We tried it, didn't work for us, petty issues can get blown out of all proportion.
I thought it would be good for us as we both work, and to a point it did. Decided to sell our shares (easier said than done) and buy our own boat. That was ten years ago and the restoration took 5 years and a lot of hard earned, we still don't get as much time as we would like as we still work to pay for it.
Boat owning or syndicate owner, both need compromises, we have tried both and know which we prefer.
On the positive front the cost per night is now coming down after 5 years afloat, I reckon about £500.00 a night !
