Harlequin has a Sleipner bow thruster and I find it essential when reversing into a mooring singlehanded in the med. You have no steering in reverse on the Nic38 and the slightest cross-wind can make things really interesting.
Had a problem with the bow thruster one season – it was the first thing on my list to get fixed the following winter 🙂

To be honest I don’t think adding a trailing earth wire into the sea will make any difference for a full or partial strike. The inductance of the wire will probably present a higher impedance path than simply blasting through 15mm of hull. However it will reduce charge buildup for near strikes and ionisation effects so it will be a good thing to help protect electronics and occupants of the boat.
You could add an external earth plate close to the base of the mast and joined by a 3 inch, bend free, copper strap with a suitable bonding kit to prevent corrosion and electrolytic effects. It would certainly reduce damage in a strike but I’m not sure it is worth the effort.
Lightening is funny stuff, the current risetime is in the order of 8 microseconds and it will flash across a gap rather than go around a bend in the wire. I used to analyse radio tower grounding systems and the computation outputs used to surprise me sometimes. If you are really paranoid keep a spare radio and gps in a sealed tin box, they will then survive the electrical storm for later use to report the lightening damage in your holed boat.
By the way there is a lot of crap sold to protect installations and buildings, don’t touch early streamer or radioactive ionisation products, they are a complete waste of money. Use a good old Franklin rod and copper strap to a good earth rod (on land). It is just as good as anything else and costs a fraction of the high tech alternatives.

Ps,
I do know what I am talking about on this topic. Trust me, I’m an engineer :pThanks for the warning. Harlequin is coming out this month for antifouling so it is a good time to check. I’ve no doubt mine are in the same condition.
Harlequin has a large stainless steel tank with two removable covers immediately in front of the fuel tank. Its easier to open one of these and point the hose there than mess around with the filler cap. Don’t know the capacity but it it at least 300l. Looks like the tank has been installed since the boat was built as the flooring doesn’t appear to have been removed to fit it.

I’ve the user manuals for just about all the non-C&N accessories on my Nic38 (Hornet 4 for example). Many of them date back to the original commissioning of the vessel. I’ve an 18 inch pile of assorted paperwork.
Let me know if you have something which needs a manual – I might have it on Harlequin of Kerrera. Its easy enough to photo or scan most documents.
