Brisso57 Posted October 21, 2013 Report Share Posted October 21, 2013 Hi AllI have a copy of a 7 page tuning guide, and I'm assuming copies were handed out by Calypso Sailcraft some years ago (as it has a CS stamp on the first page).Barry, on the off-chance you may read this, do you have any objection to me uploading the document to this forum?Doug Link to comment Share on other sites More sharing options...
Brisso57 Posted October 22, 2013 Author Report Share Posted October 22, 2013 OK. I've considered the matter and I've decided that the document is in the public domain, so I'll upload it as a pdf file, in 3 parts (because of the upload size restriction) * If you do print this document, or pass it on, please ensure the author (Barry Allen) is correctly credited. * The document may not be used in a commercial manner without first obtaining permission from the author.

Shane Posted October 23, 2013 Report Share Posted October 23, 2013 hmmz - is a bit strange that taking the shine off rudders / hulls would reduce water resistanceThat was bit about the jib and furler was interesting Link to comment Share on other sites More sharing options...

madboutcats Posted October 24, 2013 Report Share Posted October 24, 2013 When I had a blast with Robbie on his Calypso 16 on the weekend I noticed that his mainsheet to boom attachment point was a fair way behind the traveller (didn't measure but looked a good 6 inches) when the boom is centred, is that normal for Calypso 16 booms? I felt I couldn't centre the boom to point upwind without unduly compressing the boom and putting a bend in it. If it was mine I would put a new attachment point to the boom just behind the traveller but I wonder it the sails and rig were designed not to centre the boom Link to comment Share on other sites More sharing options...

So you think just behind the traveler is a better? Check out this hand out from calypso, it's hard to see but it looks like their booms are bending a fair bit too when it's sheeted in... Hard to know if that's a design fault or like that for a purpose. http://www.johncrawfordmarine.com.au/trailer-sailer/library/cat_view/27-trailer-sailer-library/100-calypso-cats Link to comment Share on other sites More sharing options...
madboutcats Posted October 28, 2013 Report Share Posted October 28, 2013 Yep that's the same bend, I think you are putting undue stress on your boom and boom gooseneck and I feel you can't centre the main sail even when bending the boom as your attachment is a fair way aft and therefore the sheet is still long enough to pull to leeward, therefore you can't point as well. If it was mine I would move the attachment point to just behind the traveller when centred.I see that Chris has found another Calypso 16 for sale in the Garden Cats thread you should get one of your mates to snaffle it.

Robbieandrew Posted October 28, 2013 Report Share Posted October 28, 2013 Sounds like good logic to me, I'll move it forward this weekend, I never pass up an opportunity to play with my rivet gun! Link to comment Share on other sites More sharing options...

madboutcats Posted October 28, 2013 Report Share Posted October 28, 2013 If you make the change Robbie remember your mast and gooseneck rotate, so as a rough guide you need to rotate the mast with gooseneck at 90 degrees then allow the attachment point to be slightly behind the traveller when the boom is out about a foot from centre as that is about your reach position and you don't want the boom to be pulling away from the mast Link to comment Share on other sites More sharing options...
madboutcats Posted October 30, 2013 Report Share Posted October 30, 2013 Have a look at how many attachment points this one has on the boom in picture 2, it looks like it must double as a clothes hanger http://www.gumtree.com.au/s-ad/jimboomba/sail-boats/calypso-catamaran-not-hobie/1030451071 Link to comment Share on other sites More sharing options...
Robbieandrew Posted October 31, 2013 Report Share Posted October 31, 2013 Haha probably. That's not an original calypso boom though. I think I'll rig it once more as is to best figure out where to re attach the hanger, then I can mark while it's all rigged and make sure I get it right!

Brisso57 Posted March 10, 2014 Author Report Share Posted March 10, 2014 Have a look at how many attachment points this one has on the boom in picture 2, it looks like it must double as a clothes hanger http://www.gumtree.com.au/s-ad/jimboomba/sail-boats/calypso-catamaran-not-hobie/1030451071 I can answer this one. Norman Jones told me last weekend that early Calypso 16's had 2 attachment points for the mainsheet for the simple reason that double blocks were far cheaper than triples, so two blocks were fitted to the boom (3 blocks in total for the mainsheet) to keep the sticker price down! In Norman's opinion, simply using the rear of the two points is quite safe if you wish to use the later set-up of 2 blocks. ... & so that's what I'm going to do.
