This is a difficult question in the Jet Ski industry atm.
We have our Skis with Swann but have found some issues with their policies lately so will probably move them next time their due.
We went with them mostly as they have agreed value which is extremely important with Jet Skis.
We advise people to avoid SPT as there have been countless people find out that their policy isn't what they believed it to be mainly around higher premiums each year and yet a declining Ski value. SPT go by market value.
So we have a market where many newcomers have come in over the last few years, found out its not an easy market to play in and are now jacking up premiums or narrowing their policies.
I have heard a few good things about the new players like Youi but haven't worked with them.
The one that stands out in the shop is Club Marine and I'll probably move my Skis there. We have put through many claims for people and the customers are always very happy with them. I think this speaks for itself.
I hope that helps. Maybe others have experience to share?
