Wave Jib spreader bar dimensions

I have been trying to purchase a aluminum spreader bar (Hobie Wave Bow Spreader - 38999021). I have searched many sites, but cannot seem to find any in stock. I want to put a jib on my Wave.

Would anyone be able to provide the dimensions so I can build one?

Tube outer diameter
Tube inner diameter
Tube length


Thanks!

I was able to solve the issue of not being able to purchase a wave spreader bar. I was able to make one.

I purchased two spreader bar end pieces from West Coast sailing. These fit perfectly in to an old H16 rudder cross bar I have. I just needed to cut the bar to 65 inches to fit my Wave.

I also need a Wave spreader bar, but I don't have an old H16 rudder crossbar lying around. Were you able to figure out the dimensions, besides the length? I am planning on buying some aluminum pipe and making my own, but trying to figure out the inside diameter feels important to me.

I also need a Wave jib spreader bar. Did you ever figure out the dimensions? I plan to make one out of a piece of aluminum tubing. I think that it needs to be 65 1/4" long, with an interior diameter of 1/2". I don't know what the outside diameter of the tubing should be or the thickness of the tubing walls. Any thoughts on that?

I just ordered this, its over kill...

1" OD x 0.25" Wall x 0.5" ID Aluminum Round Tube 6061-T6-Extruded from on line metals .com. The OD for the plastic bushing is a weird size, I'm going to omit it and mount the tubing right on the bow tangs. Probably use some silicone to prevent corrosion from dis-similar metals. I could drill out the ends to use the plastic spacers worst case, no idea how to add a picture

Hi !
Reading this reminds me of the challenges that come with maintaining and upgrading older boats. Some parts disappear from the usual suppliers, and it takes creativity to keep everything working. It’s encouraging to see sailors putting effort into documenting and sharing their progress so others can benefit down the road.

I use a 304 SS tube. It's not 316 so it will rust a bit but never enough to compromise structural integrity. You could probably go with a smaller diameter but I wanted something VERY beefy so that it can be used to hoist onto my tall trailer and strap it down to my trailer tongue. It's so strong that I can stand on it. I weight 175lbs. I got it from Metals Depot for $100 after tax and shipping.

1-1/2" OD X .065" wall X 1.370" ID 304 Stainless Round Tube - POLISHED 180 Grit

I bought the Hobie spreader bar tangs -- they are beefy as well. I use female PVC end caps with a hole drilled in it to accommodate the tang. Lastly, I have some SS fender washers to take up all the slack, as I wanted a tight fit. I probably didn't need the fender washers if I hadn't cut the tube a smidge too short.

Works great. It's so strong that I might attach the jib halyard directly to the tubing instead of using a bridle.
