Tiara 4000 e related Swim platform carrying capacity

[nukey99]

I didn't see a 4000 forum, so posted here as the Sovran seems to be the next generation of the 4000E.

My family and I are considering various tender type of things.  One option is a very lightweight jetski, the Sea Doo Spark, which in a 3 up rider version weighs in at 421 lbs dry.  

Are there any 4000e owners out there carrying such a load on the swim platform?  Also, if you are, I would love to see what your davit arraignment is.

Your input is eagerly anticipated and appreciated.

thanks

Jim
