I'm under contract to buy a 2011 Azimut 58...

I didn't open the attachment. But your next move should be obvious. Submit in writing a request for extension of dates to suit your requirements. Give the seller 48 hours to respond. If they accept your modified dates, fine. If they don't, then it's your decision to move forward with the original terms or not. But it looks like you may have already talked yourself out of it now anyway.

You need more than 5 minutes at speed to make sure no issues pop up. You want to be sure both coolant and gear temps stabilize.

I m expert on the river system but spring is usually subject to high flows and food due to melting. Expect delays which will rack up the delivery costs. Lots of debris too which can cause running gear damage

She does look well equipped indeed.
Btw, it seems from the engines pics that there are PTO hydraulic pumps on both sides.
Out of curiousity, do you possibly know why?
I don't think the Seakeeper needs that, and I'd be surprised if the thrusters were hydraulic.

Okay so you wrote up an extension request and it was denied then. Asking is not the same as submitting the request in writing. Asking is deflected by sellers easily and most often. Closing on time seems near impossible based on your posting further details - if you want to be involved personally. Either way good luck in your endeavor.

Well I don’t want to beat a dead horse at this point but I am going to take one last swing here because this is a pet peeve of mine. It’s not the brokers decision. That’s always the answer when you ask the sellers agent. That’s why I always put it in writing and that gets put in front of the seller. Anyway, I’m sure you’ll figure out your way through it.

The seller doesn’t have to do anything that’s not in the contract. I would have a contract that I can live with before I spend money inspecting the boat. What you ask for at the end, survey allowance, closing date extension, etc you are going to have to live with the sellers response. Sometimes things go smoothly sometimes there’s bad feelings by closing time. The less you need from the seller before closing the less of your time you may be wasting.

If you don’t inspect, do a sea trial and survey before the 17th you will have to accept the vessel and close on the 31st or loose your deposit

If weather prevent sea trial, you may be able to get out of the contract... better have an attorney look into it.
You need to get up there with a surveyor ASAP...

how could anyone sign a contract with tight deadlines sight unseen in the middle of winter !!!!

In the seller and broker's boots, I would already consider yourself very serious indeed, for 68 thousands of good reasons...

As a premise, I have nothing to see with Azimut, and the fact that Vitelli is a compatriot of mine is where my relationship with him ends.
Besides, I did consider a few of their boats in the past, and I liked none of them, for reasons irrelevant in this context but which have nothing to see with their electrical systems.
Not because I'd call them excellent, but because I've seen much worse - also in some US boats, btw.

All that said, it seems to me that yours is a sweeping generalization.
There aren't many boatbuilders who survived the worst crisis in the history of pleasure boat industry without going bankrupt or resorting to some turnaround specialist (AKA buzzards), and eventually came out even stronger than before.
If you can think of anyone else who performed better than Azimut Group in this respect, I'm curious to hear what names spring to your mind, because pretty sure there is none on this side of the Pond.
This doesn't mean that their products are the be-all and end-all of the yachting world, of course.
But if they managed to do what they did by building and selling "problem childs", one should wonder what all their competitors were thinking...?!?

I don’t consider surviving a recession a reason to buy a boat from a builder.

that said I ll five two names. Hatteras and Viking. The new viking MY are pretty impressive and top quality. Hatteras well... no need to explain.
