Wooden widebeam boat on Regents Canal. Dangerous?

[Paddle]

To answer your question, it's mostly dangerous for your bank balance rather than dangerous per se.

 

This is also wooden, and another project but it does have an engine and would fit up more canals than the one you propose. Plus you wouldn't have to ship it by road. All round I'd go for this one rather than the one you propose. But I'd still want £100k+++ in reserve.  https://www.facebook.com/marketplace/item/523005505298984/?ref=feed_rhc
