Needs to be on your driveway inside the legal boundary.  Had this issue with another wrecky with RAC where it was half on half off, they tried to deny the claim but their own policy cover picture actually shows a boat in exactly that position......they backed down and paid.

I use Trident but they are not the cheapest.

 I also use Trident Insurance, who have recently had a name change to Coast Insurance. Found them to be excellent so far.

 I have used them for years but touch wood no claim so can't answer if any good. I guess the same as most insurers, try to get out of paying a claim where possible!!!

I also use Club Marine, tried to make a claim once where a few things where stolen from my boat while on my property

They refused to pay and said I should go through my home and contents insurer (RAC)

RAC refused to pay saying that it should be the boat insurer who pays, so got nothing in the end.

A necessary evil that you can't be without and yet they still come up with excuses to stick it up you.

 I use club marine

Made 1 claim with them when my sounder and fishing gear was stolen out of my locked cabin. Really easy to deal with and no real questions asked. Got everything replaced within about 2 weeks

Cheers

I recently had a claim with them for a killed motor and it was a hassle free process. It pays to shop around and avoid the so called " Marine expert " insurers. 

Thanks all. I have gone with Coast Insurance. In the end it was either Coast or Club, I didnt check Elders but did check a few other big name insurance companies and they wouldnt insure the particular scenarios I wanted or needed to pay extra for it.  They were also the most cost effective for my needs. 

Only ever made one claim and that was with Club Marine, was a bloody nightmare as they used every conceivable excuse to not payout on certain items.
One piece of advice I can give is that if you have a decent sized boat that runs a fair amount of boating equipment is to take note of what you have and photograph everything as they will ask for photo's if they have been stolen.
Any fishing gear, rods, reels & tackle not contained with a lockable cabin is not covered so don't pre pack for a fishing trip the night before.
When they ask questions do not give too much detail as they will find any excuse to bring up t&c's, keep it minimal, they are not there for you when things go wrong other than too reduce the claim payout at their end.
Fortunately for me I have two rottweilers that left quite a long blood trail over the backyard garden and fence, the blood was from neither of the two rotties so justice was served in my opinion.
