keel rollers are being trashed

Black rollers have to go.Get the blue ones, as mentioned previously.

White Pointer,

Does that apply to an tinny? I thought it was best to keep the weight of the boat through the keel & on to the center rollers, & adjust the skids so the keep the boat from tipping over, but without any excess weight bearing?

cheers, HR

G'day,

Tinnies and plate boats belong on skids and 'glass boats belong on rollers - lots of them.

Tinnies REALLY belong on skids because rollers dent them and that reduces hull efficiency. Plate boats don't suffer so much because a 5mm hull is pretty rigid.

A single keel dual roller can help align the boat but once up on the skids it should be redundant - nothing resting on it.

I see lots of ally boats on rollers and I've had a few chats with owners about them. Most say that it makes launch and retrieve easier. The solution to this is a bit of silicone spray which makes skids as slippery as an ice rink.

Don't grease rollers. It just creates a mess and pollutes the water at the ramp.

Trailer set up is everything and its hard. I'm still working on mine.

Regards,

for a tinny rollers down the centre skids on the sides

put boat on trailer drop skids down set up the centre rollers so all in position, some boats have a keel that dips down at the end

get someone to hold boat level till while you bring the skids up till they just kiss the hull, when you strap the boat down it will pull don snug on the skids

works fine for me boat slides off with no pushing needed no dents no marks from the skids.
if you dont clean your skids or the boat is too tight on them you get a salt build up on the skids as you cant wash them properly and each time you launch retrieve you mark the bottom of the hull, some tinnys are only 1.6mm thick on the bottoms

Thats pretty much the method I used to set up the trailer.and it all works sort of ok, except as the boat is coming up,it tends to lay over a bit putting the edge of the keel into the roller.
I take the point that these black rollers are the wrong type. And Ill replace them.
Im just concerned that the keel edge will stuff the blue ones as well .Or are they hard enough to take that pressure. Do i need to keep the boat flat on its keelson to prevent the damage.
as I said the rollers are only a few retrievals old.
Cheers

I have had quite a few aluminium boats both pressed and plate. Whilst generally red rollers are fibreglass and blue are aluminium and in a lot of circumstances the blue are fine. Years ago I had a similar issue and tried aluminium rollers. I don't like them for various reasons. In the end I got onto a company called Steadfast Marine. They are based in Sydney and you can google them for contact details. They have a grey very dense nylon keel roller which is better than the blue rollers and will last longer. Unfortuntely all rollers will with alloy boats get some common wear line where the boats rubs whilst it is travelling.

Hope I have been of assistance.

G'day,

Like I said, I'm still learning mine but at 6M long and with 400 lt of water ballast in the hull I find it still lays over a bit to Starboard driving on to the trailer. And I weigh nothing!

I've learned that not sinking the trailer too deep and letting the the boat sit against the rear-most rollers with just too little throttle to mount them tend to square it up and I'm getting better at it.

Not suggesting that this is your solution but that you should experiment with trailer depth - possibly with someone else at the wheel and you watching the roller engagement so you can see the problems.

Sometimes the trailer is impossible to adjust to the boat. I've been there.

Good luck!

Ours uses white nylon rollers that are rock hard but work a treat and are supposedly self lubricating. I'm of the opinion that a tinny should have all it's weight supported by the keel rollers and the skids are just there to stop it tipping over. If you have too much weight supported by the skids you will dent the hull against the ribs.
