Harbor Tender Idea
 

I'm working on an idea for a tender to get back and forth to our sailboat in
a cove with no docks or other facilities. If this is something that might

Lots of sand. I would just use standard trailer components. The sand
problem won't be any worse than it would be for a boat trailer. More hours
of immersion while the boat sits on a mooring will probably shorten the life
of the underwater stuff so I will put zinc's on everything and just plan on
replacing things every few years.

What are you going to use for wheel bearings, and how are you going to
keep the sand out of them, assuming there is sand...

Why not just use beachcat wheels?

Are they street legal? If so, do you have a link?

Aside from your design ideas, you do realize that you're proposing a 16'
tender for a 32' boat....

This tender is never intended to leave the harbor. We would have another
dinghy to take with us.

What about a catamaran type dinghy? It could dismantle into three or four
pieces light enough to carry in a mini-van/station wagon but be stable
enough to stand
up on.

Here in WA you would have to register the tender both as a motor boat and a
trailer. Never heard of it being done, but I'm sure the state would love to
work with you on it.

Just use spring loaded automatic trailer bearing hubs. You over
pressurize the axle with grease (the spring compresses) and this keeps
the entire journal filled with grease .... and excludes water, etc.
You must let the bearings & journals 'cool-down' before you enter the
water (the sudden cooling with water will cause an internal vacuum
which will suck in water).

I dunno about that. I've been trailering boats for a number of years,
but I've always used decent ramps and never buried the axles in sand or
mud. Sure, there is some sand "in suspension" floating around, but if
you are launching by rolling down a beach in loose sand, it is going to
get into your bearings.

I doubt you'll get a season out of metal axles and bearings.

There are some launchers around for PWCs that use large nylon or plastic
wheels and corrosion-proof axles. I don't know the particulars, but you
might want to inquire about these...

Good luck. Me, I'd grin and bear it with a decent inflatable and a pair
of tall fishermen's boots.

I expect it will be the same here and the boat will have to have brake
lights and a license plate.

Interesting idea but in the end I think you'll be happier with a hard
bottom inflatable (perhaps with beach wheels), and a lightweight
trailer.

Many years ago I was working at boat yard in Marina Del Rey, near Los
Angeles, Ca, and saw this concept.

Some guy bolted a trailer to the bottom of an old wood boat. 14 foot,
maybe. 20 horse outboard.

I only saw it once, but it stays in my memory.

I can see it now, heck of a wake with the trailer hitch sticking out of
the water in front of the bow when on a "plane". A do it yourself
tsunami maker.

You see the darnedest things at public launch ramps.

Since the distance is short, this boat would only be used at low speeds.
The big reason for it is that the beach is so flat that there will be 10 -
20 feet of water between the water's edge and the trailer when it is deep
enough for a trailer boat to float on or off. That makes launching and
recovery a real pain in cold Maine water. Also, getting a boat on and off
when there is a small surf running is difficult.

If the distance TO the beach is short then plain journal bearings
(journal AND thrust) would be appropriate. Polyurethane or Acetal
co-polymer plain bearings would be suitable also for small road travel
distances. You design them for an 'intereference fit' into the journal
- with an 'assembled' clearance to the shafting of 1- 2/1000's of an
inch clearance per inch of shaft diameter. Availability is from
national bearing 'distributors' such as Bearings Inc., etc.

I believe the Brits have a boat beach dolly that fits right into a road
trailer for applications like yours. That way the road trailer avoids the
salt water and the dolly/boat is light enough to wrangle by hand. Get the
fat dolly tires for soft sand.
