What a great response. My thanks to everyone.
They use Bamar system which is moderately priced
The Bamar System
looks very interesting. It has its own halyard which is brought back down to the drum and the tail becomes the reefing line. I haven’t found prices yet.
"M.T. Pockets, the Jag 25 I had, was fitted with a Plastimo 608. It seemed to work OK but I would have classed it as "roller furling" rather than "roller reefing", i.e. it was all or nothing as I was never happy with it when it was part deployed.
The owner who fitted the furler used his old hank on genoa which was not a great success. He had sliders fitted to replace the piston hanks to attach the luff to the aluminium bit.
Was your unhappiness caused by the mechanics of keeeping the sail partially deployed or with the set / shape of the sail when part furled?Solitude
, my Leisure 17 has a Plastimo 406 and the genoa and jib were both sails which had been modified by removing the hanks and sewing on plastic sliders to fit the foil. All done by a previous owner and worked reasonably well.
I have a Plastimo 608 … but you must remember to keep a little tension on the furling line the whole time or it can slip off the drum: you then need a trip to the front before you can take the sail in or out.
I learnt that lesson with the Leisure. The line would get caught around the plastic flap which presses the line onto the drum.
I’m not sure if an enclosed drum is better than an open one – at least with an open drum it is easier to see and fix a problem.
They also said that happily fit foam luff but they didn't think anywhere near as effective as theory would have it.
I find the padding keeps the sail nice & flat & will sometimes put a few turns in when I want to point a bit higher.
Interesting difference of opinion – I would hope to achieve the same result as Arghiro.
It is on a Sailspar continuous line reefing system
which I initially thought we would change, but once we got used to using it we have never looked back - it works really well. The huge advantage is that it is impossible to get a foul-up on the drum.
I like the idea of a continuous line system from an engineering point of view – a much better leverage ratio on the reefing line and also a more comfortable line to handle. Bit more involved to install with double guides and cleats but it should give the maximum length of foil of any above deck drum system.
FWIW, I fitted a Plastimo 608 on my Westerly 25............
When I bought my Pentland I did the same, this time with a 910.
How much better is the bigger unit? It seems to have different bearings and a bigger capacity drum.
Plastimo quote the 608 for the Vega. I haven't measured the forestay yet, but I would like to maximise the length of foil. I think that I might need to add a section of foil to the 608 or throw away a bit on the 910.
Is the bigger unit worth an extra 15% to 30% to do the same job?
Thanks for everyone’s help so far – keep it coming. I’ll continue investigating further. The usual boaty problem of spiralling expenditure applies – better to fit the stronger stem head fitting from VAGB whilst I’m at it, etc.
I don't think that the 130% genoa and the jib are worth spending much money on, but I would like to be able to use the 150% genoa. It will depend whether the luff will fit the foil - time to get my 30M tape out and do some measuring.
