Genoa Reefing Marks?

Can anyone give me the measurements from the tack to the reefing marks on an original Belize genoa?

(The PO replaced the genoa and there are no reefing marks)

TIA.

Better to talk to your sailmaker

Re: Genoa Reefing Marks?

Unless he has worked on a Belize genoa and recorded where the marks are, he won't know any more than me.

I have worked out that the genoa is 130% based on measurements and calculated where the marks need to be for a smaller percentage sail. ( 115%, 110%, 100% 85% etc). The problem is that the Belize manual sail plan gives reefing instructions for the genoa by referring to "the first reef mark", "the second reef mark" for various wind speeds. Nowhere does it say whether the "second mark" is 100%, 90%, 85% or what!

If someone can tell me where those marks are, I will know the FP recommended sail plan (and can work out what percentage of sail that represents.)

(I'm guessing that they will likely be 110% and 85% based on the full 130% but would like confirmation)

Looks like no one knows (or cares )
I'm currently in PNG and the boat is still in Aus and I haven't taken actual measurements, but working of a drawing, the standard genoa calculates at 133% (could be 130-135%?) with a foot of 6.5m.

So a reef mark at 50cm from the tack would be around 110% and one at 125cm from the tack would be around 85%.

Those proportions sound logical to me as reef positions.

Any suggestions/comments/criticisms of my figures?

HI Stu,


I am just not sure why you should care what FP think (and I say this as one who has owned two FPs including our current Orana).


I think you should talk to a sailmaker and a rigger and get their input and then apply your experience to give you marks that suit YOU and the way you want to sail ( and reef).


Just my thoughts.


On the Orana we reef (furl) the headsail to the point we think is correct for the conditions.


Use the marks as a guide. So I agree with what you are now proposing.

Re: Genoa Reefing Marks?

I am in a similar situation in that my new Genoa came from the sailmaker without the reef indicators. The sail plan (Plan de Voilure) in y owner's manual has two tables in the upper left corner under the title "TABLES DE REDUCTION DE VOILURE". The one for the "GENOIS" lists 90, 75, 60, and 45 for % reductions. Hope this helps.
