chartering insurance questions

[capnjack.morton]

For most of my life I've been paid to run other folks' boats and programs. I'm now chartering a boat for a week to take some in-laws sailing, and having my eyes opened. Charterer wants $95/day to cover a deductible damage waiver. That strikes me as steep, but what seems the worst of it is that it doesn't cover anything beyond hull & deck, (liability is separate at another $20/day) so that any damage belowdecks, mechanical systems, etc seems to be my responsibility up to about $5K, and the insurance specifically excludes anything they would consider "flagrant disregard for the standards of seamanship", which could include hitting rocks they've marked on the chart, or operating at night or in poor visibility. I haven't grounded a boat in 20 years, and don't expect to this time out, but isn't that part of what insurance is for?
Is this pretty much standard in the bareboat chartering policies?

I don't know if it's standard, but 5K sounds about right as a Deductable on a 350K boat so would seem fair enough. The waiver sounds like a typical waiver similar to rental cars or normal hull policies, although I think my deductible waiver is only $400/year so they're probably making a bit on the side there. They also probably make quite a bit by taking the 5K and doing repairs themselves for much less in most cases. Some Visa cards have a policy for hire cars where they pay the deductible in the event of a claim. I wonder if some cover charter boats as well?
