How to crimp!..


CrimpingI had an email from a reader asking me about one of the links over here on the right hand sidebar under “Useful Info” – and it reminded me to look at some of my links again!…

One of the links that I just loved is from an author who goes by the handle “mainecrusing”. He has numerous “HowTo” pages here. There are lots of photos for each job and I have certainly found them very helpful – check out the one on crimping tools for example.

…”In this photo I have lined up some of my wire crimper’s. The one on the far left IS NOT A CRIMPER! I only say this because I have witnessed people putting together marine terminations with a pair of PLIERS!!

The next crimper, the one with the yellow handles, is a cheap hardware store quality crimper and should only ever be used in an absolute emergency.

The middle crimper is a decent quality Klein crimper though it’s not really well suited for much other than crimping non-insulated terminals. The fourth crimper is a good quality crimper, made by Ancor Products, and designed specifically for crimping marine or aviation grade heat shrink terminations. The jaws of this crimper are precision machined, and wide enough in cross section, to produce an excellent crimp. This crimper is also of the ratcheting type and will not release until a proper crimp has been made. The final crimper shown is another ratcheting type crimper but this one, set up with the jaws shown, is designed for insulated terminals. ….”

Mainecrusing also has a YouTube video channel although that appears to be of less help since he seems averse to actually speaking. He is obviously quite a guy – this link shows him replacing a diesel engine on his yacht – single handed!

On a related note to the “howto” of crimping is the issue of keeping joints clean and free of corrosion – perhaps one of the hundreds of connections that you didn’t do or that some “professional” did when the installed your chart plotter or radar …grrrr!

This is a list of techniques and products that you might consider:

  • Tin the wire – if you can access it and have enough spare wire to play with
  • Coat the joint with Vaseline or petroleum jelly – after cleaning the corrosion off with emery paper
  • Spray the joint with Conformal Coating – again, after cleaning if possible

Or use one of the combination grease + conductive materials type pastes :-


Wiring supplierFinally there are many obvious places to go to get electrical supplies – and many of us – me included have bought stuff in car accessory shops to save money. This eBay supplier – Genuinedealz – seems to have a lot of good feedback from people- they ship free in the USA and UPS to the UK.

Genuinedealz actually stock real marine grade parts, tinned wire, lugs, tools and is also a great place to compare the electrical properties of wire and accessories before you jump in and buy something.

Happy Crimping !

Active Captain Bargain for Cyber Monday 2010….

MaxSea Ad

Not to be outdone by the many online deals going on today, MaxSea and Furuno have teamed up with a great deal of their own, a rebate on purchases of MaxSea Time Zero Navigator software.

If you purchase MaxSea Time Zero Navigator between October 27, 2010 and March 15, 2011, they will provide a $100 rebate. You must fill out and return the rebate form. The rebate form can be downloaded here.

With this rebate, the effective price of getting the full software with all US NOAA charts (vector and raster, 3D data, satellite imagery) and ActiveCaptain offline overlay support is only $239.

There is no one who offers a lower price for this product and it’s now $100 less.

Order it at Active Captain


But – be careful – The MaxSea TZ Navigator (about $350) is not the same as MaxSea TZ Explorer (about $1,000)….and neither are the same as MazSea Navigator 12.6 !! ($400)

For non TimeZero software see this comparison chart – and for TimeZero software see here.

I have been using MazSea TZ Navigator with the routing and weather options all last season  and I planned on writing up my findings – but – well time has eluded me….er, having too much fun!



Tracking GPS for £149 and 3G bundled in …

WPT250 facing left

We’ve all had those niggling worries about tying up our boat whilst we head ashore for a bite to eat and the thoughts of it not being there when we get back!

Tetra Boats are launching a new product called TenderTrack at the 2011 London Boat Show. TenderTrack is about the size of a box of matches and incorporates a highly sensitive 50 channel GPS and GSM data modem to allow the location of your tender to be constantly monitored on your smart phone. It’s waterproof and has an internal rechargeable battery that can offer up to 72 hours of operation.

Simply mount the unit on the tender or outboard (it can take temperatures of up to 70C, so can even sit inside an outboard cowling) and access its functionality through either sending SMS commands to the unit or through a simple web interface.

I don’t see why you couldn’t use this on your car or motor bike or even on your prize pot plant in your front garden – what a great gadget!

EV Supercar is here – EV Super yachts are coming…

SRZeroIn my previous posts about hybrid technology I speculated about the cross over effect of the car industry’s recent experiments and the possible impact on yacht propulsion.

In a week where Toyota announced that it is planning to release 11 new hybrid vehicles and a rechargeable Prius model as part of its efforts to stay at the forefront of low carbon vehicle technology – we have the fantastic achievement of our very own Imperial College team who drove a modified electric sport scar (donated by Radical Sport scars based in Peterborough, UK) from Alaska, down the Pan-American Highway, finishing at Ushuaia in Argentina, a journey of 26,000km – crossing 14 countries in 140 days.

This all-electric SRZero supercar is powered by the latest in lithium iron phosphate battery technology, linked to a state of the art battery management and systems control unit. Making a total of 400 HP from its twin motors, the lightweight BEV sports car can sprint from 0 to 60 MPH in just 3.5 seconds and reach a top speed of 120 MPH. Thanks to regenerative braking units built into the zero emissions race car, the SRZero has an extended range of over 300 miles and can be recharged by an ordinary household electric outlets.

Well that didn’t take long! – following my last post on systems for handling code-zero sails – especially while shorthanded, a number of readers sent me some interesting video clips from YouTube that I though I would share with you here…have a look – some are quite entertaining…
