Ice machine for a marina (yacht club / specialty marine)

A marina, yacht club, or fuel-dock ship store is a Specialty Marine ice buyer. Two charts we opened print that row at 3.5 lb per person: The Kitchen Spot’s commercial ice machine sizes chart, and the Ice Machine Sales sizing chart on their ice-machines page. Kitchen Spot’s chart header says add 20% for a safe margin. That is the worksheet. It is not a VenueIce marina factor, and it is not a measured gate count.

The same Kitchen Spot article family already used on sibling pages — Ice Machines: Sizing for Application — prints the same Specialty Marine 3.5 lbs per person cell, on the same chart that carries restaurant 1.5, cocktail 3, beer and wine 1, and hotel guest ice 5. Those other cells stay on their own pages. A yacht-club headcount does not become a country club campus sum (grill 1.5 + lounge 3 + ballroom 2). It does not become a cocktail bar at 3 lb per seat, a beer-and-wine room at 1 lb per person, a hotel floor at 5 lb per room, or a restaurant at 1.5 lb per guest.

Bagged ice for boat coolers is a second line: GoFoodservice’s packaged-ice rule, 10 lb × bags sold, already used on the convenience-store page. Do not fold those bags into the 3.5 lb person line. A dock cart limited by 115 V and a water tank is the food truck page. This page is a shore building: ship store, fuel-dock counter, yacht club bar or galley, dockside snack fountain.

This is a planning page from published application factors and current OEM sheets already in this directory. It is not a dealer quote, not a review score, and not a health-code opinion. Confirm electrical, plumbing, clearance, corrosion exposure, and sanitation with the people who inspect the building.

Who this is for

• Marina ship stores and fuel-dock counters that serve people on a peak Saturday and may also sell bagged ice for boat coolers.
• Yacht club bars and galleys sized on the Specialty Marine person line, not on a golf-club campus sum.
• Dockside snack fountains where the ice is for drinks at the shore building.
• An optional bait or seafood display that actually sits in ice. That well is its own flake line.

It is not a country club that sums dining, a lounge, and a ballroom. It is not a cocktail bar at 3 lb per seat. It is not a hotel guest floor. It is not a food truck. It is not an onboard boat ice maker. None of the models in this directory are a 12 V yacht appliance, and this page does not size one.

Published factors

The Specialty Marine cell is a dealer application rule of thumb, not a manufacturer warranty and not a lab measurement of your dock. We use the cell the charts print. We do not invent a marina-only pounds figure.

Pick one published person line. On this page that line is Specialty Marine 3.5 lb per person. Say which buffer you used. Do not put Kitchen Spot’s 20% on an Ice Machine Sales total that you already decided not to buffer, and do not put a hot-room derate on a 90/70 cell.

Separate lines — do not stack the same person

• One headcount, one 3.5. A member counted at the yacht club bar is not also a restaurant guest at 1.5 lb, a cocktail seat at 3 lb, and a beer-and-wine guest at 1 lb. Specialty Marine replaces those rows for this operation.
• A country-club campus is a different building type. Grill covers, a 19th-hole lounge, and a ballroom each have their own published line on the country club page. Do not add those lines on top of 3.5 for the same Saturday, and do not average them into a house “club lb.”
• Bags are 10 lb × bags. They are cooler ice leaving the ship store. They are not a second 3.5 on the person who bought the bag. They are not added into the 3.5 before the 20%.
• A fountain cup count replaces 3.5 when you counted cups and did not count people. If the cups are a different station serving people who are not in the headcount, keep the cup line separate and say so. Do not run both methods on the same people.
• A bait or seafood case is cubic feet, or a measured fill. It is not 3.5 lb per person again. Cube or half-dice for drinks and flake for a display are two ice forms. Kitchen Spot’s own multiple-machine note is that flake for a display and cube for the bar can be two machines.
• A slip is not a hotel room. Do not multiply dock slips by 5 lb. A lodging wing the club actually operates is the hotel line, and those overnight guests should not also sit in the 3.5 count.
• A food truck or dock cart with a generator, a tank, and no building drain is the food truck page. Power and water dominate that worksheet. A ship store with a dedicated circuit is this page.
• One buffer, from the chart you picked. Kitchen Spot’s 20% (or 10% once that need exceeds 1,000 lb/day) belongs on a Kitchen Spot application, once. Ice Machine Sales does not print a percent on the Specialty Marine cell.

