Hi all,
I want to add some marks to the mast so it is easy to know where to position the boom. I was thinking about painting some marks (or maybe add some stickers and then cover it with epoxy paint). Does anybody had done that? any idea about the type of paint I should use? I can imagine any clear epoxy paint can do the job. Maybe spray can? what about anything different than epoxy, like acrylic paint?
Thanks,
Willy

Use a silver marker pen, it will be there forever.

Nail polish glossy red did the job. FYI it was my wife's nail polish... Smile

Mark your sail instead. A small dot with a sharpie in the luff sleeve cutout will do. Reasons this is better:

1. Using the mast with different sails will put multiple marks on the mast that you'll need to not confuse.
2. Using a different mast with the sail, you'll know where to put the boom.
3. If you make substantial downhaul setting changes for conditions, your "spot" wont move if marked on the sail.
4. It will train your eye to look for the boom in a particular spot for the sail, and you'll mentally develop a more refined picture of what the sail rigged the way you like it looks like, vs simply connecting points A and B from the boom and mast.

If you want a marking reference (I have never used any myself), I think that Peconic Puffin's recommendation of making the sail is the way to go. One more thing to remember is that if you use more than one boom, or buy a new one, the front end may differ in configuration. For example, my Maui Sails boom has a much longer mounting surface than any of my other booms.

"3. If you make substantial downhaul setting changes for conditions, your "spot" wont move if marked on the sail."

So you advocate changing your boom height when you change downhaul settings????

Hmmm.....not sure I agree with that.

Marking boom height is really not necessary. If you sail enough, you will figure out pretty soon where your approximate boom height needs to be set (rig your sail, stand it up on the beach if necessary and the boom should be a little bit below shoulder height). Modern boom heads adjust so easily that if you're off a little bit, you just jump down into the water, bump the boom up or down as needed, and then continue sailing. Plus, the mast will get a little wear mark anyway from the boom head which you can use as a reference mark.

I wouldn't rely on using a mark on the mast or sail for setting the boom height since changes to the downhaul setting, base extension setting, mast foot position, wind conditions, or using a different board will impact your boom height. You're better off figuring out how changing the boom height impacts handling and then dialing in boom height on the fly as needed so you can sail comfortably.

I'd use whatever you have handy. A narrow strip of masking tape will leave a mark for a very long time. I gauge it off of the back of my board.

Most here prefer to rig with the boom roughly in place, connect to board, and lay rig over back end to fine tune boom to preferred gap over end of board.

Some booms tend to creep down in hectic B&J or surf (only friction hold after all) and it's odd how you barely care much until it becomes too obvious, and can't be ignored.

A bit like getting past it, and slowly but steadily losing your marbles. Not obvious till somebody (in the course of a heated argument) calls you a silly old buffer. Shocked (Not that such applies to any of the fine specimens of manhood on this 'ere forum!! Wink )
