Ribeye S650 minor hull damage on launch/recovery.

We've launched/recovered our new Ribeye S650 about 7-8 times now, mostly without incident.

A few weeks ago we noticed that after one trip out we had a couple of small chips in the gelcoat on the very bottom of the hull, and another on one of the chines along the side.

Couldn't work out what it had managed to catch against, but just hoped that it was a one-off incident.
Unfortunately, after the last time we were out, we noticed another three chips along the chine on the right hand side of the hull, close to where the previous damage occurred.

Has anyone any experience of this, or any ideas what might be causing the damage. We are very careful when both launching and recovering and there's nothing obvious that we can recall.

Also.. I've got some Plastic Padding "Marine Filler" and also "Gelcoat Filler". Which is the best one to use for such small chips?

I've attached a photo to hopefully help show where the damage has occurred.

Hard to tell without a better look, a possible explanation maybe air voids on the rails - saw a Zodiac with this recently - it was riddled! either that or your rollers have had a bite out of your hull! Gelcoat filler sounds like the one to use - make sure it's dried out properly and take a little dremel or something to grind out the hole for filling first.

Sorry you've got a couple of nicks - can they be left unrepaired or does further damage result?

I have used the plastic padding filler that is for gelcoat repair (assume its the same stuff one large tube and one little tube of hardner)

Once you have filled the chips just use some sandpaper to smooth ou the repair and then if you use some very fine wet and dry (1200 min pref 2000) use it wet and you will bring back the shine.

THe repair I did was a gash near the bow eye on my previous rib and you would never know it had happened.

I too have used the plastic padding stuff and achieved good results using the method described.

If these are "air bubbles" on a new hull would people see that as normal - or the responsibility of the manufacturer to put right? Would you at least keep them informed so that if it turns out to be riddled with them you don't have any "well you fixed the first ones yourself" type objection from them?

I would guess those gelcoat chips are coming from the edge of the aft rollers. Gelcoat has no real strength and that chine is pretty sharp. You could switch from rollers to bunks, that might solve the issue. I am guessing patching with more gelcoat will just lead to more chips next year. An epoxy filler might provide more strength against the roller edge.

Do these chips run the whole length of the boat or are they just concentrated around an area a fixed distance from the bow?
If it is the latter, I would agree with the comment above. As you recover, depending on the angle of boat to trailer, if the rear set of rollers are not meeting the hull at the same angle before contact, it could be hitting another part of the rear roller assembly causing the damage.

I bought a new Marshan from the factory back in the late eighties and the gel coat came out in air bubbles but when i informed them we agreed for me to use it for the rest of the season and after they gave me a new hull with no problems afterwards

Can't be bad, wish everyone had this train of thought.

Any honest manufacturer would cover that under warranty anyway - it is a manufacturing fault!

Thats what I mean, not all are quite as honest as they should be though.

if it's brand new take it back, but before you do make sure they're going to do it free of charge and then go all over the boat gently tapping all the sharp edges you'll find more i bet

If I really thought that it was a fault in the moulding then I would, and I'm sure that the guys at Ribeye would sort it.. but I'm not convinced.

I've also noticed some even bigger chips along the very bottom V of the hull, and I think that the boat is actually hitting against the trailer when recovering (or launching).

To me, it looks like it's probably hitting against the cross members of the axles, before it gets a chance to lift back up onto the front rollers.

Anyone got any ideas on how I could stop it doing that?

I'm having the same problem with my Ballistic on a Rollercoaster trailer - i.e the bottom of the keel is hitting the axle before it is lifted by the front rollers. I've tried a keel roller on the axle but it ends up being too high and almost all the boat's weight ends up on it and chews up the roller. I'm now trying an extra cross-member with lower side rollers just in front of the axle - I'll try and post picies tomorrow of what I'm trying in case it helps.

See my comment No.11
It looks as though you are going to have to move or modify the position of the rear rollers. Without see the boat approach the trailer on recovery, it is difficult to make constructive comments, without making it worse. If you could, get someone to film a recovery and post it on here, that way we can see what is going wrong.
You might look a raising the height of the rollers or moving them slightly more inboard to give the boat more height above the beam. If it is part of the roller support which is chipping the gel coat, see if there is any material you could cut away, without weakening it.
