On the previous boat, Reeves, the area just behind the bow strake steel used to get trashed up. I see the same thing on a lot of boats. I had some thick butyl rubber tube fenders made, hung low festoon-style to heavy staples on the gunnel just behind the cratch. These were marvellously effective in cushioning, for instance, the impact of an unfortunate swing in a lock, or the evil gouging of a section of exposed steel siding. Brilliant.
Only a couple of times in 10 yrs, at e.g Hurlestone, did we need to lift a fender tube to pass. I always wondered why this wasn't much more common. Seems obvious that the space-maximising square design of almost all NBs is inherently flawed in the bow-to-main square hull join. Loads of scrapes, rusting etc.
That was over 10 yrs ago.
Imagine my shock to discover how much today it would cost to have another 3m of 80mm butyl tube made for the new boat!
After a lot of internet searching, I have found HGV lorry bumper D extrusion tube. It's heavy stuff, a lot stiffer than butyl, and possibly a bit fatter. But at £80 for two 3m lengths, must be worth a shot. Hang and used it this weekend and so far I am impressed.
I see some boats with long knotted bow festoons, but interested to know if anyone else has tried my idea. I should say, Knowing the forum, that I couldn't give a toss for the holy helmsmen who never make contact with the edge. It's a canal, not the med.
