I am planning to add a spinnaker to my 16. I found a spinnaker sail that came from a 24ft Seafarer; Does anyone know what the sail dimensions are for a spinnaker on a H16?

This one's probably over sized but I'm not sure where to start. Any input on size ranges would be very helpful.

Thanks in advance!

A spinnaker for a monohull is entirely the wrong shape for a catamaran.

Most monohull spinnakers are symmetrical and full and meant for sailing dead downwind. Catamaran spinnakers are assymetrical and flat and meant for VMG reaching at ~45 degrees apparent wind. They're more like a large jib sail than a conventional spinnaker.

What you have is completely useless on a Hobie 16.

The Hobie 16 spinnaker is quite small.

My buddy just put a spinnaker on his boat. I think he said it was 12 or 13 meters square. We're having a blast! He is already talking about a larger one now.

This should get you started in the right direction.

THANKS to all!

I think the H16 spins are typically smaller for a reason. The mast tang is just pop riveted into plastic with the comp tip. If you have an older all alum mast you're golden.

I do actually, I have the one piece extrusion. WooHoo.

Have you (or anybody) seen or heard of The Hooter: http://www.catsailor.com/bestof_articles/Hooter.html

Thoughts? Opinions? Concerns?

Saw one on a H14 a couple years ago. Don't remember much detail though.

I double checked the spinnaker size. It's 128 square feet. Everything is totally home grown. He made it with an industrial sewing machine and a $300 sail kit. The rest was modeled from the cat sailor link above, the Hobie Europe instructions and a lot of scientific guesswork (trial and error). Boom from a sawed off wind surfer mast. Piece parts (spin lock cleats, ratchet blocks, sheet rope etc) all begged, borrowed and purchased. We had a Hobie Tiger and a Nacra F18 to look at so we weren't flying totally blind.

Thanks Sunvista! Sound's exactly like the process I am engaging! One bummer is that a couple of years ago I "freecycled" a windsurfer that I had received via freecycle myself. Would've, could've, should've.....

Jman6631 did you put together a DIY Spinnaker setup for your Hobie 16? I would like to try and do the same thing. If so, please tell us how? Exact sail size too.

Did you go with a windsurfer mast for the pole?

I'm eager to add on to my Hobie 16

Thanks,
Mike

Thanks David,
I found the Hobie 16 Spinnaker on catsailor at the following sizes:
Luff = 21.5'
Foot = 9'
Leech = 18.7'

2' longer luff? I wonder why the difference. :?:

Mike

MG dimension is critical.

Do You have a MG Dimension? What is a MG Dimension? :oops:

Also, any one now what size and length the lines are for a midpole snuffer system?

Halyard/dousing line (loop)?
Tack Line?
Spinnaker Sheet (Loop)?

Would 40mm carbo and auto ratcheting blocks be suitable for the sheets?
What size blocks for the halyard & tack lines?

I'm gathering all my blocks now. I just purchased the aluminum pipe that will be my pole.

Thanks,
