Do I understand correctly your crew is far weaker than you and your officers?
If I've got enough armour for myself and the party officers but not enough to stuff the weapons locker, yes.

If I don't have armour for at least myself and the party officers then the boarding probably won't end well anyway, unless I can persuade the enemy ship to surrender by bombarding it with grapeshot.
One solution would be for someone to move the locators around so the player is always generated in front of the crew.
It depends on the deck layout. The one which is typical for a frigate, for example, has two decks side by side, with a couple of ramps between them. You and your officers are on one; if the numbers aren't badly against you, your boarding crew is on the other. So I and the officers will deal with our group, the boarding crew will keep the rest of the enemy occupied for a while, and hopefully by the time the crew are wiped out, the officers and I have finished with our side and can deal with the other group of enemies.
Then there's the small ship, which at this stage of the game is probably the only one you ought to be looking at. The boarding crew are all in front of you and, unless they're tough enough to at least take out one or two enemy crew, they'll be wiped out and then I and the officers have to deal with the enemy as if the boarding crew had never been there in the first place.
Then there's the battleship layout, but you shouldn't be looking at this until you, your officers and preferably the whole boarding crew are well equipped. There's a boat in the middle effectively dividing the deck in two. By default the boarding crew and enemy crew all go to one side of the boat; only if there are too many do some go round the other side. So I tend to go round the other side, take out any surplus enemy boarders who are trying to do the same, then hit the main enemy force from behind while my crew are fighting from the front.
And then there's the two-ship layout where one ship is significantly larger than the other and there's only one boarding ramp between them. This is the one where I make most use of side-step because the crew are all clustered round that one boarding ramp. So, pretending to be Errol Flynn swinging over on a rope, I side-step all the way onto the enemy quarterdeck and again start attacking the enemy from behind. There are usually one or two enemy crew who can't get at the boarding ramp and who are therefore ready to meet me as soon as I let go of the "rope", i.e. have side-stepped to a position where I can drop onto the quarterdeck.
Out of all those, probably only the small ship layout really needs the locators changed. But make sure the player isn't alone - officer locators have to be moved forward as well, otherwise the player is going to be surrounded and killed rather quickly.
