Posts: 105 Bloomington, IN | The trailer for my used Tiger came with hull cradles that look like the ones listed as "INTER CRADLES FOR CAT TRAX" in the Catamaran Sailor online store. They are basically U-shaped and don't fit the front of the boat very well. While no damage has resulted (yet), I wonder if there isn't a better choice. Recommendations?

Posts: 105 Bloomington, IN | I suspect if the hulls haven't dented yet, the ones I have are okay. I'm interested in these cradles: http://www.onlinemarinestore.com/tek9.asp?pg=products&specific=jmoscqmqh4(made for H-20 bow N 5.7 stern) since they mount direct to the 2x2 frame tube, and I would like to lower the bows some while on the trailer as they ride pretty high now. I can't imagine why they wouldn't work as well as the current cradles. Dan - are those the H-20 cradles you are using, or are you using the Hobie H-20 cradles? (the Hobie cradles have a flat 3" x 6" bottom for mounting rather than a cutout that goes around the trailer frame).

Posts: 851 US Western Continental Shelf | Jeff, I was able to lower my front cradles by about four inches simply by moving my trailer's support bar from atop the frame to beneath the frame.
Note that this may cause problems with both storage box mounting and with 'box to dolphin striker' clearance.

Perhaps you can use wax paper around the hulls and make a form out of the stuff. Who knows, it may work. Rick I've tried to use that stuff for molds before - it really doesn't have much structure too it and I crushed it with some really light vacuum bagging. It might suffice for some light duty padding for something - but it would flatten pretty quickly with boat weight.

Perhaps you can use wax paper around the hulls and make a form out of the stuff. Who knows, it may work. Rick I used that type of foam in 5 ltr rectangular plastic water containers about 7 years ago. It made them very solid. I ran a loop of shockcord through a hole in the end, with a stopper knot inside the container (before I squirted in the foam). The shockcord went round the hull and was held around the neck of the container. The guy who bough my Hawk is still using them.

Posts: 105 Bloomington, IN | Gary, my front crossbars are welded to the frame and also have a small diagional bracing piece welded in, so they would be a bit of trouble to move. Good idea for bolted together trailers though. I went ahead and order these: http://www.onlinemarinestore.com/tek9.asp?pg=products&specific=jmoscqmqh4They just arrived and I held one up against the hull. Just forward of the current cradles there is a little extra room on the sides, just aft of the current cradles they are a bit tight on the sides, so I expect a darn near perfect fit when I get them mounted. The current cradles are roughly 18" forward of the front beam when the boat is in its proper position on the trailer. Another problem with the current cradles is that they are built with "pockets" in the center. Although they were supposedly sealed when made, they now leak and collect water. Not good in a climate with freezing temps. Also, the carpet sags over the pocket so you end up with a little support strip just foward and aft of each pocket. This design seems to be common to a lot of cradles. The new cradles don't have these pockets so they can't collect water or sag in the middle. I'll post again when they are mounted and maybe provide a picture.

Posts: 1 | I noticed the same thing and was worried about what damage would occur to my Tiger as I drug it from Iowa to Rick White's sailing seminar, in Key Largo. I solved the problem using four carpet samples, contact cement, and bedding foam material (dimpled on one side). I first cut the carpet sample to size, using the cradle as the template. I put contact cement on the fiber side of the carpet and on the smooth side of the foam. I put the foam in the cradle, cement up (of course) and dimples down (dimples increase the friction against the lined cradle). Then I laid the carpet on the foam, cement down (of course) and edges aligned. I eased the boat down onto the combination. Do it three more times. Result: a perfect pad to rest hte boat on, that conforms to the cradle shape. The foam, against the lined cradle prevents the pad from sliding. The boat sits in a very soft pad, with no gaps. I did more than 3200 miles, round trip, to Rick's class, without any damage. Pretty cheap, too. As long as you get the cement in the right direction! | | | Re: Tiger hull cradles

Posts: 270 Nepean (Ottawa) Ontario Canada | I currently just cut out a piece of 3/4" plywood to shape and put a bit of carpet over it Then another piece on the other side of the support. This is not recommended although no problems but I don't trailer it far.
I am about to make new supports and it just occurred to me to try a new way to make them. I have not figured out exactly how to do it, but essentially I am going to get some wide (probably 2 or three inch webbing) which I will attach at the ends somehow to the frame of the cradle so the boat makes it's shape and spreads the stress out. Somewhat like a strapping used to sling a boat at a boat hoist.
Anyone ever try this?

Posts: 270 Nepean (Ottawa) Ontario Canada | good point hobie1616. <img src="http://www.catsailor.com/forums/images/graemlins/smirk.gif" alt="" />
Maybe spread some silicome sealant on the straps, cover with polyethylene plastic, and then put the boat in it till the silicone sealant sets and then remove the boat, then pull off the polyethylene, so the silicone would take an impression of the hull. This would make the straps non-slip. This might cause some minor chafing?
Or maybe have two straps at each station. Each strap starts at the top on opposite sides, then goes down and part way up the other side where it is attached... Creating a rounded X ... The bottom part of the X would be flattened out... This should stop the fore and aft swaying and lateral swaying.
As fate would have it, I have some old heavy heavy webbing that was used to carry sling loads below a helicopter.
Has anyone tried supporting the boat by the crossbars?

Posts: 105 Bloomington, IN | Here's the solution I arrived at. I did order the cradles from Rick's store that are recommended for Hobie 20 bows. They fit like a glove, the only caveat being that the best location is about 2 feet ahead of the front beam. Farther back and the hull is too wide, farther forward it is narrower. To lower the boat I unbolted the center section of the trailer frame from the tongue and from the wheel assembly and flipped the whole thing. It was a bit of work, but the results work great. The cross beams are very securely welded to the longitudinals, so I don't anticipate any problems there. Oh, and here's a picture of one of the old cradles that shows just how little area was supporting the hull (the previous owner glued on the stupid astroturf - very abrasive stuff - bad idea). ![[Linked Image]](http://home.att.net/~jeffrey.becker/Tiger/OldCradle3.jpg)
