Refund Policy
Easy Returns We've taken out the hassle of returning an item so you can shop with confidence. If you need to return an item, we'll provide you with a pre-paid UPS return label that you can print at home. The cost for using the label will be calculated and deducted from your refund.
To start a return, please contact us at sales@theyachtrigger.com. Items sent back to us without first requesting a return will not be accepted.
30-Day Return Policy We have a 30-day return policy, meaning you have 30 days after receiving your item to request a return or exchange.
Eligibility for Returns To be eligible for a return, your item must be in the same condition that you received it—unworn or unused, including tags, instruction manuals, warranty cards, and in its original packaging. You’ll also need the receipt or proof of purchase.
We reserve the right to refuse returns or assess additional fees at our discretion if:
- The merchandise is missing parts
- The item is not in new condition
- The return is beyond the accepted return dates
Return Shipping & Restocking Fees
- Customers are responsible for return shipping.
- If you request The Yacht Rigger to provide a shipping tag, the shipping cost will be deducted from your refund. No international return shipping labels will be provided.
- A 3% restocking fee will apply.
- No returns on final sale items.
Damages and Warranties Please inspect your order upon receipt and contact us immediately if the item is defective, damaged, or if you received the wrong item.
Most items we sell are covered by manufacturers' warranties. If you experience difficulty with a product, please contact the appropriate manufacturer for assistance and troubleshooting help, or email us at sales@theyachtrigger.com. If your order was received via freight truck, you must notify us within 5 days.
Exceptions / Non-Returnable Items Certain types of items cannot be returned, such as custom products and special orders. We also do not accept returns for hazardous materials, flammable liquids, or gases. Unfortunately, we cannot accept returns on sale items or gift cards.
Exchanges The fastest way to ensure you get what you want is to request a return of the item you have. Once the return is accepted, you can make a separate purchase for the new item to ensure it is in stock.
European Union 14-Day Cooling Off Period If the merchandise is being shipped to the European Union, you have the right to cancel or return your order within 14 days, for any reason and without justification. As above, your item must be in the same condition that you received it—unworn or unused, with tags, instruction manuals, warranty cards, and in its original packaging. You’ll also need the receipt or proof of purchase.
Refunds We will notify you once we’ve received and inspected your return and inform you if the refund was approved. When processing a refund, no additional transaction fee is incurred; however, the original credit card transaction fee is not refunded.
If approved, you’ll automatically be refunded to your original payment method within 10 business days. Please allow some time for your bank or credit card company to process and post the refund. If more than 15 business days have passed since we’ve approved your return, please contact us at sales@theyachtrigger.com.

- ARCO Zeus 24V High Amperage Alternators, A4000-24V LTO or A7000-24D: Which One's Right for You?
If Optimal Charging at Fast Idle or at Higher RPMs Is Important to You, this is the Perfect Alternator for You
High Output / High Amperage Alternator: The Highest Power Output in Its Class
Note: If low speed charging is important to you, view our ARCO Zeus A4000-24V Low Turn On (LTO) Alternator here.
24V 7kW Advantage
The ARCO Zeus A7000-24V alternator generates extremely high amperage at cruising and higher RPMs. This alternator continuously generates over 3kW (109 Amps) at just under 3,000 alternator RPM, and almost 6kW (218 Amps) at under 6,000 RPM. To put in real world terms, a marine diesel engine at 1,500 RPM with a 2:1 pulley ratio is generating over 3kW, and a Mercedes Sprinter at 1,800 RPM with a 3.21:1 ratio is generating over 6kW!
Best-in-Class Performance
The ARCO Zeus A7000-24V alternator turns on for cruising or at mid to higher RPMs, runs cooler and provides more power than older designs that are larger and heavier. The newest generation of 24V performance has arrived.
True 24V Alternators
Competitor’s 24V alternators utilize a 12V rotor and field current which is less efficient and limits output at all RPMs. ARCO utilizes a native 24V rotor and field current. This results in our 24V alternator running cooler than competitor’s 24V alternators, having a direct impact on alternator lifespan.
Choose A7000-24V if:
- You primarily charge at cruising rpm or on the road
- You only charge every other day when moving to a new
location - You are willing to trade low RPM output for class-leading output at
mid to high RPMs
*On the power curve graph, select A4000-24V LTO for use cases left of the Decision Point; otherwise, select A7000-24D.
If these do not apply to you, check out the A4000-24V LTO page here.
