Noel - Avemco did provide me with the required coverage and a
separate binder page for presenting at SSA contests. I've been
very happy with their service for many years and insure a
number of aircraft with them...
Perhaps you should give them another call ?

Dave -

Sent you a private email. Would love to know who at Avemco you worked
with on this... I've talked to several people and it seems that inside
Avemco there may be different understandings of what they can and
can't do.

I'm also looking at a couple of other carriers as possibilities.

To address some of the comments by others: I'm not trying to trash
Costello. But I found that Avemco gave me more flexible payment
options, could cover both my glider and the Experimental Sonex kit-
plane that I'm building, and my premiums were the same or slightly
less than with Costello. I am loathe to give up the payment
flexibility and deal with multiple insurance carriers for my 2
aircraft (OK, one is still mostly parts in my garage; but I'm still
required to insure it).

Lastly: Anyone who thinks that an insurance policy protects them from
being sued in an accident is ludicrous. In the US, if someone thinks
they can sue you and get more money, they will. I also don't see how
higher coverage will somehow indemnify the SSA from being sued as a
party to the contest (if the argument is that we need higher coverage
at sanctioned contests to "protect" the SSA)...
