74 Starcraft Mariner 21' Project

[novanglus422]

Hi All. I'm new here, but getting underway with a restoration. Here's a couple pics of where we've been and where we're at, to give you a sense.

Lots of questions as I go along, but here's a quick one. There's definitely a leak at the seam between the transom skin and the hull. Transom will be replaced, but I'm wondering about this leak (plz see pic; leak is from seam where all the crud is). Will I just need to tighten the rivets?

Thanks in advance!
