I've had a parcel at Erik, (directly East of Arnthrud) for over 2 years and have enjoyed air/water access via Herkja.
After being rudely booted by the 5-second orb, at 270m altitude (where I took off from), I appealed via IM, to the rental management, to adust the timer to something more reasonable.
Typically, this request was ignored. I've heard from several others who were also ignored by the owner, who evidently doesn't care who he upsets, or inconveniences, with his growing rash of ubiquitous hearts.
5 seconds barely allows time for the "Oh, sh** !" reflex, nevermind take appropriate action and vacate the sim voluntarily.
I thought there was a decree that such devices must be set 10 seconds minimum? If not, pure commonsense should tell owners, that 5 seconds allows absolutely no action to be taken, by the detected party. Whatever your standpoint on the old Orb arguments, (from both sides), a more reasonable timing should be considered.
Although technically, there is a navigable route* from Loorq to Arnthrud, it isnt conveniently open to casual water traffic. Even if you make it through to Arnthrud, with Hekja blocked, that's the end of the line for many mariners. Arnthrud is now little more than an isolated lake.
Makes me wonder, now that Arnthrud is effectively cut off, how long it will be before LL decided to sell the water sim and consequently make the surrounding land virtually worthless.
In the more serious case of Rollo, I'm amazed the inconsiderate owner hasnt been admonished by Lindens, for preventing navigation along that solitary route from South to North. Affecting not just water traffic but aviation, too.
* There is a moveable bridge (click to raise) at Northern edge of Thorlaug sim, which is kindly kept navigable by the owner. That passage leads down into the group-only channel. (the owner of that water, is happy to accommodate boating traffic, providing users don't mind the minor inconvenience of joining her group). NE corner of Askold sim is passable, with public access, so technically it is possible for boats to pass into Arnthrud from the sea at Loorq.
