General Info: L450 Window leaks

[DavefromNZ]

For the record after clearing out the sealant for about 40cm around each window's front corner it looks like they were never really attached just filled with sealant. The rest of the windows along the side seem secure. For now we have resealed and will have them removed and fully glued in. However I suspect that the shape won't match the curve so it may not be very easy.

We are covered under warrantee and the guy from Lagoon HQ had heard of the problem before, hmmm.

We have been in some serious weather conditions and our cat has been out crossing oceans for the last 2 years and no issues like this. However, I would MOST DEFINITELY make this a LAGOON DEALER ISSUE ... you may have to fight them for it but they will have to do that repair. I would think it is an adhesive bonding problem unless the boat was 'dropped' at an angle from its slings or some other reason which placed undue 'flexing distortion' on the frame? Best bet if you are having hassles with the dealers is to fly to a boat show where the dealer is and have it out with them in person ... I found I got the best results that way!

Oh ... by the way ... spoke to someone who had this issue on a 500. Windows kept 'popping' ... the 500 eventually was discovered to have separating bulk heads ... a production issue on the initial 500's due to a new manufacturing process. I am not saying there are issues like this with the L450's but best keep that in mind as one never knows what structural issues could contribute to windows 'separating' ...

By the way Dave ... the fact that the guy from Lagoon HQ admits he has heard of the problem before ... is a good thing! They used to try tell me my issues 'were unheard of' ... until we started raising it on the forum etc.

All boats have 'teething problems' and the L450 is a new design so there will be some initial issues. My dealers had told me at the time, that they as dealers get a commission which includes warranty repairs to be done at the dealers cost within that commission. They were squealing because I was photographing and documenting every issue in writing that needed repair and they had 'exceeded that budget'.
In the US (at the Miami Boat Show) I took this up with the representatives from Lagoon HQ's and they denied it, so one never knows where one is with these things.

In the end my 'soft side' kicked in and I just appointed specialist marine experts to come onboard and 'perfect the boat' at my cost. The 'warranty claim' I would have insisted on ... around US$ 30K.

Take photo's and keep well documented records ... who you spoke to when and so on. Lagoons policy seems to be ... 'we are correct until you PROVE us wrong'.

Still ... they make SUPER boats ... and thats according to most cruisers who have been onboard ours from all over the world, so don't be disheartened ... but be prepared to dig into the pockets to get it to where you want it to be.

My feeling is that a second hand well maintained Lagoon should fetch more money than a new one out of the factory ... knowing what I now know

Hi Impi. Yes it seems Lagoon/dealer have admitted the problem and it will be covered under warrantee. I have had a number of other minor issues and been over our L450 from top to bottom fixing stuff and making improvements as we all do.

To give an example of the level of Lagoon back up service; I had a problem with slosh in the bilge causing the Rule 2000 to start but it would continue to run unless I pushed on and off the switch on the flybridge. After back and forward email question from Lagoon technical section their final answer was and I quote "Yes the Lagoon 450 has both an automatic and manual bilge pump". Thanks for nothing!

PS I replaced the float switches as they had failed and the buzzers as they were also failing.

PPS I still love the L450 it is simply a wonderful yacht and we have had some great times with many friends who are all astounded how big the living spaces are! I am off around NZ in Jan and Feb

We have the same issue on the 440 ... not on the automatic bildge pump which is the smaller of the two (per hull) which engages the alarm, but on the bigger manual bildge pumps. If we have the switches toggled the wrong way on the bridge, then they do not come on when switched on below ... quite frustrating really.

Had bilge pump problems on both my L450s. On the first the pumps did not come on after about 6 weeks. Changed them to the float type switches. On this one they do not turn off after they started the pumps. Float-type switches are in the "mail" from Lagoon.

I have a Lagoon 470 that had the same issue. The windows had to come out to put new caulk in. However the problem turned out to be that there was only one layer of glass mat where the the vertical turns to the horizontal and it cracked. So the windows came out and fresh glass mat and resin was put in to strengthen the join before the windows went back in. The problem was on both sides. Didn't really notice until we got into sustained bad weather followed by an area where it rains inches at at a time.

If you are having this done under warranty, I would insist on the windows coming out and then inspect the fiberglass (and spray it and look for leaks).

That is a strong perception, as it reflects Lagoon's lack of quality control. Lagoon boats are surely engineering marvels, but it is incredible that as I read the forums, newer boats do have the most reported issues. Is quality going down or older boat owners have already fixed it?

What I have yet to fathom is why those switches are on the flybridge! What is the point? I can't know that I need to use them from the flybridge, and like you, I have to have both the internal switch on AND the flybridge switch on for them to work.
