    Hello,

    I am having a survey done in a few days on a Bertram Motor-yacht. I would like to know from any Bertram owners any issues to pay attention to on these types of boats.

    Thank you,
    Scott

    We have a '78, 58'.

    What Bert are you looking at? Palatka?

    I hate the un-treated plywood frames for bulkhead and frames.
    The plywood starts to fall apart and the fibers come off like fur.
    Look under and behind every bilge plate and panel.

    144 inch long single piece, 2 1/2" shafts. You should find a spare shaft carrier in the stb transom, below the water line.
    Maybe even a spare shaft. If she list 3 degrees stb at rest, you have a spare. Only 1 degree to stb, no spare.
    The 58 MYs always list to stb.

    I had to install valves between the aft water tanks. Water management at first but it really helps to keep the boat level.

    Fuel tanks are bomb proof. Fuel and fill hoses suck. Examine carefully.

    Don't be scared of a 32Vdc system.
    Please do searches on past YF post.
    We have all talked about this for years.

    You may have 2 shore power cords on each hull side. Originally a 120Vac/50A and a 240-120Vac/50A.
    The 120Vac only are for the lights and chargers. the 124-120Vac is for the heavy appliances (ACs, Oven, etc).
    I have converted to dual (on each side) 240-120V/50A connects and slowly updating my breaker panels for power management.
    We also have 2 gen-sets, 2 water makers, dive compressor and lots of power hungry items.

    If it still has the old Detroit gen-set, plan on canning it.

    Balsa coring in the forward fiberglass flybridge coming is usually wet with water. Somebody else made it for Bertram.

    Many, many thru hull sea cocks, some hard to reach.
    Bertram luved punching holes for EVERY in/out hose.

    ALL SOLID GLASS HULL. Very heavy. Very deep V hull. Lots of wet surface. NO MPG.

    They consume fuel. If your rich and famous, I need to meet you (long lost rich cousin).
    Or else, plan on 7 to 10kts cruise.
    But when you need to go fast or power thru an ugly inlet, nothing is better.

    These pigs also make great surf wake. Your going to do 5-6 kts (or slower) in the skinny St Johns and populated ICW, to keep the shot guns from coming out.
    Kona Pipeline is nothing compared to the tube waves you make at 22+kts.

    Nice. That is exactly what I was looking for. I knew I wasn't going anywhere fast for long. Looks like one Gen was switched out for an Onan 20KW. The secondary 120v looks stock.
    I like the idea of using the water tanks to fix the list. One of the previous owners put granite in the galley and heads. She has a significant list to starboard and it is only going to get worse since the port side has a 35in tube television that will be replaced. (not looking forward to that). I will look for that spare shaft.

    If all goes well with the survey I have hired a captain to take us nonstop from Panama City Beach to Key West. This will give me some time to get oriented with the systems. I have always wanted to visit Fort Jefferson going to spend the night there and then to Islamorada, WBP, Canaveral, Palm Coast or JAX, Paltka, and new home Sanford/ Lake Monroe.

    We did Fort Jefferson a couple of years ago from Jax.
    Down, thru Lake O, Tortuga's, Keys, Fl east coast and back home to Jax. Lots of fuel but near worth every gallon.

    We frequent just south of Palatka and get stared down often. By the time you get to Lake George, you may have been flipped off a time or two.
    You will be at near idle south of Astor or in somebody's sights.

    These ole girls were based on the mighty & fat 58 fish boat hull. Very deep V.
    Rides great at speed. Makes waves running any speed.

    Call ahead to GeorgeTown fish camp on Lake George's north end.
    Cheapest diesel in the state.
    You will want to top off there before Lake Monroe.

    With a 15 degree deadrise, not really in the "deep" - vee category, more like a 'moderate"- vee hull.

    No, she is not a 21 x 8 foot deep V with 20 degrees deadrise in da butt, she is a 58, close to 17 feet wide stern, that's a V butt.
    And it requires fuel to move.
    Usually you would find near flat butts on Hatteras & Vikings, Ole Berts still had a V in da rear.
    For a any 58 x 18, that's a Deep V.

    Yes, I see the Modified V comment.
    I've shown you mine;;;;;
    Your near my LOA, what's your ships rear look like. :D

    Send us some pics. I was not aware a 58my was on the market out there.

    The Vikings of that era ran 15.5 degrees deadrise and their Motoryachts were at 15 as well. The Hatt’s were the flat “butts” but had deep forefoots and deep keels. The later Viking MY’s ran up to 19 degrees.

    The deadrise angle is part of the story as is the chine submersion at the transom, you can see it from the amount of bottom paint from the chine at the transom to the waterline . That is the “deep” part, but you know, a 55 Hatt Convertible of that era is just about as deep in chine submersion and will throw an impressive wake as well, even with a flat “butt” deadrise of less than a couple of degrees.

    Nice pics!

    I luv to learn new things.
    Thx.

    BTW, Our ole Bert was 40 last month.
    That would make the OPs boat 42 years old.

    We still have butt & still kicking butt. Vs, chines and all...
    Bertrams rule..:cool::cool::cool::D:D:D

    Love the name. Say "Hi" for me -- to both of them. I haven't been aboard a Bert 58 in many years, but they sure are grand old ladies.

    The great thing about the Bertram hull is that they will take on more seas than you can imagine, there is a lot of confidence in a 58" just eating up the miles, a true "road warrior" :)

    You were hobbling around and could not make the docks when we came thru.
    Next time.

    Well, Just before a squall line, we found our new sister ship of the St. Johns.
    Scott has brought his new ship all from Panama City FL, thru 10 footers in the Gulf, thru the locks and as perfectly timed, we found each other off of NAS Jax.
    Sadly the weather was about to come down on us and could not raft up. Scott was also on a time frame to make the north end of Lake George tonight.
    I'll find him and his new Bert 58 MY in Sanford FL in a few weeks.

    Darn these 58MYs look good. Not to bad for a 42 year old design.
