Depends on your level of expertise.
The immediate answer would be an Access database, but if you're not familiar with Access there's a learning curve, and I don't know if keeping these records is important enough to you to warrant climbing it.
The actual database is simple enough, that form isn't so complicated, it just has a lot of info on it. You'd have a table for each 'trip', then a subform for the results of the respective trips. The complicated part would be in making it easy enough to use. For that you'd really want to make a custom form or two, and to make them 'smart' you'd need a handle on Visual basic.
This is possibly why nobody can really answer - hopefully without sounding unkind or rude, if your knowledge of Office and its applications is such that you don't know which app to use, it's unlikely that you're going to be able to do what you want to do even if someone tells you where to start.
If you want to look at a simpler way, you could transfer the form onto an excel spreadsheet, and do it mostly manually. You can add checkboxes to Excel, but again unless you have a grasp of Visual basic, they just going to be dumb 'x's - they will just be on or off.
