324.40111
(2) Except as otherwise provided in this part or in a department order authorized under section 40107, a person shall not transport or have in possession a firearm in or upon a vehicle, unless the firearm is unloaded in both barrel and magazine and enclosed in a case, carried in the trunk of a vehicle, or unloaded in a motorized boat.
This is MCRGO's take on this, in pertinent part:
It is more difficult to say whether it is legal to carry concealed in a boat. Your CPL authorizes you to carry a concealed pistol anywhere in the state, “except as otherwise provided by law”. Michigan law, MCL 324.40111(2) states, “Except as otherwise provided in this part or in a department order authorized under section 40107, a person shall not transport or have in possession a firearm in or upon a vehicle, unless the firearm is unloaded … in a motorized boat.” Similar statutes outlaw the carrying of a loaded firearm in an ORV (MCL 324.81133) or in a snowmobile (MCL 324.82126(1). These statutes were designed to stop poachers from shooting game from a motor vehicle, motor boat, ORV or snowmobile. But, their terms do not limit enforcement to that situation.
The DNR has issued a written guidance to its officers not to enforce the above statutes against anyone with a Concealed Pistol License unless the person is using the handgun to hunt from a motor vehicle, boat, ORV or snowmobile. This has not been formalized into a “department order” so it does not control anyone but Conservation Officers. There is no such barrier for any other peace officer. A police officer or deputy sheriff could arrest you for violation of the motor vehicle, motor boat, ORV or snowmobile statute. I believe that the carry concealed statute was intended to supercede these laws. But it did not do so explicitly. Hopefully the legislature will correct these contradictions.

MCL 750.227d defines vehicles for land travel (other than a pistol) and does not apply here. IMHO, a CPL is required for OC and CC in your boat. And, as listed above, it appears the DNR will not enforce the statue (324.40111) if you have a CPL.
Hope this helps Rugergirl and welcome to OCDO.