Worked peak day — yacht club Saturday

Headcount below is a planning assumption, not a turnstile reading and not a claim about any real club. One shore building. One busy Saturday. Yacht club bar and galley, members and guests through the lunch and the dock rush. No bags in this section. No bait case. The bag line and the display line are later, and they are not inside these pounds.

80 people on the Specialty Marine row.

80 × 3.5 = 280 lb.

Kitchen Spot’s chart says add 20%. The raw need is 280 lb, which does not exceed 1,000 lb/day, so the 20% margin is the one they print:

280 × 1.20 = 336 lb.

We do not multiply 336 by another 20%. We do not also take a hot-room percent off 336. The hot-room sentence is why the model section uses 90/70 when the sheet has it.

Ice Machine Sales prints the same 3.5 lb per person and does not print a percent on that cell. Their reading of this 80-person day is 280 lb. That 280 replaces 336 if you chose their chart and stopped. It is not 280 + 336, and it is not 280 × 1.20 unless you moved the day onto Kitchen Spot’s chart. The worked line below is Kitchen Spot: 280 raw, 336 with their 20% once.

The same 80 people are one count. A second register at the galley does not copy the 80.

A larger day, still a planning assumption, only to show their 10% sentence: 300 people × 3.5 = 1,050 lb. That need exceeds 1,000, so Kitchen Spot’s prose says 10% should suffice: 1,050 × 1.10 = 1,155 lb. A 20% reading of the same 1,050 would be 1,260 lb. Use one of those, not both. That 300-person day is not the 80-person Saturday above.

What those other rows would do to the same 80 — do not add them

Each figure replaces 280 / 336. It is the wrong row for a Specialty Marine headcount.

• Cocktail 3 lb: 80 × 3 = 240 lb. Kitchen Spot +20% on that cocktail cell would be 288 lb. That is the bar worksheet. It is not this 336.
• Beer and wine 1 lb: 80 × 1 = 80 lb; +20% → 96 lb. That is the brewery worksheet.
• Restaurant 1.5 lb: 80 × 1.5 = 120 lb; +20% → 144 lb. That is the restaurant worksheet. A plated galley lunch does not get 1.5 on top of 3.5.
• Hotel 5 lb per room does not apply. Eighty people are not eighty rooms.
• A country-club sum (grill 1.5 + lounge 3 + banquet 2) is three other counts. It is not a multiplier on these 80.

Bin leftover for the Saturday window

Assumption, planning only: the 280 lb raw line (or the 336 lb Kitchen Spot margin, if you size the window to the buffered cell) leaves during a 4-hour Saturday window — late morning through early afternoon, dock traffic and the club lunch together. Lunch is not a second copy of the dock rush. The 4 hours are one window inside one day. The hourly split below is arithmetic, not an OEM hourly guarantee. Harvest is cyclic. See ice bin sizing.

Manitowoc IYT0450A air-cooled half-dice, directory page: 490 lb @ 70/50, 378 lb @ 90/70. Head only.

• 378 lb @ 90/70 covers the 280 lb raw day and the 336 lb buffered day.
• 4 hours at 378: 378 ÷ 24 = 15.75 lb/hour × 4 h = 63 lb.
• Atlantic’s shape on the 280 lb pull, if the only opening stock is that window’s make: shortfall 280 − 63 = 217 lb. Add the 63 lb of make back as opening safety stock → about 280 lb usable.
• Same shape on the 336 lb buffered pull: 336 − 63 = 273 lb shortfall; +63 lb stock → about 336 lb usable. The 336 replaces 280. It does not sit on top of 280.
• D-570 storage 543 lb, as cited on the banquet hall page from the iT0450 PDF (footer 6478 01/18). This page did not re-measure that bin. A full 543 lb sticker covers a 336 lb window on paper. Kitchen Spot’s 20% usable-loss reading: 543 × 0.80 = 434.4 lb, about 434 lb. Plus 63 lb of arithmetic make ≈ 497 lb, which covers 280 and 336.
• Kitchen Spot’s “bin 10–20% larger than daily make” shortcut on the 336 lb day is 336 × 1.10 = 369.6 lb to 336 × 1.20 = 403.2 lb. 543 lb is above that shortcut and below twice the day (336 × 2 = 672 lb). Their “usually a bad idea” line is the twice-daily bin, not this D-570. Pair the bin only if the head’s sheet lists it. The IYT0450A directory note says this head is not stackable. One head already covers this Saturday.

