    Rigging ages fast. If your sailing with a rod package, you must inspect and replace. Look for any signs of corrosion..rust bleeds .

    Rod is cheap...cheaper than any sail on the boat.

    Under power, the powerboat will consume about HALF the fuel as the sailboat for displacement speeds, because the powerboat will weigh half as much (no rig, no ballast), and the powerboat will also have substantially less wind resistance (no rig).


    This is not a realistic set of assumptions/

    For "cheap" living the boat will be a very used boat not a special built boat.

    Most sailboats can get 6-10 NMPG as they are true displacement hulls and do not have oversized engines .
    The ones with full keels that can spin an 18-24 inch prop will have best fuel use.

    A power boat of the "same" size will be vastly more windage unless comperable interiors are chosen, say a 35 ft sailboat and a 25 ft power cruiser.

    The engine in the power boat will usually be larger in any size , so less efficient at displacement cruise speeds.

    IF LOA is the consideration most power boats will be 2x the interior volume and are happy to get 3-4 NMPG .

    The budget cruiser will probably install the best set of ground tackle and retrieval gear he can find.

    Marinas in FL are $2 to $5 per foot per night , BIG anchors are a good investment.
