Marine electronics in Cold Spring Harbor and Lloyd Harbor.
Cold Spring Harbor is narrow, deep and quiet, with a great deal of private dockage tucked along Lloyd Harbor and Lloyd Neck. Many of the best boats on this stretch of the North Shore never sit in a public marina at all.
We work at private docks and moorings here as readily as at a marina — navigation, radar, networks and helm work, done at the boat by the person you spoke to on the phone.
About Cold Spring Harbor
A harbour where most of the boats are at private docks.
Cold Spring Harbor and Lloyd Harbor are not marina country in the way Port Washington is. The waterfront is largely private, the docks belong to houses, and a lot of very good boats sit at the bottom of somebody's lawn.
That suits how we work. We come to the boat, so it makes no difference to us whether it is in a slip at a marina or on a private dock down a driveway. It does mean access is worth sorting out when you book — gate codes, where to park, and whether anyone needs to be there.
Private Dock Work
How a job at your own dock runs.
Access first
Tell us how to get in when you book — gate code, driveway, whether the dock is walkable with tools. It saves the first twenty minutes of the visit.
Power at the dock
Most private docks have shore power, which makes the work straightforward. If yours does not, say so and we will bring what we need.
You do not have to be there
Plenty of jobs are done with the owner at work. As long as we have access and know what you want, we get on with it.
Local Water
Cold Spring Harbor and out to the Sound.
Deep and narrow
The harbour itself is easy water. It is the run out past Lloyd Point onto the Sound that argues for radar and AIS.
Lloyd Harbor moorings
A lot of boats here live on moorings through the season. We work them the same way, planned around the launch.
Short season, hard use
Boats here tend to be used intensively for a few months, which is exactly when a failure is most annoying. Off-season work avoids that.

What Comes Up Here
The usual jobs.
Chartplotter and radar packages
The standard North Shore pairing, for the fog and the Sound traffic.
Starlink and onboard WiFi
Very common on the cruising boats here, mounted and powered off the house bank.
Electronics repair
A lot of what we do at private docks is fixing what is already there rather than replacing it. Often it is a connector or a power fault, not the display.
Bigger Boats
Working on something larger?
A lot of the work in Cold Spring Harbor is on yachts — networked helms, multi-display refits and
integration on boats forty feet and up. There is a page for exactly that.
What It Costs
Time and materials, told up front.
$280 for the first hour with one installer — that covers travel up to
30 minutes each way and setup — then $140/hr billed in 15-minute
steps. A two-man crew is $440 for the first hour, then $220/hr. Cold Spring Harbor is at or near the edge of the included 30-minute travel window; if a specific address falls outside it we tell you the travel figure before booking.
There is no four-hour minimum and no separate setup charge. Parts are at cost plus markup, and we
supply what we install so the warranty sits in one place. We do not give fixed quotes — on a boat
with systems already aboard a firm number gets padded to be safe, which is not fair to you.
Sixty days on our labor; equipment carries the manufacturer's warranty.

I had my marine electronics installed by Dave and did a great job. I especially appreciated that the final price matched the estimate, no hidden costs.

Dave and his team are professional, responsive and transparent. Couldn't ask for anything more. Working with them was great; the attention to detail and willingness to communicate and problem solve meant our project got done on time despite the short notice.

Great install by David and his team! Complete electronics update, with new panels, gauges & switches. David is very meticulous, detail oriented in his planning and installation.
Questions
Cold Spring Harbor questions, answered.
Will you work at a private dock?Yes — most of our work in Cold Spring Harbor and Lloyd Harbor is at private docks. Give us access details when you book and it goes smoothly.
Yes — most of our work in Cold Spring Harbor and Lloyd Harbor is at private docks. Give us access details when you book and it goes smoothly.
Do I need to be there while you work?
Not usually. As long as we have access to the boat and we are clear on what you want done, plenty of jobs are finished with the owner at work.
Is there a travel charge out here?
Generally no — Cold Spring Harbor is within or close to the 30 minutes each way included in the first-hour rate. If a specific address falls outside it we tell you before booking.
Can you work on a boat on a mooring in Lloyd Harbor?
Yes. Let us know when booking so we can plan around getting out to it and bring everything needed in one trip.
My display works intermittently — is it dead?
Often not. Intermittent faults on boats are usually power or a corroded connector rather than the unit itself. We diagnose before recommending a replacement.
When should I book winter work?
Early. The off-season fills up with refits, and the boats booked first are the ones finished before the water warms up.

Book It
Tell us about the boat.
Send the make, model and a photo of the helm. That is usually enough to get the job done in one trip.
