Humber Destroyer Winter Refurb

Hi all,

I have been a regular reader to all the great advice on this forum for a while and have gained a lot of knowledge (plus a few laughs, especially a certain "ski boat operator" down our way in South Wales!). After taking useful points from lots of other builds and fixes I thought it was time to give something back and hopefully someone else will be inspired or find something useful.

Our club dive RIB was looking extremely tired and things kept failing and requiring constant maintenance (mostly electrics). A few bodge jobs had been done in the past making diagnosing faults tricky. Add to this some shocking build quality from Humber out of the factory and after 13 years of use it was decided it was time for considerable improvements. In the past 2 months the following has been done:

- Steering helm unit replaced (old one jammed at high speeds!). The steering boss was seized on the shaft so had to be cut through. As you can see from the pictures the inside of the console was nasty and hadn't been sealed properly.
- Engine lock cut off - old one was seized and engine had been set up far too low by Humber. The lock did a superb job as it was a bugger to remove but the handling and speed improvements were drastic when the engine was moved up a hole.
- With 8 divers on boat the cut out in the transom meant it regularly flooded so I made up a piece of acrylic to partially cover the gap and give 3 inches of extra height. The difference is instantly noticeable - a dry boat!


More pictures and the more interesting stuff (incl LED trailer lights) to come shortly.

As you can probably see from the state of the wiring in the pictures it was an absolute mess. Every single piece of wire except the engine loom came out and was replaced. A while back the previous caretakers of the boat had used poor quality, non waterproof connectors and in one case had just shoved the important electronics ground wires onto the tacho post with no connector!

The battery was corroded (and undersized) so got the chop for a new Numax marine unit. However the engine was still sluggish to start. I later found out that Humber had fitted 16mm^2 cables for a 4m run when the manual says at least double that! New bigger cables fitted and all was well.

New LED nav lights and flood lights were fitted to the A frame and wired up to a custom made laser cut switch panel with a variety of carling switches. A Blue sea systems mini isolator switch was put in to replace the basic plastic key type originally installed.

End result could have been neater but a hell of a lot better than before. Proper heatshrink connectors and new cables run right from console to A frame (including many frustrating attempts to feed cable through conduit and a frame!).

So now onto the trailer.

The boat was previously strapped to trailer with a ratchet strap over the tubes. It really annoyed me as it deformed the tubes, tension changed depending on temperature and allowed the boat to bounce. So on taking over looking after the boat I wanted to get rid of it. It could have been solved using a couple of basic straps but we decided the investment of a couple of boatbuckles would be worth it for the ease of use. A couple of holes in the trailer later and everything is much quicker and more secure.

Another pet hate was putting lightboards on and off all the time plus their inevitable failure at the worst moment. I therefore decided to make up two submersible LED units (thanks go to Nasher for the inspiration on this one). The parts were from LED autolamps but with an additional fog lamp added to the G2 system as its not there as standard. Load resistors were added to the junction box on the winch post. The lights were mounted on a laser cut backing and secured to the light arms with a welded bracket. This allows them to be extended for towing and retracted for launch and recovery. The time saved really adds up especially on a day trip.

The final job was to do a proper wiring diagram to make any fault finding simple in the future.

Only remaining problem is the trim sender. The bolt has sheared on the old one and despite many different attempts to remove it I have had no luck. May have to resort to having a short piece of threaded rod welded on and using a nut to secure. Anyone got any good other ideas?

Good job
Sometimes it's best to rip it all out and start from scratch. There are probably thousands of boats out there that have been chopped and changed lots of times over the years and could do with the same treatment. Is mine one? Not quite but not far off!

I have personal experience and heard more than a few similar stories of dive club owned boats. Often the 'caretaker' changes regularly, if not annually, meaning that a constant maintenance regime is difficult to maintain.
Good work but be careful you do not become a dedicated boat maintainer to the detriment of your diving
