All,
Head ruled heart in the end and I cancelled the viewing yesterday evening.
The reason being the maintenance costs. I know boating will always cost but with this particular boat I'd imagine I'd be having my pants pulled down a fair amount when it comes to structural work given its make up.
And the other worry was, as pointed out above, it's only just meets the insurance requirements as it is meaning I'd be forced into more work sooner rather than later.
Lastly, the stability issue mentioned worries me a bit especially in locks, as I'd be on my own on it. As a novice boater something that's rolling all over the place wouldn't be confidence inspiring.
The search continues for something more conventional.
