I got the tip from some high-end dingy sailors, that they gave better wet line grip than any other glove. Simply clip the finger tips where you like - because the tips are rubber coated, they won't fray.
I have carpal tunnel problems and grip problems, so for me they are a god send. They have shortcomings:
* They don't wear well. You may go through several pairs a season. Trimming hard and letting the rope through your hands they may not last a few races. Who cares.
* They grip too much... sometimes. They can't be beat for hauling an anchor line or jumping a halyard, but coiling line and delicate trimming require a bit of re-learning. A lighter touch.
* They're not cool looking...
* A touch of gas or fuel ruins them. Give them the pitch.
but on the plus side:
* They are cool.
* They are cheap. Perhaps $5.50, but free from the office

* Plenty for visitors.
* Good for fishing. Who would want to land a bleeding fish with high $$ gloves? The stink lingers in leather but rinses out of these.
Also, if you visit a commercial fisherman's store you will find they make 2 progressively warmer models for the winter. Not cool. Leave the fingers in.
After using these for a bit I gave all my high-end gloves away. I did keep the nice Gore-tex winter gloves!
