Replacing wire halyards with line on Columbia 26 MKII

I'm thinking about changing both my main and jib halyard to line from the original wire/line mix. I'm thinking about replacing them with 5/16" line. Does anyone know if the sheaves at the mast head will take 5/16" line?

Thanks.

I am contemplating the same switch on my Catalina 22. In my case the sheaves need to be changed to accommodate 5/16" line.

Re: Replacing wire halyards with line on Columbia 26 MKII

you do not need to change sheaves out...unless you really want to

new line is quite a bit stronger and less stretchy for the same diamater, SOOOOOOOOO

if you want to save some $$ especially on smaller boats, switch out the wire rope halyards to a 1 size down all line halyard...

cheers

Re: Replacing wire halyards with line on Columbia 26 MKII

I am going to do the same on my Coronado 25 BUT I am going with 3/8 as its easier on the hands AND I have the lines ready to come back to the cockpit, cabin top winch and rope clutches. I do have to change the sheaves cause I don't want my lines ruined by the grooves, I am also going internal and coming out the bottom of the mast. The red line in the pics is a fake just to line things up.

Re: Replacing wire halyards with line on Columbia 26 MKII

I considered the same change, but then realized that when the sails are raised, the entire run under stress is all wire except for the final 18 inches at the mast cleat... and 18 inches of line, no matter how old, can't stretch nearly as much as a full-run of new all-rope halyards will. Yes, my lines are old and a bit dirty, but the wire portions are still fine and in the final analysis I could come up with better ways of spending boat money.

If you race, wire has less wind-resistance too.

I'm not trying to challenge your thinking... but just share a conclusion I reached from the same circumstances.

Re: Replacing wire halyards with line on Columbia 26 MKII

Use non-stretch modern polymer line such as 'dyneema', or 'am-steel' etc. Typical daron polyester is simply too 'stretchy' to be used for halyards, especially if you heavily load-up your halyards to affect good sail shape and to hold that shape during 'heavy' wind conditions to prevent the sail(s) from 'power-ups'.

The only problem in replacing with polymer is if your current wire-rope halyard has a 'ball' swaged to the wire and the 'ball' fits into into a special 'ball cleat' to hold the wire tension (instead of a horned cleat).

Re: Replacing wire halyards with line on Columbia 26 MKII

I despise wire running rigging. Unless your halyard is all wire, the sheaves are configured to handle both wire and line. Changing to all line the same size as your existing tails is a matter of joining the tail of the old to the head of the new and hauling them up & over. I've done it many times.

I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.

What are the minuses to wire running rigging? What do you gain by changing it out?

Re: Replacing wire halyards with line on Columbia 26 MKII

you dont gain anything...only reason to replace is if they are fraying.

if you do replace I would recomend going 1 size down...no need to go same size since line today is much stronger per same size

thats just me though

Re: Replacing wire halyards with line on Columbia 26 MKII

Just replaced the wire/line main halyard on my Cal 33 with all line. Went with New England VPC which is a "mid tech" line. The cover on the old halyard was in bad shape in several spots, so it was time. Never considered staying with wire/line.
