Lazyjacks and Selden boom

[gasdave]

I have a Selden boom with single line reefing (2 reefs) and am intending to fit lazyjacks.

Can anyone reassure me that there is enough space inside the boom for riveting the lazyjack fittings to the sides without risk of snagging the internal lines, etc.?

I would guess it ought not to be problem, especially if I'm careful with my drill bit. However I do note that the Selden rigging guide does advise against attaching fittings to the sides of these booms!

our lazyjacks on a 2 reef selden boom are secured to eyelets in the track under the boom, the same track as the mainsheet blocks. We do have a cleat to time them off screwed to the side of the boom with machine screws about 200mm from the mast end of the boom extrusion. It doesn't seem to affect the operation of the internal sliding blocks.

I fitted my lazy-jacks in similar fashion to ytd, except that my cleat is also on the underside. The reefing cars fit quite close to the sides of the boom and I can understand Selden's advice. Note that 200mm from the gooseneck end is probably beyond the range of movement of the cars, so won't interfere.

What might ease your decision is to open the end of the boom and take a gander at the internal cars and lines, to judge the best position to insert fixings. I would favour short head rivets for your purpose rather than screws since they will hardly intrude at all, but sharp screws might snag on the lines.

If you do remove the boom end, lower that end of the boom to the deck and have a blanket
underneath to catch any of the car bearings that falls loose - they're easy to reinsert. From recollection, on my rig the middle of the boom profile would be the best place to place your fixings, but check it out.

As above by YTD
Selden boom supplied by them with complete Selden rig including lazyjacks (when you buy a Finnish boat there are not too many extras) with two sets of eyes riveted into track (both sets actually about 300mm too far back to best catch a fully battened main, thought it works) and a pair of cleats at the forward end on the side of the boom. I don't use any blocks as there is very little friction in the system as Selden supplied it and the lines are long enough to allow the whole shebang to be stowed in front of the mainsheet horns when sailing or stowed, so we only deploy the lazy jacks briefly to catch the sail at the drop.
For my main which has a 4.5m foot, a simple two part arrangement works fine (perhaps helped by full length battens). The rear eyes would be better about 1m. from the boom end with the forward ones just behind the vang.
You need deep eyes with very narrow feet as the track groove is narrow but deepish.
