Hi all,

My centerboard on my MKIII Enterprise will not stay in the position i set it, no matter what sort of pipping i attach to the center board itself and no matter how much i compress it.

I have been recommeded "Jap tape" to pack the centerboard casing. I have ordered some but am not sure exactly where it should be applied? I am presuming to the casing not the board. How should i go about this ?

Thoughts and suggestions appreciated!

Regards

Ben

Try fitting a downhaul rope (part of which can be elastic to allow for movement in case of dragging on the bottom in shallow waters) to the centre board top/handle and feed it to a secured to a cleat on the side of the center board casing.

Is that class legal and an Enterprise?

Thanks very much for the comments folks. Not sure whether it is class legal , however - it wouldn't help too much when i want to secure the centerboard half way up. Do you have any experience of padding the casing ?

Never sailed an Ent, but presumably it's a friction system? I've used Jap tape on a Contender, it works very well applied to the board - I've never tried sticking it onto the case, it's much easier to get at the board to do it. You may need a bit of trial and error to get it right. Start with a short 3-4" strip each side of the board somewhere a few inches out from the pivot. A 2nd strip may help if it's close to being OK with one, or if it's really loose a 2nd strip on top of the first. If it's that loose you are probably going to have a better long term job by increasing the width of the top of the board a bit. I've seen it done very neatly by putting tape around the edges of the top of the board, sticking up slightly, to create a lip. If you then pour resin onto the board and leave it horizontal - the resin will flow and add a bit of thickness across the top of the board. Clearly you need to judge the amount you need to add fairly carefully or you will end up doing a lot of sanding!

Or try packing the case with this stuff http://www.ovingtonboats.com/products/69 - http://www.ovingtonboats.com/products/69 .

It can be shaved down if too thick.

Looks like an interesting alternative to Jap tape

Otherwise available as the fluffy side of velcro strip...

The old hosepipe as friction brake must be capable of working, but you do need thick enough pipe: a really heavy duty rubber hose is what's required, but I'm not sure where you'd get it these days. Some sort of specialist supplier I guess.

Try a farm suppliers who supply milk machine pipe. Quite thick rubber type material or of coursea dairy farmer (there are a few left) you only need a few inches and they have to change it regularly for hygiene reasons so lots lying about.

If you are not rural I can find a short piece and post to you.

PS How wide is the C/B case. I will have a look at the farm when i am milking at the weekend

us deviants in the B14 fleet refer to that stuff as "Polar Bear Pubes". Conversations are then held in the boat park about trimming pubes.

Whatever happened to removing the centreboard bolt and packing the gap between board and case with discs (with holes in the middle for the bolt) cut from milk cartons??? That's what I used on my Ents....cheap and dirty....just how I like it!!!!

Radiator hose from a car spares shop. It is softer than plastic hose pipe. Cut a piece out from the top edge of centre-board about 2.5 inches. insert 2 x 2.5 inch(approx) screws through the hose splaying it out beyond the width of the board. Adjust tightness of screws to suit friction.

When I say radiator hose I meant heater hose about 3/4 inch diameter
