Hull alignment and crossbeam position
12 Replies

I had to dismantle my Tiki 46 and lift the crossbeams in order to change the pinholes on the crossbeams according to the design. Those crossbeams had pintight holes before, and in addition where…Continue

"Hi Shelmy, its great to hear from you. I had mobile homes myself, since back in the 80ies, and travelled a lot in Europe.  I loved it, and would like to do more, but it does not go together with sailing.  I will soon start to post…"

"Hi, does anyone know what happened to the PCA website? I cannot open it, it looks like it had been deactivated. Is there any other access to this wonderful collection of the old Sea People magazines? Thanks for any help Helles"

"Excuse me before I began  building a James Wharram  catamaran I did not know a millimeter from a centimeter and I still don't very well, I was thinking  12 mm alignment rather than centimeters. Certainly as a builder this is…"

boatsmith replied to Cute Helles's discussion Hull alignment and crossbeam position
"It might be that the hulls were planked up with a twist in 1 or both hulls. This might make it impossible for everything to line up.  If you can't plumb up the stems and stern posts at the same time this would indicate twist in the…"

"i would change it. you are since a few years now on this boatyard. this little more work will not change a lot but i belive that the boat will be better .... just do it... and don't worry after it anymore.. hans"

Rob and Beth Boase replied to Cute Helles's discussion Hull alignment and crossbeam position
"The 12cm off parallel over 46ft is 12cm too much in my view. That amount of toe in or toe out must affect performance and if nothing else would create some interesting whirlpools behind the boat at speed!  To set our Tiki 30 hulls square…"

Bertrand FERCOT replied to Cute Helles's discussion Hull alignment and crossbeam position
"Hello cute Sorry but I can't understand exactely the modifications of the builder. Can you post a few pictures? For me 12cm is too much but to reduce it you have to modify all the beam holes! As I explained in my Tiki46 building blog, I think…"

boatsmith replied to Cute Helles's discussion Hull alignment and crossbeam position
"Lining up the hulls parallely, plumbly, and square  is a bit of work. It is certainly possible that someone stopped at fugingudnuf. 120 mm is 4+ inches  is way more than I would allow. We plumb up the sternposts and stems. We measure…"

Brad replied to Cute Helles's discussion Hull alignment and crossbeam position
"One cannot build a boat perfectly. Errors in measurement will be made but most will cancel each out in the long run. That does not mean we should be sloppy in boat building. If the two hulls are aligned the boat slips through the water with the…"

Robert replied to Cute Helles's discussion Hull alignment and crossbeam position
"Hi Cute, you have about 0.5 degrees of toe out, which is regarded as acceptable toe out for many cars, so I would not worry about that if it is going to be a lot of work to change.  As far as I can tell there is no list of acceptable…"

George Ray replied to Cute Helles's discussion Hull alignment and crossbeam position

Brad replied to Cute Helles's discussion Hull alignment and crossbeam position
"I've built another design catamaran, so I can only comment on the keel alignment on that build. But 12cm of difference from the front keel centerline to the rear keel centerline is WAY too much. You are pushing a wedge of water sideways in…"

john james replied to Cute Helles's discussion Hull alignment and crossbeam position
"CuteHelles-don't worry be happy-I should think the 12 cm over 46 foot boat length is not so bad. I would endeavor to bring the hardwood pads all into play .I mean the crossbeam should be resting on all eight of them as much as your patience…"

We have an asymetrical light air sail on Peace IV which we bought from Jeckyls in Britain.  It works fine but I cannot say what the dinensions are because we have never measured it and I doubt that it is anywhere near as big as Chris J says it is.  We have a snuffer sock that also works well.  We attach the tack of the sail to a shackle that joins a pair of lines that we can adjust to move the tack from the port side of the bow to the starboard side.  These lines run through blocks we have tied to the bows and from there to the aft end of the forward mast case where we have some jam cleats.  The sheets for the sail run outside everything to blocks well aft and from there to the usual jib sheet winches.  It is a fun sail in very light airs but I must be reminded to take it down as winds strengthen!
