That's irrelevant. It's just the way it is.

If someone is not going to race their Hobie one-design, I cannot understand why they would want to keep a mast with a comptip if they have an alternative.

And the comptip is already heavier than an equivalent section of aluminum mast, so why would you want to add even more weight to it just to stiffen it? More power but more weight at the top, so then you will soon be wishing the mast was bendier again to bleed off that power. The boat will capsize faster, and turtle faster, and be harder to right.

Just get a whole new mast and be done with it. Or at least put a bob on the top.
