Dave,what starter knot do you use for the lashings?
I prefer to use double braid polyester line for the lashing turns. This will stretch about 3-5%. For the frapping turns I like to use spectra . It is very low stretch and very slippery. I also will spray the lashings and frappings with dish soap to make it all more slippery. This enables me make the lashings very tight indeed.
Perhaps there are more complex knots, but it's hard to beat 2 round turns and a half-hitch, Paul. Another is a buntline hitch, though it will take needle-nose pliers to get it undone once it has been tightened in use.
For our Tiki46 I've used the same method as with our previous Tiki30 in turning the rope around a lever . But if it was OK for the Tiki30, with the Tiki46 the efforts are greater and especially when sailing in bad weather with steep cross waves.
I change of method in using a rectangular piece of wood of about 60 x 30 x 900mm with a hole at 100mm from one end. I use a 10mm rope for the lashings and a 8 mm rope for the frapping turns. So after to have attach the frapping rope around the lashing turns, I proceed half turn by half turn : the rope is passed through the hole + 1 turn around the lever and the end of the lever is apply on the lashing rope just below the frapping turns.
Now I can get a very great tension easier because the lever can't twist and I can concentrate all my effort on the tension. It's more easy to explain with pictures :
Hi Bertrand, tks for your interesting comments on this issue. I see you are in canaries; your next plans are to sail towards SW, I suppose. Did you already decided whether more W than S or more S than W ;-)
Hi Luis. I think we'll stay until mid September around La Gomera which is for us the best place in Canaries to stay at anchor with the possibility to return in the very quiet and welcome harbour of Tazacorte (on La Palma) if necessary. After we want to visit a few islands of the Cap Verde archipelago before to cross toward the Martinique in November.
We appreciate very much this long stop here, we began to enjoy the sea people life and we try to learn to speak Spanish.
As Marie-Helene is not ready to sail threw south America channels we'll not heading to the Brazil (and one other obstacle : now the Brazil refuse to European boats to stay more than 3 months). Our plan now is to pass threw the Panama canal next February.
So in a few years when we'll sail back in Atlantic, perhaps by south America, I hope we'll can visit you.
