Most things in the bottom of the bilge will come up with the vac. Then it’s just culling out what needs to be washed off.

      I have a shower sump pan glassed in forward of the V-drive pan. this obstructs access to the aft section of the bilge sump which is very narrow anyway. There’s a bunch of hoses down there that add more obstructions. I never liked the shower sump pan. Its just a place for hair and other stuff to collect. I’m thinking of removing it this spring. That might open it up for cleaning a little more. I might use a power washer down there. That would clean it up nicely.

      Regards
      Rich

      Hi Rich, 

      I took that crappy sump out – if it's the one that Pearson made.  I installed a strainer between the drain and the sump pump.  I can live with an inch of water in the shower until I activate the pump.  The Pearson sump was less than useful anyway and blocked the bilge.

      When I put in my holding tank, I needed access to the bilge pumps and other stuff, so out it went!

      other good things to have to rescue items from the bilge:

      Magnet on a stick

      Grabby tool
      http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=94162
      This is just an example and it only has two prongs. I have one with three works great for screws.
