Bow Roller for Rocna

[Matwill]

Hi Guys,

Does anyone know of an off the shelf bow roller for a rocna 10 for a 30 foot boat, im looking for one that locks the fluke when its in the roller, the same as the one in the picture

I had a couple turned for me, with a groove the width of the shank in the centre. The rollers that came with the boat were a shallow curve, across which the anchor slid on every tack.

The original rollers looked like nylon but my replacements are acetal.

I had my roller custom made, I have a Knox, from a manufacturing point of view it is not economic to do this sort of kit for off the shelf.

I purchased an off the shelf tilting bow roller. Used a wooden wedge to jam the rocna in place. After a season I modified the bow roller by making a new roller from a 75mm diameter nylon rod and moving its position. The anchor when fully home is now wedged in place on the rollers without having to use a wooden wedge.

I used a new roller on the pin and then a double thickness 18mm ply profiled block to stabalise the stock which is not fixed. Very easy to lift on and off.

I have something similar to the ideas above except I also wanted to secure the chain when the anchor was deployed - so its a chain lock and a (anti) wobble plate for the anchor. The 2 side slots fit the roller assembly and the centre slot secures the chain and stops the anchor wobbling ( was worried that the constant wobbling would abrade the roller).

Its made from 5083 aluminium, as is our bow roller. You need some aluminium - but it could equally be nylon or ply. If its aluminium you need an angle grinder and the thin discs they market to cut stainless steel.

The right hand slot is that funny, enlarged, slot as there is a weld in the bow roller and the slot needed to clear the weld.

The string is used to lash it down and make sure I don't drop it overboard. You could make yours less obstructive than mine.

I have a friend who simply made two nylon wedges, wide at the front. and as the anchor was received the anchor was forced between the wedges. simply attached to the sides of the bow roller with appropriately sized bolts.

Your bow roller is very spiffy and I'd not want to drill it - some sort of drop in comb device, like mine, but in polished stainless (winter will arrive sooner than you think - you will have plenty of time to polish . )






I don't have a picture of the wobble plate in use at anchor but this is the complete bow roller (it supports the cross beam and forestay attaching it to the bridge deck). The wobble plate slips down between the end of the beam 'this side' of the roller and locks again the roller


Simple stuff
