After trying many different mainsheet systems I have changed my 1 metre wide Amiot traveler for a 1.8 metre wide Harken big boat CB traveler with a massive dual high load car. Because the high load car is very wide the 1.8 metre track is not excessive. To fix the ends to the deck I fabricated some solid fibreglass spacers with the bold holes cast in. They provide a professional finish to the installation and the sloping outer ends are designed to reduce the chance of the mainsheet catching on the traveler end.  |

Looks like a great job. Some day I will try the same. Joe

I'm getting a 2m traveller mounted on my SO40. I was planning to get a stainless mount made, but after seeing this I have asked the people who are mounting it to give me a price for doing it this way. I like the way that it looks "standard".  |

You have a traveler on the top of a cabin?!?!! what good does it do to be there?!?!?!?
Says the person that has only sailed on ONE boat with a cabin top traveler......it was not fun, hard to adjust things.......
Looks better than stock!
marty
oh yes, had to have a bit o phun on april fools day.......i have about 3 hrs left!lololool

Marty,
Now that it is way past 1st April is it safe to post again??
Our mainsail is about the same size as a SO40 so I went for the heavy duty double cars and while I am happy with the result I was somewhat surprised how much load is on the 4:1 traveler adjustment. We do have two winches either side of the coachroof so for racing we will run the traveler tails to the winches.
I am very pleased with my fibreglass spacers. I made a plug from foam which is easily cut with a sharp knife and then shaped with a wood rasp. Once the basic shape with all the taper needed for mould was finalised the foam was covered with a layer of glass and then flow coat to finish the plug. Much sanding and polishing later it became the plug for the mould. The mould was made with four layers of chopped strand mat with tooling resin. Once the plug was out of the mould I polished that with release wax and made up the shells of the spacers with again four layers of chopped strand mat and tooling resin. When these were out of the mould I purchased some plastic pipe to form the bolt holes and poured in a mixture of tooling resin, filler and chopped strands which makes a super strong spacer. Once cured the plastic pipe was removed but it could have been left in place. The precast bolt holes gave a little room for adjusting the spacer position and saved having to drill through 120 mm of solid fibreglass.
Just in relation to the traveler being on the coachroof rather than in the cockpit, all the crew are very pleased and we have no more near misses. The other advantage is that when cruising we can put in the infill panel between the spray dodger and bimini and have a large area sheltered from sun or rain. The downside is that we have a heavier boom than an end sheeted one.
Regards
David

Nice job looks great.
I did similar on a 33i with big boat track and even then I found we needed 6:1 on the traveller. I mounted extra 57mm carbo blocks to the mainsheet toggle and the up risers to achieve it. I used 6mm rope as that seemed to lower the friction but the crew hate it from a handling point of view.
It would seem harkens estimate of 0.2 of mainsheet loads for the load on the traveller is a little off. Either that or the block friction is high.

David,
That design looks a LOT better than some I have seen. One Catalina 34 on my dock, the halyards come from the mast via deck organizers, attempt to go thru the fiberglass blocks to the clutch behind the risers! So the halyards etc ALL rub going around the riser blocks, causing major amounts of drag......This is just one of the cabin top setups that makes me wonder why Travelers on the cabin top exist.
The boat I raced on, granted a Hunter 53 or 54'?!?!? anyway, they had a full dodger, bimini, the dodger was designed in such a way, you could not use a full turn of the cabin top winches, along with some drag around the risers also for some lines.
The riggin designs seemed like an after thought to the interior, or the as some say "I'm a cruiser, i do not need a high tech well designed rig setup"......I think EVERYONE wants a boat that sails well, can have things adjusted easy. You're design looks pretty good at the surface any how vs stock, and jeanneau's are pretty decent stock.
