    Something like this was the only vague idea I had. Now it seems like the only way to go. Thanks. Let's hope I won't destroy the plug - it would delay the splash for at least a week.

    What I'd do is to cut off the top straight section, leaving just enough straight 60mm for bury for the plug, then cut off at the level of the bottom of the plug. Then use a multitool with a metal cutting blade to cut vertical gaps through the tube at six or eight equally spaced intervals. It won't matter if you cut too deep, into the plug. It should be possible, I hope, to get a chisel between the now-separate tube sections and the plug, with the plug held upside down in a vice, and lever the sections off. Then you will be able to scrape the plug clean and start again.

    That's just it... the said someone just noticed (I have no idea why he didnt't realize this before) that the top has some 400-500mm straight section before it starts to taper.

    This new topmast has a length of 365cm before it slides inside the 130/5mm bottom part.

    Oh, how I wish I had a mental capacity of an organized engineer at least on some days to be able to keep away from these kind of stupid mistakes :/

    EDIT: There is enough mast length to cut away the straight 60mm part. Does anyone have an idea on how to get the glued cap off, now that it's ok to destroy the part of the mast it's been glued to?

    Uh-oh! Absolutely impossible, I'd say. Or should be, if  the Sika is adhering properly.

    60mm will feel pretty thin when you're hanging from it in a bosun's chair or climbing harness, but will be OK so long as the taper below it is quite steep, ie, the 60mm doesn't extend downwards below the plug, but increases rapidly towards the maximum diameter.

    Let's say someone has glued a nylon mast cap with Sikaflex 291i a week ago. If the said someone should need to remove the cap, is is possible without breaking the cap and/or the mast?

    And does 60/3mm sound too thin for the mast top in a 1500 kg boat?

    I think you’re right. It’s probably best to start thinking of a new mounting system.

    Well, yes, a split system can work, but you understand that the pendulum part is different from what you already have? Look in Member's Files>drawings>David's vane gears to compare the two. Is it really worth changing? My vane gear stays mounted and with the blade in the water all the sailing season, without issues. There's no need to take it off and put it back on  frequently if the blade is antifouled.

    do you think a split system could work, if I removed the vane and turret from the gear and set it on the solar arc + made a long and wide enough frame for the pendulum system?

    I'm afraid that my outboard prevents using the RHM system because the motor would obstruct the port restraint line.

    A simple alternative would be to skip the angle on the trailing edge of the rudder, at surface level. You would then have a B configuration above and an A one under the surface.

    For that you have two ways depending if the rudder is glassed or not.
    If the rudder is not glassed you could plane the trailing edge a few centimeters.
    If the rudder is glassed, it is possible to add a small peace of foam to extend backwards the lower part of the rudder.
    The effort on a tab are very low, the power to turn the rudder is provided by the water flow. While sailing, It can be moved by a single finger. (on the Navik where the pendulum is free in rotation and managed by a tab, they had developed an autopilot that was moving the tab with a scale boat 1970 technology servo-command !) . On the view, the engine is the black plastic piece arrowed "Moteur du pilote".
