Is this the boat?

If so, very nice looking boat!
Actually, I'm not all that impressed with it. I feel the topsides are out of proportion to the hull (topsides too tall, hull too squat) and those oversize pilothouse windows gave the boat a Walt Disney cartoon look. The bow is too raked for the style of the boat.

Photo 29 has an interesting shaft packing modification.

If someone was contemplating new tanks for a boat I would not recommend stainless
Hendo78,
Wise to be suspect in this matter. I'm no expert on metallurgy but from both my ultralight flying and building days and the boating thing since 1950 I can give you something to consider.
Most commonly there's 5000 series, 7000series, 6000 series and 2000 series aluminum alloy.
Most boats are made of 5000 series and are obviously very resistant to corrosion and fairly strong.
Airplanes are made of stronger stuff most likely 7000 series but could be 6000 for some things.
2000 series is very strong but corrodes very fast. 7000 is strong and hard as well. I've wasted many drill bits on 7000 alloy.
Most 5000 and 6000 series stuff commonly available will probably be good for a boat tank. Others here will probably know more.
As to your tank the problem will probably be not knowing what alloy the tank was made of. When the plate was raw material there will likely be faint blue numbers like 2024, 6061, 7075 or 5052 ect. Lacking that info you may be able to trace back who made the tank and find out from the source. Lacking that you may be able to draw some conclusions from the life the tank has led. Exposed metal, 20 yrs old, chipped off paint showing bare metal that is or isn't corroded ect.
Good luck and let us know.
All that being said, I have two 150 gallon stainless water tanks that haven't leaked a drop in 33 years.
An important feature in my opinion. Non sundeck aft cabin boats, and even some sedan styles like Blue Seas, don`t have enough room aft to swing a cat(apologies to all ship`s cats, time they had their own thread) or for chairs, table, and a comfortable drink or meal. Sure many boats have a flybridge, but getting urgent supplies from the fridge and galley are less easy. And if the cockpit is well covered all the better, in these days of sun exposure worries.The thread was called "What to look for in a Trawler, Eric... In this case I think the attraction to look for being illustrated is the nice rear cockpit space of a sedan...?
Was it the extra length that was the primary problem, ....or the extra draft associated with the longer vessel??We cruised on a 37' full displacement trawler for many years between Lake Superior, the gulf and Bahamas. Along came the grandkids who spend a lot of time with us so we got a 42' boat so they could have their own room.
We found that the extra 5' locked us out of many of the small anchorages on the icw and many of the free docks. Go with the smallest boat you can be comfortable with.
I think this is pertinent as the OP mentioned Florida and the Bahamas.

Fishook,
Welcome and if you are going to be "reading all comments" you're going to be very busy for a very long time. However I assume you meant the comments being made now. Well you'd be sell'in yourself short as there are years of comments available to you that were made in the past that are in the archives. They are about 8 years old and quite likely hold more information than the "comments" that will follow in the next 8 years. We have discussed "to death" many important topics that most here are reluctant to bring up again. So here on the forum the past may be of more value to you than what comes down the road. And you do'nt have to wait for it to get posted. So for conversational "banter" mostly look fwd and for explanations and general information .. look back.
Two full displacement hulls, same LOA, beam, draft and displacement. One with a fantail and the other with a transom.
The fantail will be shorter on the waterline. Resistance will be lower at very low speeds (no wavemaking) but much higher at high speed (once wavemaking begins). The fantail will have less stability (less waterplane area) and probably be more "pitchy" bucking or running in a sea. If the rudder and keel are of adequate area the fantail may be more directionally stable. The transom may be pushed around by following seas, a larger rudder and deeper keel alleviate most of this. The fantail will trim by the stern more as speed increases, the transom will run flatter and have a higher speed capability. The fantail won't bang as much when backing into a wave.
So you never have any condensation in the empty tanks. if they were to be left empty for some period of time?....
All our tanks gravity feed from their lowest points so there is really no maintenance necessary to the tanks as nothing stays in a tank when it's emptied. We've never gotten any water or dirt in the bowls of the Racor filters the fuel runs through on the way to the engines. The tanks were made with large inspection ports but we have had no reason to remove them.
Boat did roll a little when we ran on the outside for a full day in 4plus sea hitting on the beam, but I would say must boats would have done the same..
