1. Financing
Does Duffy Offer Financing?
Duffy does not appear to offer direct in-house financing. Financing is handled through third-party marine lenders, either arranged by the dealer or sourced by the buyer independently.
Current Marine Financing Landscape (2025-2026)
| Factor | Details |
|---|
| Average boat loan rate | 7%-10% (avg ~8.88% as of Q3 2025; showing signs of downward movement into 2026) |
| Excellent credit (740+) | ~6.49%-7.9% APR |
| Good credit (670-739) | ~9.78% APR |
| Fair/poor credit (<669) | ~11.6%+ APR |
| Down payment | Typically 10%-20% of purchase price |
| Loan terms | 5-20 years (flexible based on loan amount) |
| Electric boat discounts | Some lenders offer discounts for environmentally friendly electric boats |
Estimated Monthly Payments (Boston Electric Boats Models)
Based on marketplace listings for comparable Duffy boats, estimated monthly payments range from $423-$483/month (varies by term length, rate, and down payment).
Example calculation for a $68,900 Sun Cruiser 22:
- 10% down ($6,890) = $62,010 financed
- At 7.5% APR over 15 years: ~$574/month
- At 7.5% APR over 10 years: ~$736/month
- At 7.5% APR over 20 years: ~$499/month

Key Selling Points for Boston Electric Boats

- Boston Electric Boats could partner with a marine lender to offer streamlined financing at point of sale
2. Docking & Storage in the Boston Area
Where to Keep a Duffy Boat
A 22-foot Duffy needs a slip that can accommodate its dimensions (22' LOA, 9'3" beam) and provide shore power for charging (30 amp service is sufficient).

Important Considerations for Duffy Owners
- Shore power is essential — Duffys charge from standard shore power (30 amp service)
- Charging takes 12 hours for full charge (7 hours to 75%), so overnight docking with power is ideal
- Protected waters preferred — Duffys are rated for winds up to 40 mph in protected waters, but are not open-ocean vessels
- Boston Harbor is ideal — protected, calm, scenic, and the primary territory for Boston Electric Boats rentals/sales
Estimated Annual Docking Cost (22' boat, Boston area)
| Option | Estimated Annual Cost |
|---|
| Summer seasonal slip (downtown Boston) | $3,000-$4,500 |
| Year-round slip | $4,500-$6,500+ |
| Summer slip + winter storage (hauled) | $3,000-$5,000 |
| Summer slip + trailer storage | $3,500-$4,500 |
| Shore power (seasonal) | $500-$800 |
3. Test Drives / Demo Rides
Industry Standard
Duffy dealers typically offer test drives and demo rides for prospective buyers. Authorized dealers are encouraged to let customers experience the boats before purchase.
What Boston Electric Boats Already Offers
Boston Electric Boats operates a rental fleet in Boston Harbor. This is a significant advantage for the sales side:
- "Be Your Own Captain" rentals — customers can experience driving a Duffy firsthand (top speed 6 MPH, "like driving a golf cart")
- Captain-provided charters — customers can ride along and experience the boat without operating it
- Rental as test drive — a rental session effectively serves as an extended test drive; customers who rent and love the experience are natural sales prospects
Recommendations for Boston Electric Boats Sales Strategy
- Frame rentals as "extended test drives" for prospective buyers
- Offer a rental credit toward purchase (e.g., "Your rental fee applies to your purchase price")
- Schedule dedicated demo rides for serious buyers with sales-focused walkthroughs of features
- This is a competitive advantage most boat dealers don't have — customers can try before they buy in a low-pressure setting

Yes. Duffy has an established service ecosystem:

#### Battery Tips
- Avoid 100% discharge — staying above 50% charge significantly extends battery life

- Use surge protectors when plugging into shore power
- Lead-acid batteries have freezing potential in winter — store charged in climate-controlled area
Maintenance Requirements
Duffy boats require significantly less maintenance than gas-powered boats.
The electric motor is the only moving part. The only other operational components needing maintenance are the controller and charger — both are plug-and-play replaceable.
#### Routine Maintenance
- Battery terminals — check and clean regularly
- Battery water levels — monitor and fill (lead-acid only)
- Bottom cleaning — prevent algae/barnacle buildup (can reduce speed by up to 40%)
- Hull care — polish and wax annually (especially dark-colored hulls to prevent fading)
- Bottom paint — reapply annually
#### Annual Service
- Full electrical/mechanical inspection
- Haul-out for bottom paint
- Hull buffing and waxing
- Propeller inspection
- Interior/exterior detailing
#### Winterization (Critical for Boston/New England)
1. Fully charge batteries before storage
2. Disconnect batteries (black cable first)
3. Remove batteries and store in cool, dry location above freezing
4. Connect to trickle charger through winter
5. Drain any plumbing (if applicable — Cuddy Cabin with marine toilet)
6. Clean exterior thoroughly
7. Cover boat securely
8. Indoor/heated storage is ideal; dry stacking also viable
