What makes you think they need replacement? What boat and where are they(rivets) located.I do replacement  and tightening of rivets. depending on what boat and what needs removed to get to the rivets.

Bobby Bass - I'm in the 7 county metro, but I'll take it anywhere...great boat.

Sport boats are known to have thin skin, compared with todays alum duck boats.. mine is a 1956 (I think), and heads of the rivet have worn smooth to the alum skin.  Thought I could find a good riveter have a few ribs riveted over winter so it is good to go!

any help would be appreciated

1956 wow they should be exposed rivets or am I wrong? no floor covering on the boat right?easy access to all sections that need new rivets. With you uptop holding a backer we can do the job easily.How many rivets and where. I can do it and have all rivets on hand. Communcation is up to you here.I believe my email is in my profile.one thing tho a more steady average temp might be in your favor.warm expands  the light skin more so than a solid rivet, cold shrinks, best install is a average temp.I live 15 miles east of Wllmar,Mn by Atwater. I,ll check my profile to see if eamil add is there,Or just give me yours.I bet I,m 1/8 cost of a shop 30 bucks per hour with a 2 hour minimum plus parts.With this I need someone up top to back the rivets,Same charge you,ll have to pay your self for the labor charge
 I,ll bet the skin on that boat is heavier than todays boats.Grumman was built to last!

I got your email and I dont believe you know the extent of replacing mulitple rivets.You mentioned we can get er done on Sunday.
 The process follows,tightening old rivets is fairly simple>just rerivet them,Replacing a few is fairly easy,Grind em off from inside the hull,punch em out and replace one at a time.
 With multiples you can only remove a few at a time,So the 3/16 inch holes stay aligned.Then on the keel where a keel and two sides of skin meet along with the ribs that supply hull support.That takes a certain length rivet,Up the rib where the rib gets riveted to the skin requires another length rivet then where skin meets skin another legnth rivet is involved.
 Removing a whole rib worth of rivets doesnt work aligning the holes requires lots of awls if you can even pull the alignment together! So replacing everyother rivet has its merits Then going back and replacing the other rivets.
 Lots of stuff some dont consider and if  all goes well  about 15 20 rivets per hour can be installed.first from the inside the rivet needs ground off with out removing any material or as little as pssible from the KEEL"RIB or SKIN to keep structure integrity,Drilling wont work because center can t be determined and a offset hole will be made that lets the skin move just abit and will leak down the road. Lots of things involved to do it right the first time.
 Right now I am healing from a major surgery the 17th I may have some restrictions lifted. I never thought you wanted it done right now,My garage has winter projects waiting for me,Including 5 outboards'which wont get any attention till ice out.My boat and motor stuff always waits till spring.
 If you want to wait I suggest to save yourself $$ grind every other rivet off from the inside of the hull and we can take it from there.You'll save $$ and see what its like and how long it takes to remove the rivets.Aint easy or quick for a good job to be done.I do back up my work

 I'll add the model of the boat to determine keel,rib and skin thickness would help to determine rivet legnth. Also a verfication of rivet diameter.Most boats I've done since 1987 have all been 3/16 however a old crestliner was 1/4 inch.I did quit doing boat rebuilds the profit margin was ziltch!
