GTA Online Yachts

In GTA Online there were three yachts.
You can buy them at the boat selling webside.
All Yachts have a airdefensesystem which have to be manually activated. You will find too weapons what you can pickup.
Additonal they have 3 Bedrooms a own bar, a landingzone for a helicopter. Unfortunately the yacht can not be driven manually. Just the captain can jump with the yacht from boat slip to boat slip what cost 25k per jump. The advantage of the yachts are they can used as spawn point. 
 

The Yachts cost between 6'000'000 - 10'000'000 GTA$, i would just recommend  to buy if you have alot money or love yachts as they have so much use.
Every Yacht has boast what were delivered with the yacht. Notice this vehicles can not be requested by pegasus.
To request them you have to buy them addionaly.

Yacht Conclusion

The Orion is the cheapest yacht, as there isn't a helicopter it is not same usfull like the other ones as an mobile spawn point. What you get for the price is the badest rate as just 100k go in other vehicles.
The Pisces ist the middle edition and is good if you need the "cheap" spawn point with a helicopter.
The best performence for the price give the Aquarius yacht.
