I am creating a rowing reporting and statistics system for a client where I have a structure at the moment similar to the following:

-----------------------------------------------------------------------------
| ID | Team     | Coaches    | Rowers     | Event     | Position | Time     |
-----------------------------------------------------------------------------
| 18 | TeamName | CoachName1 | RowerName1 | EventName | 1        | 01:32:34 |
|    |          | CoachName2 | RowerName2 |           |          |          |
|    |          |            | RowerName3 |           |          |          |
|    |          |            | RowerName4 |           |          |          |
-----------------------------------------------------------------------------

This is an example row of data but I would like to expand this out to a Rowers table and Coaches table and so on but I don't know how best to then link that back to the Entries table which is what this is.

Has anybody got any words of wisdom they could share with me?

Update

A Team can have any number of Coaches and Rowers, a Rower can be in many Teams (Team A, B, C etc) and a Team can have many Coaches.
