Good evening everyone, I've been lurking on the forum for a while but this is my first post. I finally taken the plunge and taken delivery of a Hanse 348 (having been lusting after one for years  )I'm looking to install a stereo in the saloon as one of my first projects. I've found the location pre-routed cut outs for both the stereo head unit and the port-side speaker. I can see from the stock photos that the starboard side speaker is on the end of the locker at the outboard end of the galley unit, facing forward. However I can't seem to find out how that panel is secured and more importantly how to access it so that I see where the pre-cut is. Can anyone guide me to either a technical drawing of where the cut out is, or preferable tell me how to remove that panel? On that note, any hints on how to detach the panel on which the VHF is mounted from within the locker. Any clues would be most gratefully received. Thanks in advance

Here’s something to try. Some of the vertical flat wooden panels on my boat are held on by clips, such as the panels that cover the holding tanks in the heads. These panels can be removed by using the suction cup provided with your boat. Attach the cup to the panel and start pulling it away from the wall. The clips are usually one on each side midway from top to bottom. Just try and see if if you can feel any give as you try and pull the panel back. If it has the clips, you will start to hear them work free as the panel starts to come away. Sorry I don’t have any pictures. Don’t know what your particular setup is on the 348 but my VHF panel is just attached with four screws on the corners. Good luck. ------------- Mike S/V Dulces Sueños 458 #087 Tampa, FL |

Hi Mike - thanks for your responses. I'll be back onboard this weekend so will let you know how I get on. Hopefully with some photos to illustrate success (or failure  )Really appreciate you taking an interest Best wishes Andrew

A couple of Sonos powered speakers and an iPhone will give you great sound. Just a thought!! Duncan

Hi All - follow up as promised. Firstly
thanks to Mike for the suggestion to use the plunger. Whilst that
didn't work for the starboard panels for the speaker, it certainly did
for the panel that houses the VHF and (eventually) the stereo. That's
solved half my problem. OK - to return to the starboard speaker position  I've seen the Hanse Stock photos show a speaker install in the panel marked with the blue arrow. This is covered in a type of fabric so the plunger for panel removal doesn't hold vacuum to allow its removal that way. It seems really secure there. Similarly the panel marked with a red arrow is equally secure (and has a trim strip from the galley in front of it). The magic question is therefore - how do I get into the space behind the blue arrow panel to see whether there are any pre-machined speaker positions (as there are on the port side locker) Thanks again for everyone's interest. PS - Thanks for the comment about Sonos Duncan - we have those at home so I'm a convert to their systems already. However I already have the fusion radio and speakers (just need to get them installed ) |

You can try get to this space from the bottom. Even if there might be a wood panel there you can drill some access hole to let the wires in. Nobody will be able to see it anyway

Maybe the panel above the red arrow panel comes off? ------------- Mike S/V Dulces Sueños 458 #087 Tampa, FL |

Dear All - @marsella, sadly the panel above the red arrowed one is fixed solid too @Mike As for access from underneath, I did have a look. In the space immediately behind the seatback cushion there is one of the bits of battery charging kit (completely forget which one now - sorry. Drill up would be somewhat tricksy with this in the way but I'll have a dig around next time I'm onboard to see how easy this would be to temporarily move out of the way Thanks again everyone - really value your input

| You may not even need actual access to this void, decide where you want to hang your speaker and where exactly the wiring goes inside the void, drill a small hole for the wiring, then take endoscope camera, insert into the hole and see if you can pass the wiring thru the void to your desired location of your radio. |

Thanks Marsella - I've ordered a budget endoscope from Amazon to see if this work  ------------- Hanse 348 - Phase Shift |

Dear all, With the endoscope I was able to get up inside and see that the joinery had been fully routed out to take the speaker and then the fabric cover panel shown in my previous image as covering the space. This gave me the confidence to prise the fabric covered panel off and as can be seen from the image below this had simply been bonded in place with a cartridge gun adhesive Good news: Speaker aperture already cut for me Bad news: I now have a splodge load of Sikaflex to remove Thanks for all your interest and advice everyone  ------------- Hanse 348 - Phase Shift |

Wow! Spare no sika for the small fabric panel - wouldn’t want it to go flying off in heavy seas and mar something with that soft fabric🙄🤷♂️. ------------- Mike S/V Dulces Sueños 458 #087 Tampa, FL |

Thanks for that Mike. I had a similar thought but didn't express it anywhere as succinctly as that.

Quick follow up that may have useful info for you all. Removing the sikaflex in a manner that didn't trash the appearance of the panel in the photo above was always going to be a challenge. I used a brand new scalpel blade and was able to shift the bulk of the material above but this left a thin grey film on the surface. I tried most of the readily available options (IPA, meths, acectone) but not made a difference. However one solution did. There is an off-the-shelf solvent called DMSO (even Amazon has it) and it appears to be completely harmless - no hazard warnings at all. However it is indicated as causing cured PU to swell (albeit slowly). I mixed this up with some fumed silica to make a thick gel that would not slide off the vertical surface, applied it and waited .. and waited ... and waited ... After a few hours the gel and the remnants of the grey PU film could be scraped off with the edge of an old credit card and the surface looks unaffected at all. I meant to take some photos of the finished job, but completely forgot. I'll do so next time I'm on board. Hope this helps ------------- Hanse 348 - Phase Shift |
