Lagoon 400 weight


 

Recently I have asked lift operator to check boat weight and it was 17,000 kg. I thought my boat is lightly loaded with around 2-3 T above light weight. If that is true, empty boat weights around 14-15T which is way way beyond factory published 10,350kg.

As this is over max allowed boat weight = 15 T, I am bit worried.?

On the other side boat feels quite performant and in recent rally outdone many glorified brands without any pushing. Also does not feel overloaded or slamming, etc.?

What are other people experiences with boat weight ?


 

Last time we were on scales it showed 14.4t.
With full water and fuel tanks.
We have genset that adds weight.

something has to be off. maybe the lift scale. if the light load is 7k kg less than what you are at, which is supposed to be with all tanks half full, and you have 7 tons of extra weight, don't see how your boat would perform...


 

To make things clear, and to ensure we are in safe limits, and my background is physicist, I have calculated boat weight using archimede law, meaning boat weights as much as displaced water. Got 12.8 T, using some hull shape approximations and excel and measurements of hull immersion in totally flat water. We travel light and have not too many gadgets. Boat performs quite well compared to other cat brands.?

So, that lift must have been way off, as calculation error is less than 1 T.?

I can now get pretty exact weight any time using only hull immersion measurement .


 

My L400 just off hard lifter was brand new so I assume weight accurate mine is loaded weighed in at 12000 kg.
