I want to replace the prisms (they're old, and not in great condition) on Sophie B, but I'd like to get the new ones made before attempting to remove the current ones - time for manufacture; and the fact that the current ones have been repeatedly unsuccessfully sealed to tame a leak, so removing them will be a mission; and that it's winter here all pointing to this decision. I have found a plexiglass manufacturer who is able to mould the pieces, but need the exact dimensions. Anyone? Tom Tom: The previouis owner of my 411 replaced the prisms - I'll check with him to see if he was able to buy them as finsihed parts, or how he went about it. I will let you know what comes back. All the best - I hope everyone has a nice weekend sailing... Geoff, Corazon, 411 #41 |

Tom, the Hamburg based company "Toplicht" has got a good reputation with classical boats. As I am living in Hamburg... in case I could be of any help just let me know. Toni (toge, 38/113)

Thank you! Will check if it's the same as the 411s. I can't imagine that they would have different specs. But nothing would surprise me now!

OK - After much measuring, and with great assistance from Tony (see earlier posts) - I think the attached is a pretty good replica of the original decklight prisms.

I have now had our two pisms custom made at EUR 125 (tax incl) a piece in Germany; I do not have any price comparison, so I cannot tell if this is cheap or expensive. The quality is excellent. It will very much improve the light situation in the head, given the old ones were very dull. They were made waterproof with a layer of rubber between the plexi and the aluminum cover. This layer needs to be replaced too.

Dear Friends, I just ordered two prisms for Vanessa and I paid Euro 120 plus VAT, so I think this is an average price! Fair winds matteo (47/069 Vanessa) |

I finally found time to install the prisms. The photo will help you assess what needs to be done if you change them. I used butyl tape to make the prism itself watertight in its seat. I then placed a new sheet of rubber 2mm on top of the prism, cut to fit the aluminum cover. I then screwed the cover back on, making the screw holes watertight with butyl wrapped around the screws. I finally added a new seam of Sika around the outer edge of the aluminum plate. The light situation below deck is very much improved. Funny enough, the new prisms project nice rainbow patterns to the floorboard when the sun is shining.