A 90 lb undercounter bin does not hold this window. This directory’s largest undercounter storage is 90 lb (UYF-0190A and UYF-0140A). Kitchen Spot’s 20% usable-loss reading is 90 × 0.80 = 72 lb. Both miss a 280 lb pull. The 80-person day is a modular head and a bin, not a 90 lb cabinet.

Hoshizaki KM-520MAJ is approximately 556 lb on the product page. 90/70 is not on that page. 556 covers 280 and 336 on the “approximately 556” cell. If you apply Kitchen Spot’s “15% or more” because there is no 90/70 cell: 556 × 0.85 ≈ 473 lb. That is arithmetic on their derate sentence, not a printed 90/70 cell. 473 still covers 336. Do not also subtract 15% from the 336 lb target. This page does not invent a bin poundage for that head.

Scotsman C0330MA-1 is 288 lb @ 90/70. 288 covers the 280 lb raw day and misses the 336 lb buffered day. Ice-O-Matic CIM0430A is 320 lb @ 90/70 on the cited PDF. A later reprint is flagged on that directory page as 310 lb @ 90/70. 320 and 310 both miss 336. Treat 90/70 as labeled if the sheet in your hands is the later one.

Smaller ship store — 20 people, no bags

Same Kitchen Spot method. Planning assumption: a fuel-dock counter, 20 people, no bags, no bait case.

20 × 3.5 = 70 lb. Chart +20% → 84 lb.

Ice Machine Sales, same 20 people, no percent on their cell: 70 lb. That replaces 84.

Assumption: the 70 lb (or 84 lb) leaves in a 2-hour Saturday fuel-dock window.

Manitowoc UYF-0190A on the NEO 140/190 family sheet: 193 lb @ 70/50, 140 lb @ 90/70, 90 lb bin.

• 140 lb @ 90/70 covers the 70 lb line and the 84 lb buffered line.
• 2 hours at 140: 140 ÷ 24 × 2 ≈ 11.7 lb of arithmetic make.
• A full 90 lb sticker plus about 12 lb covers 84 if every pound scoops. Kitchen Spot’s 20% usable-loss reading: 90 × 0.80 = 72 lb stored, plus ≈ 11.7 lb make ≈ 84 lb. That sits on the buffered cell and covers the 70 lb raw window. It does not cover the yacht club’s 280 / 336 lb day.

Manitowoc UYF-0140A is 100 lb @ 90/70 with the same 90 lb bin. 100 covers 84. The bin math is the same 90 lb sticker. Ice-O-Matic ICEU150HA is 130 lb @ 90/70 with a 70 lb bin. 130 covers 84. The 70 lb bin does not: 70 × 0.80 = 56 lb stored, and 2 hours at 130 is 130 ÷ 24 × 2 ≈ 10.8 lb, about 67 lb together, which misses 70 and 84. The bin is the constraint, not the 24-hour rating.

Hoshizaki KM-161BAK is 156 lb with a 78 lb bin. 90/70 is not on that HTML. 156 covers 84 on the “156” cell. The 78 lb bin after a 20% usable-loss reading is 62.4 lb. Two hours at 156 is 156 ÷ 24 × 2 = 13 lb. About 75 lb together covers 70 and misses 84, and that 156 lb/day figure is not a 90/70 cell.

Boat-cooler bags — a separate 10 lb line

Use this when the ship store sells bagged ice for boat coolers. It is not inside the 280 / 336 lb person line. Planning assumption, not a sales report: 40 bags on that same Saturday, and the bag on the rack is a 10 lb bag.

GoFoodservice: 10 lbs × bags sold per day. 40 × 10 = 400 lb.

