    Posted: 24 October 2018 at 08:39
Hi Guys,
Looking into getting a code zero for cruising and offshore for my 415. I had the local sail maker tell me that because the boat and spreaders are so wide, I wont achieve the upwind angles I would like (due to the sheeting angle etc. of the code zero). Does anyone have experience here with what angels they can achieve with theirs? 
Im looking a fractional code zero as im not too keen on adding another box and halyard up top. I know that this may sacrifice a couple of meters of sail area.
Thanks a lot! Jeremy

Hi we have a code 0 using the spinnaker halyard, I.e not the top of the mast but about 30cm above the forestry the closest angle is 50 degrees before it stops being of any use and starts to pull the boat sideways. But it really depends on halyard tension which can be quite high so I would definitely use a bob stay

Thanks Paul,
Any idea what sqm your one is and what length the foot would be?

Hi, I have looked for the original invoice / details but canít find. I know that it is 100 sq m and from comparing it to our gennaker I would say the foot is about 9.5 m. Next time we unfurl it I will measure it

HI Paul,
Thanks for that. That does seem very big. My Gennaker is 100sqm. 
Were buying one for cruising. Would you recommend one of these before the 105% Genoa? Presently we just have the self tacker. Thanks again.

Hi we havenít got a 105% jib, I couldnít really see the point for an additional few square metres. At the end of the day if the wind is 5kn or less a 415 will never be a fast boat! We use the code 0 and a furlstrom gennaker without any issues. For racing we have a carbon self tracker which we find makes an appreciable difference

I thought a code zero was basically a Gennaker. What is the difference?

Hi, a gennaker is cut fuller and generally uses lighter cloth so is best suited for downwind sailing, code 0 is flatter and can be sheeted tighter so can be used closer to the wind

Hi Paul
Im getting quotes and designs for a code 0. Fractional. They are all ranging in size from 67sqm to 87sqm and I remember you said yours was 100sqm which seems really big.
Im worried that if I go that big the boat will be overpowered upwind too easily. But I dont want to under do it either. What do you think? I was wondering if you have a copy of your dimensions available.
Also, what angle upwind are you able to achieve (apparent) with yours?
Im making this for 2 handed cruising, not so much racing like you, keeping that in mind.
Thanks, Jeremy.

Hi Jeremy, i now have my new code 0 in my possession and awaiting delivery of my selden cx25 fuller next week.

My sail is 90.5m2 17.3m luff, my spinnaker halyard exits the mast just above my forestay so not enough clearance for top swivel, i am adding additional exit box at top of the mast and will install 2:1 dyneema halyard. Code 0 have much higher loads than gennakers particularly on the wind.

Haven't yet decided if i will attach the bottom fuller to existing bow padeye just forward of the forestay or if i will add a prod/bow sprit of some sort, will be a bit of trial and error, i don't want to compromise anchoring so want the ability to hoist code 0 and leave it up and furled and anchor if need be. Many prod solutions limit this as they sit across the anchor locker lid.

Your welcome to have a look.

Stephen
