Crack in Transom, Both hulls......

[stringfly]

My friend and I both got SuperVeeR's about a month and a half ago. They have about 20 to 30 runs on them, mostly on Nimh's so not over speeded. Both have outside transome cracks on them. The crack runs across the full transome, centering on the bottom strut bolt. No inside breech yet but has anyone else seen this ? Looks like a molding layup problem to me. Any suggestions ?? And hey Aquacraft, how about a new hull ?????

Looks like they cracked along the seam between the deck and hull. Isn't there a piece of ply on the inside of the transom? That should hold it together...

[Steven Vaccaro]

Is it just the paint? I havent seen it happen on the transom, but mostly the port or starboard side walls.

Most of the supervee hulls do this nothing to really worry about.

I had a crack go all the way in the same location. I was running and the rudder hit some debris and the rudder bracket tried to pull all the way through the transom which resulted in a crack through the transom. I wasn't using a break-away bolt on the on the rudder so at wot hitting the debris all the stess pulled out on the lower bracket bolt . I repaired the crack and starting using a nylon bolt problem solved.

Thanks guys,,,, yes it does just look like the gel coat paint top layer on on the outside.
Not sure about plywood on the inside, all you can see is fiber glass. May be one under that but not sure. The bolt plates are against fiberglass. Don't no of any hits I have had though. Rudder and turn fins are sharpened and no hit indications on them at all. I quess I will just try to run some thin CA in it and keep a eye on it. Does OSE offer the nylon bolts just in case ????

If the boat has plywood on the transom its not the "R" version.

But it sounds like yours is the R

Take a quick trip to your local hardware store, they will have nylon bolts.

R

Mine is the 27R and no ply in the transome that is visible. If I push the strut up or down a slight amount the crack will open and close....not good. I did run thin ca down the crack and let it dry throughly. It does not open now when I tweek the strut but doubt this is going to last very long. Guess we will see. Aquacraft needs to do better on this hull for the cost. Other than this though I still like the boat and the way it runs.

do this bud

strip it and reinforce everything with fiberglass except the top deck area on the inside it will hadle and "crash" better.I relayed mine up and it is way stronger now on the sides and transom where it is weak at the seam.I used a bondo 13 dollar fiberglass kit..done.search the sv section here for other ideas too

Newbie here. Don't mean to hijack this thread but I recently purchased a 27R and have about 6 runs on it. The crack started to form when I ran it today. There was a bit of chop but I wasn't running all out, just cruising. I love the boat. Its quick and easy to maintain but its frustrating spending the money and have something like this happen so quick. Basically, the transom can't take the chop and there was a design flaw there obviously. Oh well, will just have to reinforce it. Can I get something on this site to fix it?

SV pilots

The SVR has a bulker laminate on the transom now and not the plywood. The plywood would shrink and swell between long rests away from the pond causing leaking and what not...

We started testing with a bulker..

sorry some dont like it..

... if this boat was shoe box.. it would do the same thing.. you would just never see it..

Lets race!

What is the bulker? Seems it isn't working out so well.

I think what he meant ot say was the transom is bulkier as in it is more thicker.


That crack is right along where the top half of the hull meets the bottom half.
Come on guys, everyone who has owned a SV in the past KNOWS that these boats are prone to cracked in this area.


Here is a terrific shot of my old boat.
See the crack along the side?
Maybe its not on the transom, but this is exactly where the top half
of the hull meets the bottom half.
There is a seam that runs all the way around the boat.

You know this!!

[Grimracer]

Thanks Z400 for chiming in..

Still got that wicked 1/8 mile monster?

The transom now uses a bulker laminate and not the plywood..

No need to get into details but its a thickener/strengthener that does not shrink and swell from wet to dry.

Past that point its still from the older SV molds so the seam line did not change.

Rocket and roll!
