The Hobie 17 has inboard bolts and outboard castings that fit inside the ends of the cross bars where the meet the hull (at the little hump). Those casting are likely loose. They have two small "fingers" pokeing into the glass structure of the "humps". This is the vertical shear strength of the connection. They are held against the humps by small screws and possibly by sikaflex or 5200.

Dis-assemble the boat and remove the hulls / crossbars. Reseat the castings onto the hulls. You may have to fill the small "finger" holes behind the castings with resin and chopped glass. Re seat the castings with epoxy or 5200 and screws.

Be aware... the position of the castings is critical for a tight boat / ability to re-assemble. Position the castings carefully. Pre-fit with crossbars and check proper positions.

Matt,
What is better epoxy or 5200. Do people put also something under the cross beam (between the hull and the beam)? :roll:

Epoxy or 5200

Epoxy is harder and possibly more permanant. 5200 is like really strong rubber. 5200 in the saddle (bedding) can certainly help tighten up the connection.

Matt,

Last year I went through the process of disassembling my 17. I removed the crossbeam castings (not difficult since they were very loose) and used West system to put them back in place.

:?: My question regards your caution about postioning the castings exactly. How do you know they are in the correct position?

There is one gap on one crossbeam - about 1/8". Some epoxy could be between the casting and the hull cut out.

Exact location of the casting?

When it holds the beam fully seated in the saddle. If you use a bedding material, this is not as critical. If the beam is to high though, the edge of the extrusion may be protruding above the end "hump".

Just completed this same repair. You can glass or expoxy in the fingered fitting. Matt point of concern has to do with alignment on all four corners so when you put the boat back together again everything fits properly and snuggly.

Sail fast, Tom G

Posting images on this forum requires that the image be on a web server somewhere. I have an image directory on one of our servers that I then link to in a post. If the image is up somewhere... Right click and get the properties which will include the correct URL. Use the image button "[img]"%20then%20the%20URL%20and%20close%20with%20the%20image%20button%20again%20"[/img]".

Matt, sorry but I do not have a webserver on this end. I could email my castings pics directly to you.

There are a bunch of image hosting services out there. For free, you get very limited space, but for a nominal fee, you can get lots more space.

If you've got a high-speed internet connection, your ISP probably gives you storage space as well. (I know Comcast and SBC do.)

I use ImageMagician.com.