• The 400 lb does not get Kitchen Spot’s 20% stacked on it. Their Specialty Marine chart does not print a bag cell. The 20% stays on the 280 lb person line.
• Do not compute 80 × 3.5 and then add 400 into that product before the 20%. (280 + 400) × 1.20 = 816 lb is the mistake. The person line with Kitchen Spot’s buffer is 336 lb. The bag line is 400 lb. If both exist, the two worksheets sit side by side: 336 + 400 = 736 lb. The 400 is not multiplied by 1.20 again.
• A person who buys a bag is still one person on the 3.5 line for drinks at the bar or galley. The bag is a different use. Counting them only on the bag line is correct when the store sells bags and does not serve drinks. Counting them only on the 3.5 line is correct when there are no bags. Counting both, as two lines, is correct when the building does both.
• Ice Machine Sales’ summer bag band on their c-store page is a different article. This page does not copy that band onto a marina. Count the bags you actually move.

A ship store whose entire job is bags, with a zero person line, is a 400 lb bag day in this assumption. That is closer to the c-store bag worksheet than to an 84 lb undercounter. IYT0450A at 378 lb @ 90/70 covers 336 and misses a 400 lb bag line alone, and it misses 736 if both lines are real. Two jobs that large are two production questions. This page does not invent a shared-bin poundage for a pair of heads.

Dockside snack fountain — cups replace 3.5

Use the ounce row when the snack bar has a cup count and you do not have a person count. Planning assumption: 120 cups, Kitchen Spot 8 oz ice / 16 oz drink.

120 × 8 oz = 960 oz. 960 ÷ 16 = 60 lb. Chart +20% → 72 lb.

That 60 / 72 lb replaces Specialty Marine for those cups. It does not sit on the 80-person 336 lb. If the 120 cups are a different dock window serving people who were not in the 80, say that and keep the lines apart. This worked Saturday does not include that fountain. A 16 oz cup at 8 oz ice is one Kitchen Spot cell. Their 16 oz ice / 32 oz drink cell would be 120 × 16 ÷ 16 = 120 lb, then +20% → 144 lb. That replaces the 60 / 72 lb reading. Do not add the two cup rows.

Scotsman HID525 is the public-access dispenser in this directory: 500 lb @ 70/50, 380 lb @ 90/70, 25 lb hopper. A 2-hour snack window at 380 is 380 ÷ 24 × 2 ≈ 32 lb of arithmetic make. Hopper 25 + 32 ≈ 57 lb. That is about 3 lb under the 60 lb raw cup line and under the 72 lb Kitchen Spot margin. The hopper is the constraint. It is the wrong leftover for a 280 lb yacht-club window.

Bait or seafood display — only if ice is in the case

A refrigerated bait case, a dry rack, and a closed freezer are zero ice. If the product sits in ice, the line is the volume of that well, once. Kitchen Spot and Ice Machine Sales both print seafood deli 30 lbs per cubic foot display. That cell is not a marina person factor. Planning assumption: 0.5 ft³.

0.5 × 30 = 15 lb.

Atlantic’s display line, already used on the seafood market page, is measure the fill plus replenishment when you can weigh it. The 15 lb figure is the published cubic-foot cell on a half-cubic-foot assumption. It is not a weighed case.

If you stay on Kitchen Spot for both the 80 people and the well: 280 + 15 = 295 lb, then their 20% once → 354 lb. That 354 replaces 336. It does not sit on top of 336. A marina with no ice in a display case keeps the day at 336 lb.

Cube or half-dice stays in the glass. Flake stays in the case. Hoshizaki F-330BAK is the flake cabinet in this directory (331 lb up to, 80 lb bin). It is the wrong machine for the drink plant, and it is more flake than a 15 lb well needs. The seafood market page is the display worksheet when the case is the job.

Ice type

Drinks at a yacht club bar, a galley, or a dock fountain want a cube that dispenses and melts slowly enough to survive the glass. See cube vs half-dice vs nugget vs flake.

• Half-dice or cube is the drink ice on the heads below: IYT0450A half-dice, UYF-0190A half-dice, CIM0430A half cube, C0330MA-1 medium cube, KM-520MAJ crescent.
• Nugget only when chewable soft-drink ice is the brand at the snack fountain. It is not required by the 3.5 lb row. HID525 is the dispenser in this directory.
• Flake is not the drink plant. Use F-330BAK only for a bait or seafood display that is actually a flake bed, and keep those pounds off the 3.5 line.

