I've been considering installing mast steps since Lori isn't comfortable with going up the mast and she isn't big enough to get my fat butt up there. I'm thinking they are a must for cruising, but I hate the idea of putting a bunch of holes in my stick.

If you have them, what are the best to buy and what is the best method of isolating them from the aluminum to prevent corrosion? Are there any good alternatives besides having a crew with someone small that isn't afraid of heights? What about folding steps since I already have four of them at the base of the mast to help stow the main?

Hi there,

I remember putting the same question to myself a few years ago - and after looking at many ideas and designs of mast steps - found a Canadian design that had would fold away giving least wind resistance , also designed in such away to ensure that line, halyards would not snag in the step.

I also managed to find a goop that would prevent stainless machine screws from binding in the tapped screw holes - the screw would fix part of the step combination to the mast. The goop came from an outfit in Portland - Oregon.

Subsequently , this design really caught on - only one hickup was a small teflon machine screw, which was meant to prevent it rattling. This screw was redesigned.

Here a picture of the design - Mast_Steps.jpg

I am not sure that Lori will be happy with steps as an alternative to being hauled up on an halyard ? http://www.cruiserlog.com/forums/style_emo...lt/rolleyes.gif

Folding mast steps are definitely worth installing. Mine are rivetted to the mast with monel blind rivets. The steps are cast aluminium, but just to be on the safe side, I used barium paste as a barrier against galvanic corrosion.

When installing the steps, you should not space them too far apart. An extra three steps on a tall mast will make the climb to the top much easier and more important, will make the descent much safer in a seaway. It will also make the climb easier for a person with shorter legs. It is wise to place a step on either side of the mast at a distance from the cap that will make standing with locked knees easy, and still provide a good , reasonably high point to attach your safety harness.

I have placed a 'dob' of silicone on the hooked end of each step, to prevent the steps rattling when folded. Of course it goes without saying that it is still important to clip onto a halyard and have someone tail it through a winch as you make the climb.

It also goes without saying, that in the marina, like most other idiots, I have clambered to the mast top without anyone else's help. This is extremely stupid. Keep the disinfectant handy.

Cheers

David.

Spot On, David.

Just don't forget to close each step on the way back down... two trips up the mast in one day and a guy my age is feeling it in the legs for a week!

To Life!

Richard,

Do you have a link for the manufacturer or distributor of those steps? Also, what are they made from? The four steps that I installed are chrome plated bronze. The chrome is giving way and they are turning green. I certainly don't want to install a bunch of green steps on my mast.

Ken

I know SELDEN sells 'em - but you can probably obtain them for less money from Defender or West marine. I seem to recall that they came in two models depending on the radius of the mast section. Mine were made from cast aluminum and cost somewhere between $15 ~ $20 each.

One should never go aloft without a harness of some sort and somebody tending on deck. I personally believe that mast steps are to be used only as a way for the climber to assist the person on deck to haul your heavy butt up the mast. And a prudent sailor would always use an additional safety teather.

Getting cripled or killed by falling from the mast would definitely ruin even the best day of sailing.

To Life,

Kirk

Hi Ken,

Here are a few URLS :-

http://www.ab-industries.com/fabrication.htm

http://www.blanchardrigging.com/index.html

http://www.mastwalker.com/

A&B have the best price for the cast solid polished aluminium steps (a third of the UK price - for essentially the same article)

Note :- if the mast is Ali and the steps are also Ali, then the problem is either the S/S machine screw or the remains of the steel pin in the blind rivet - if monel is used , they are sometimes fitted with monel break off pins . In any event, as David suggests the step should be fitted/bedded using a compound which precludes corrosion

Galvanic corrosion occurs when stainless steel or bronze fittings—cleats, tangs, winches—are installed metal-to-metal on an aluminium mast.

Every few years, mast fittings should be rebedded with zinc chromate paste, polysulfide, teflon, nylon, or tufnol (plastic) to protect the mast from galvanic corrosion. Silicone does a good job of protecting the mast, but the fittings may be difficult to get off later.

If a mast is painted, look for bubbles near fittings, which indicate corrosion. On an unpainted mast, look for white powder and pockmarks around fittings. Some powder, which is oxidized aluminum, is normal on an aluminum mast and is usually not significant. But heavy concentrations of powder, bubbles and/or pockmarks, especially deep pockmarks, indicates a serious problem that threatens the integrity of the rig. Contact a rigger or surveyor if you suspect a problem.

Ken,

I have not seen the nylon/glass equivalent of the aluminium folding step = I understand they

are rated for 300lb , whilst the aluminium has a rating of at least 500lb - so I guess Lori will be happy.

Richard

Yeah, I'm 6'4" 245#...Lori is only 5'7" 110# and scared to death of heights and sharks of all things! Her worst fear would be to hang from the mast and see sharks ;-)

So, the steps are going to be a must have item before we depart.

Thanks for the links guys!

Richard,

I think you gave the wrong link for A-B fabrication. I called and they said they don't make them. Do you have another link?

The best price I've found so far is $25.00/ea. I probably need between 30 and 40...ouch!

====

Just found several types on E-bay check these 316 stainless steps for $18.00/ea

Does anyone have suggestion on spacing of the step?

Ken,

Here is another link to another A & B industries (this one I checked out - it found the correct one , sorry about that) :- http://www.sailboatstuff.com/dk_hardware.html#maststep

the price is 18.95 US - free shipping.

The "mast steps" in the EBay link are not mast steps (but if 316 S/S - good price) these are a step that are to be used on transoms for example. Occasionally will be fitted at the bottom

of the mast to enable dropping the main etc. , I have even seen them on the side of of a boat to assist boarding.

To get the correct spacing - first go back to David's recommendations - take those on board ;

then sit on a chair - with your foot on the floor, thigh at a Rt. angle to the floor - measure the distance from the floor to the underside of the thigh - that will give you the minimum distance between steps, then measure the distance from the floor to the top of your thigh - that will give you an indication of the maximum distance between steps.

The rigger will then mark off the placement of each step - taking care to ensure that space is left between steps and shrouds, spreader,tangs etc... You will 2 opposing steps at positions where work may be required eg. the top of the mast, radar etc.. At the same fix a pad eye at positions where you can "clip on" your safety harness while working.

Richard

I have had the mastwalker style folding mast steps on my catamaran for the past twelve years. They have been trouble free, and have made working on my rigging and masthead safer and easier.

Rigging inspection is mandatory before sailing offshore. Using my mast steps, I make the trip up the mast before every offshore passage - no excuses accepted. Because of these inspections, I have discovered broken rigging strands in Bora Bora, Fiji, New Zealand, Australia, Turkey, and Gibraltar. My mast steps made it easy to discover those broken wire strands before they caused a problem.

Long live folding mast steps.

Cheers,

Thanks Maxingout, your advice on rigging inspection topsides very useful and it complements the topic perfectly.

By the way, I had great fun teasing a Non-Sailor friend of mine - when showing a photo of cat

"Exit" explaining that this boat was driven by 2 small wind props electrically driven from batteries charged by these same 2 generators :-
