That will never do!
That's the scariest thing about flying out to a ship that already has a helo aboard ...supposedly..and you get there and you don't see the other helo.....WHERE THE F IS IT?????? you scream over the intercom worried that it's pilot may not see you and is about to collide with you!!!!

Naw....never happened to me....

Re: Helicopters and Motor Yachts

Running a helicopter is expensive. Perhaps some tips here may help :

Shoestring Sailors (Cruising on $500 per month - part II)

Figure about a boat buck an hour for a newer small turbine, more if it's not nearly new, this is of course for one fully paid for.

Re: Helicopters and Motor Yachts

This reminds me...

A former shipmate on my sub was a former DSRV pilot, and a really heavy drinker. He was out at the bars every night we were in port, he even had a $20 bill and directions where to tell the cabby to dump him if found on the curb. One night he ended up sitting in a bar next to a couple of helicopter pilots who were trying to impress the waitress with their daring exploits.

After witnessing all he could stand of their foolishness, he announced that he was a DSRV pilot, and these 2 clowns didn't look like any helicopter pilots he had ever seen. When one of them asked, "What does a helicopter pilot look like?"

He slumped forward in his chair, feigning death.

According to him, they quietly paid their tab and left.

I always believe stories from REALLY heavy drinkers..

especially one that really don't make much sense....

What doesn't make sense? Helicopters crash into the sea all of the time. As a DSRV pilot, the only ones he ever saw were the ones he had to retrieve, dead ones.

Or are you having a hard time believing they left the bar quietly?

OK ....I get itnow...

...and no old-timer helo pilot ever left any place quietly...we are all hard of hearing...

Hmmm.
Not as difficult as you might think to do this.

However, quality fit out, even without all the glitz, is still not cheap!

So identifying the right Yard, at the right time in their management evolution, is easier if you provide all the engineering details I discussed in a Feasibility Study…..

For this allows you to compare apples with apples in assessing each Builder’s ability to execute.
(I was often told that our Bid package provided them with more engineering info than they had on super yachts they were actually building)

To achieve this feasibility detail, you just need to put together the right team of qualified consultants and keep them outside the bid process so that there is no collusion between them and the Builder during negotiations. (I even took myself out of handling communications until we had shortlisted the Bid Replies)

For major decisions …you start with the key requests by the Owner that will drive the design decisions:

For example if quietness underway is a key element where you want to achieve NOISE TARGETS of 40-45db just forward on the engine room at 12 knots, then you cannot cost effectively achieve that with a commercial conversions.
(It is like trying to provide a quiet Bentley ride by converting a dump truck)
http://www.audiology.org/practice/re...Chart16x20.pdf

To achieve 42dba levels as above, it means floating floors and bulkheads, structural design to reduce harmonics and a layout that will diffuse propeller pulses.
So that rules out a commercial conversion and you focus on a new hull, which gives you a clean slate of many more options.

To be a good Owner’s Rep/Build Captain… You need to have achieved the practical experience at sea in command to garner team respect to help guide them towards cost effective solutions.

Often that means compromises
Since solutions need to look after the often disparate needs of:
The 4 Crew Departments/ the Owner-Owner’s Wife/ Builder’s Standard of Execution and quite often Designer’s Egos.

It can be a fun process and if done right, the actual building phase is pretty anticlimactic and you have a much better chance of giving both the Owners and Crew, with what they want at a better price.

Re: Helicopters and Motor Yachts

What about getting a Dynamic position class 3 DSV with pre installed helipad.

In the USCG we did full engine idle instrument only autos to the water under the instrument hood....we all learned to slide them on like sliding on glass...even in several foot seas.
The effectiveness of the whole auto-rotate thing kind of depends on how much altitude you have when things stop going your way...no? Under ideal practice conditions, you may get ideal results. Under conditions where an auto-rotate becomes a matter of necessity, your options, & therefore your results, may be less palatable...no?

Last I checked, a little R-22 (Hyundai of the sky for rotor-craft) was about $150/hour wet, after you amortized in your maintenance costs. That was several years ago.

I'm a little out of date on this stuff. It sounds like improvements may have been made since my last harrowing experience in a H-269-A

No...helo pilot's know it's several factors that will add or detract from a successful auto.

Like all landing and flying in general...the quality of the pilot and his/her training is a big part....also followed by fitness and attitude to fly.

Always stay in the safe autorotative envelope and it's no big deal if you are well trained...

If this guy has the money...he'll buy twin engines.

Re: Helicopters and Motor Yachts

Some twins have 'fly-away' capability; some don't. 'Fly-away' means exactly as it sounds if the a/c experiences an engine failure in a critical period of flight, usually just after take off. The Heliport & Helideck standards differ significantly depending on the 'design helicopter' and whether it has 'fly-away' capability.

Helicopters are very expensive. Twins far more so. Those with 'fly-away' are rarely owned & operated privately due to their extreme expense.