Form factor

The 20-person ship store (70 / 84 lb) can be an undercounter if the bin covers that 2-hour window. The 80-person Saturday (280 / 336 lb) is a modular head and a bin. A customer-facing dock fountain can be a dispenser with a small hopper, which is a different storage problem. Cooling is a mechanical choice, not a 3.5 lb factor. See air-cooled vs water-cooled and undercounter vs modular vs countertop.

Ice Machine Sales, on the same page as their Specialty Marine row (opened 2026-10-02), describe undercounter production as 50–350 lb/day and modular production as 300–2,000+ lb/day. A band is not a SKU. The 336 lb day sits inside their undercounter band and at the bottom of the modular band. This directory’s largest undercounter bin is still 90 lb, so the 80-person Saturday leaves that class because of the window leftover, not because 336 is an unreadable number.

Current heads already in this directory

Figures are the directory pages, which cite manufacturer sheets. Street prices omitted. Pair a modular head with a bin from that sheet’s compatibility list. None of these SKUs is a marine-series model. See the salt-air note below.

Power, drain, and salt air (what is known, what is not)

Directory electrical figures are the commercial heads above. They are not a survey of a fuel-dock pedestal, a ship-store panel, or a yacht-club pantry.

• Power, from the directory pages, not from a dock. IYT0450A is 115 V, 11.9 A minimum circuit ampacity on the dealer transcription that page cites, 20 A max fuse, and the page says to confirm cord versus hardwire. UYF-0190A is 6 A on a 6 ft NEMA 5-15P. UYF-0140A is 5 A on a 5-15P. Whether the building has that circuit is an electrician question. Uncertain: we do not publish a slip-pedestal voltage, a generator size, or a shore-power ampacity. Do not copy a food-truck tank limit onto a pantry that has plumbing, and do not assume the pantry exists because the dock does.
• Drain and water. Melt water has to leave, and ice-making water has to arrive. Fitting sizes belong on the sheet in your hands. Uncertain: a fuel dock, a floating pier, and a clubhouse mop sink are different installs. This page does not invent a hose length or a pump.
• Heat. Use the 90/70 column when the sheet has one. A closet with no intake air is the Kitchen Spot 15% or more sentence, applied to a mild-condition rating, not a third cut on 336 lb and not a second cut on a 90/70 number.
• Salt air, category only. Manitowoc’s specialty product page (opened 2026-10-02) says its marine ice cube machines are “completely sealed and protected from salt water,” with a stainless steel exterior, internal frame, and bulkhead “to address corrosion concerns.” That page does not list a model number, a pounds-per-day rating, a voltage, or a dimension. Uncertain: none of the directory SKUs in the table were matched to a marine cut sheet for this guide. Do not treat IYT0450A or a NEO undercounter as that marine category. If the cabinet will live in salt air, ask a dealer whether a marine or corrosion-protected cube machine is the right category, and read that model’s own sheet before you size it. This page does not invent marine-model production.
• Filter and cleaning. Ice-machine filter on the ice-maker inlet. See filters and descalers and how to clean. Intervals belong on the machine sheet. This is not health-code legal advice.

What this page is not

• Not a country-club campus. Dining, a cocktail or beer-and-wine lounge, an on-site ballroom, and a pool fountain are separate published lines on ice machine for a country club. Charts do not print a country-club lb factor. They do print Specialty Marine 3.5.
• Not a cocktail bar. 3 lb per seat stays on ice machine for a bar. 1 lb per person for beer and wine stays on ice machine for a brewery.
• Not a dining room. 1.5 lb per guest stays on ice machine for a restaurant.
• Not guest-floor ice. 5 lb per occupied room stays on ice machine for a hotel. A slip is not a room.
• Not a stadium or a concession stand at 2 lb per customer. Event-day campuses stay on ice machine for a stadium.
• Not an off-site caterer. Commissary production and a van stay on ice machine for catering.
• Not a food truck. A cart’s circuit, drain, and water tank stay on ice machine for a food truck.
• Not an onboard yacht ice maker. This directory has no marine 12 V SKU. We do not quote one.
• Not a bag line stacked on 3.5. 10 lb × bags is its own worksheet.
• Not a code letter and not a review. No health-department opinion, no scores, no invented traffic counts, no street prices.

If two sheets disagree, we say so. Kitchen Spot prints 20% on the chart that carries 3.5. Ice Machine Sales prints 3.5 and does not print that percent. The worked Saturday uses Kitchen Spot’s buffer once.
