Can a PWC be hauled on top of 61' MY?

Can a PWC be hauled on top of a 61' MY?

I read Freestyle's earlier post on towing a PWC, but did not want to highjack his thread. For sometime we have wanted to buy a Honda PWC - dry weight just under 800 lbs - and rather than tow it, we wanted to haul it on top of our 61' MY, by placing it just aft of the 13' Boston Whaler
tender. That way we could manage it with the tender lift just as we do the tender.

Has anyone done this before? I think I recall seeing the arrangement in a photograph somewhere.

If we were to place it on the aft portion of the top of the boat, it would partially be located on
the top where it overhangs the small aft deck on the 61' MY--which is not supported from below.

My concerns are: (i) whether it will significanty affect the balance of the boat, and (ii) whether it will significantly stress the top of the boat where it overhangs the small aft deck? A photo of the top
of the boat and the overhang is below (ignore the workers--lol). Is it practical to consider doing this?

I would appreciate any thoughts or advice.

Thanks,

Paul

The new Hatt on my dock has a tender and a jet ski on top in that arrangement you describe, and its aft deck ceiling where the vessels sit, does have two large metal supports running from the lower deck up to support the deck above at the aft edge. This being a fairly new Hatt, I'm sure it's original.

There is a forum member who has a Series I 58MY like mine and he carries a helicoptor on his aft deck. All of this makes me wonder just how much weight these structures will actually handle.

Thanks. I did think about two stainless posts on either corner, but did not think it would look too good. I may end up doing that though.

If that area, however, will support a helicopter (nice!), perhaps I should have no real concern about it.

it's not going to be easy to add any post at the corners because of the curve of the hard top... not going to be very efficient. is the whole PWC going to be on the overhang or will part of it actaully sit over the bulkhead ? if so, you should be fine...

you can simulate the weight by having 4 or 5 adults stand there and see if there is any flexing...

or call hatteras, maybe they can give you some information, I woudn't be surprised if some owners have mounted the dinghy chocks further back than yours

I have a 61MY and the po had a PWC and a RIB on the boat deck. The PWC sat behind the RIB on a second set of chocks. The standard Marquipt davit handeled it.

I agree about the efficiency of the posts. The area is not suited well for the installation of supports from below.

The PWC will sort-of straddle the bulkhead, but over half of it will sit on the overhang. Thus, the overhang will bear considerable weight. I like the idea of getting 4 or 5 guys up there to see whether or the extent to which the deck flexes.

I have actually seen some boats where the dinghy chocks are further back than mine.

Thanks,
