Thanks for support guys! It means a lot. Here are a couple of photos of the bowsprit tube installation.

The wooden plates are placed either side of the metal twin bar. Our first idea was to place a sewage drain tube (dia. 110mm) into the round socket of the inner wooden plate that you can see in the image. It would be held there by the big washers (the tube has a bit wider part at one end which normally holds a gasket on the inside). The problem we initially forgot to think about was that the bowsprit isn’t perpendicular to the plane of the twin bars. So we had to make the tube in two parts. The first one is a short ‘ankle’ piece (7 or 15 deg can’t remember any more), attached permanently to the wooden plate. To this short tube, a longer straight one is attached, and this one is removable. The rear end of the long tube is suspendid by a piece of wire from the top of tabernacle. The bowsprit is kept centered to the boat at all times, by the hole in the wooden plate which is just a little bit wider than the sprit diameter. That way, it is not possible to swing it any more, but there is some virtue in having the thing simplified. The plus of this system, which was mostly crafted by my father, is that there is no drilling of the boat. The original setup can be brought back without a scratch. Well, almost – we did one little drilling thing to the bowsprit: there is a black plastic ring at the rear end. It has a wider end which is normally on the rear. We took it off and placed back (with pop rivets) the other way around. That way the wider part serves as a stopper when it hits the wooden plate, preventing the bowsprit to be pulled out of the boat.

There is a potential problem for bridge shooting: to raise or lower the mast one has to remove the long tube. And to remove the long tube, one needs to push (or more correctly pull) the bowsprit into sailing position… This could be avoided if the bowsprit was cut a bit shorter than original, and a shorter rear tube used. There are two more possible excuses for shortening it. The first one is that it might be good to be able to withdraw it fully into the boat when mooring. The other reason is that the bowsprit has a reinforcement inside which stretches from forward end to a couple of inches short of rear end. Perhaps it would be better if the sprit leant against the wooden plate with this reinforced area, rather than with the thinner part… On Pinčika, we didn’t do this shortening yet, because I wasn’t sure how it would affect the sail shape. But after experimenting with the asymmetric hoisted and bowsprit not fully extruded, I believe that a difference of a few inches isn’t noticeable.

Unfortunately I can’t provide more photos now, as the boat is far away from me and I’m leaving for a holiday the day after tomorrow. If anyone is interested I can give some more details when I return.

Also, I heard from Ralph Roberts that he has been helping a French Wayfarer with a similar thing. I haven’t seen any photos of it yet, but he told me that they used a thinner tube (75mm if I remember correctly), and managed somehow to make the thing removable more easily. Weather they shortened the sprit or not to achieve this, I don’t know yet.

Best regards,
