    3870 crash bulkhead?

    Does anyone know if the 3870 bow crash bulkhead area a void or foam filled?
    Has anyone accessed this area?

    Pat,
    On mine it is just a void, no foam. I opened mine up to investigate if there was room to install a bow thruster, but felt it was too tight.

    It it did give me an opportunity to vacuum out the construction debris

      I am thinking about installing a Garmin transom mount transducer at a 45 deg angle fwd. in that bow space.
      I will epoxy it in, my Garmin 7612xsv has 2 ports for transducers a 12 pin and an 8 pin , I have 3 down transducers of 3 different freq. that I can switch back and forth, 2 12 pins and an 8 pin, screen will show 2 at a time.

            As I understand it, most crash bulkheads in Baylinersmine, including mine, do not have foam so it doesn’t effect th dynamics of the areas intended purpose. I’m curious what transducer you were thinking about installing up front. Is it a forward view? I installed mine (forward view transducer) about a 1/4 of the way from the bow, just past where it levels off along the keel... it works great!

              I was thinking I would use a Garmin transducer used as a transom mount and put it far enough to achieve a 45 deg angle forward.
              Garmin's forward looking transducers are rather expensive, such as the pantopix.
              I have a Garmin 12 pin GP51, a 41, and an 8 pin 30, the 2 12 pins I switch depending on what I want to search.
              I bought the Garmin fairings for those 3 and will install them as a thru-hulls this spring.
              I removed the 2 1000 watt bronze transducers a 50kz and a 200 kz which I will sell on ebay with new fairings.

                Garmin is pretty proud of thier thruhull panoptix, but, they are really nice,,, I have had the downview/sideview installed for a while. The CHIRP technology works well. I installed the forwardview thruhull a few months ago and love it, as well...

                  Pat, please describe exactly what you mean “ the crash bulkhead area”.

                    It is that area under the anchor locker in the bow, usually a sealed compartment in case you crash into a rock.

                        Hi Pat,

                        The area directly under the anchor locker is a separate chamber, I suspect very small. The area aft of that space is a bit larger and terminates at the plywood bulkhead forward of the compartment under the floor under the master berth. On my 38, the A/C unit sits on the top of that space. I've attached pictures to give you some idea of the space.

                          Thanks for the photo's, I will try and find the appropriate Garmin transducer to mount there at a bit less than 45 deg down, this will give me warning for fish targets prior to being over them.
                          I have 2 large bronze transducer foe sale, one is 1000 watts and the other 1200 watts, all bronze with cables, a 200 KZ and a 50 kz and fairings.
                          I need to find someone that would like to buy a Furuno 360 deg scanning sonar, with a 6" fiberglass tube for the dome and hoist with the display and a level motion sensor for correcting list and fore and aft.
                          A mid 90's unit with low time, I used it on my commercial boat, I will cut out the tube and patch the 6" hole in the bottom.
