40 gallon utility tank for a work boat. This tank measures 24x21x19 in .188” 5052 and cost $931. #fueltank
A pair of twin 126 gallon 1996 Cape Horn 27 tanks. These tanks measure 50x42x19 in .188” 5052 aluminum and cost $2055 each less a 10% discount for ordering 2 identical or mirrored tanks. #capehornboats #capehorn27 #fueltank
The tapered belly tank, narrow at the bow and broadening up and changing depth at the stern. 6 bends, all unparallel with the centerline to maximize capacity and fit to the hull shape. We started with the customer’s wood mock-up dimensions, adjusted the design for metal bending, and knocked it out with perfect fit up and weld out. This tank measures 81x30x8 in .188” 5052, holding 52 gallons, and priced at $1747 plus about $340 to ship to Texas. Customize your tank and get instant pricing and checkout on our website in less than 30 seconds. #fueltank #marinefabrication #aluminumwelding
XL casting platform with custom cage. 30”x30” deck, 18” tall. Powder coat white with tan/black EVA deck and rod holders. This project cost was $2020 @marine_mat from @lightnin.jack #castingplatform #sightfishing #redfish #bayboat
132 gallon tank for a Sea Ray boat heading to Georgia. This tank measures 58x24x24 in 3/16” 5052 with 2 pickups and 2 returns. The price was $1756 and $215 to ship. #fueltank  #searayboats
An interesting pair of 250 gallon fuel tanks for a Charleston sportfishing boat. These 2 tanks are split to allow for install (original tank had to be cut out) and they bolt and plumb together to add up to 503 gallons total. The cavity was laser scanned and tanks designed to maximize fuel capacity, hence the complicated shape. The bill was $7900 for the tanks and about $750 to ship. We have instant fuel tank quoting on our website whether you need 5 gallons or 500. Try it out! 🔥 #fueltank #sportfishing #charlestonfishing @rhodesyachtdesign
2 commercial diesel tanks heading to a tour boat in Hawaii. These 150 gallon tanks measure about 72x23x23 from 0.250” 5052 and cost $2626 each. We developed the engineering drawings for USCG MSC approval and they were inspected during construction and pressure testing by our local USCG station. #fueltank
A trio of our customizable rocket launcher rod holders fresh from powdercoating and ready to ship. Customize your dimensions, rod holders, finish, and mounting easily with instant purchasing on our website. #rocketlauncher #rodholder #fishing #customboatsdaily #marinefabrication
Switching gears to a beefy 12 gallon portable tank made from 1/4” 5052. Direct fill with a billet machined vented cap and direct read gauge. This tank cost about $700 plus shipping. #fueltank #aluminumwelding #marinefabrication
We’re entering the Lake Powell houseboat toy tank capacity race. These twin 500 gallon tanks are 72”x60”x28” and made from 1/4” plate at a price of $4520 each. You need a lot of gas to run the new wake surf boats for a week and apparently many of the fuel docks have closed down, so you have to carry it with you! #fueltank #houseboat #lakepowellhouseboats #lakepowell #toytank
A big ol custom diamond plate hatch assembly. #boathatch
