My slip fees are now paid and my appointment is set to have a bilge pump installed in my 1975 Mako 191. Now I need to know what other items I really need to buy?

Ropes and Fenders I guess are it?

Help with what else I need

A backup bilge pump, a tight fitting boat cover that will not blow off in a storm, fenders of course, some good dockline or rope, strong cleats..

Possibly a shore power line to charge your battery if you are planning on leaving the boat for a long time.

All that comes to mind at the moment.

the bilge pump you need is one with an automatic level.
that way the pump comes on when the water is at a certain level...

i would also suggest a solar powered battery charger.......and if you only have one battery......get another with a battery switch....

oh yeah........buy insurance !

Re: What items do I need to sucessfully keep my boat in an open slip?

Hi, Bugs- I stay wet all season, too. What kind of 'slip'?

Will you be tied broadside to a finger pier? Or, will you back in with the stern to a dock and the bow situated between 2 pilings? Or, will you tie broadside to a dock? If the last, is the face of the dock 'flat' to your boat, or are there pilings set between the dock and your boat (navy pier)?

I'm just curious. In a couple of these cases (backed in between pilings, or broadside to a navy pier), fenders are secondary. Your mooring lines do the work. I tie brodside to a navy pier, and need to use mooring whips to hold the boat off the dock. It's a pain, but I get it cheap :)

Is there tide action? Are your zincs up to snuff?

If you can cover it, that is the first thing to buy... a cover. Sinkings occur most often while the boat is tied up at the dock. Rain tries to overwhelm the pumps, which might be robust enough, but they usually put a smack down on the batteries.

If the boat is self-bailing, a cover is less of a concern.

By the way.... a bilge pump is a MUST... whether your wet slip or trailer the boat and dunk it. Once you take on water, and it's sittin' in yer bilge... ya need a pump! It might self bail, but boy oh boy... ya don't leave port w/out a bilge pump.

Where is the boat going to be and what type of water??

Re: What items do I need to sucessfully keep my boat in an open slip?

I'm with JoLin--we need a lot more info. Tides, wave action, pier type? Boat type? How well supervised is the pier and how far away are you?
Forget the solar and the trickle charger, if you have a good battery. Just check it every week or so--and run it.
Forget the fenders; tie the boat off the pier (unless it's a floater with zero wave action).
Talk to the dockmaster and others nearby on how to tie up. With tides it can be tricky, and fatal (to your boat).
As for covers, depends on the boat, and your climate. Covers on the whole boat can be a pain on a wet slip. Unless you have the kind of boat that's not made to be left outdoors, you might not need to cover much. For example if it's a center console, get a cover for the console and remove the cushions. Look around your marina and see what others are doing. Also depends on how much you use it--cover it if you are leaving it a long time. Where I am, few people cover the whole boat, and those who do have sofa boats that don't weather well.
Also, would you pull it out if a big storm system was headed your way, or leave it in? Do you get those afternoon squalls?
How about security--can you leave stuff on board? some stuff? Do you need to lock anything?
I like a battery switch that cuts off everything except the bilge pump. It saves on corrosion and drain from the inevitable small shorts, prevents a big short/fire (BTDT).
Hide a key on the boat, so it will be there (a) when you leave yours at home and (b) you need the dockmaster or neighbor to help out in an emergency. In fact, see if you can get a storm buddy system with someone else there that you know or feel like you can trust. Boaters have to look out for each other.

The slip has water and electric. Very calm water.

That's a picture of where my slip is.

I have a Mako 191 the deck is self bailing. But I am in the process of adding a bilge pump an onboard charger.

Re: What items do I need to sucessfully keep my boat in an open slip?

Good- take a close, close look at how other boats are tied up there. Your bow lines, stern lines and midships spring lines are what hold you in place. Fenders won't do anything for you. If it's salt, tide swings will also factor into how much slack you leave in your mooring lines, and where you position them on the pilings.

(very) basically- you'll have a line back from each stern cleat to the dock cleat. If you have tide action, you'll want to criss-cross them. Port boat cleat to starboard dock cleat, and vise versa. That makes the line longer, increasing the up-down swing radius (it's a good thing :) )

At the bow you run a line from bow cleat to piling, holding the boat suspended between them so the bow can move up-down and wander between them, but can't touch either one.

Spring lines from the boat's 'mid' cleats to the pilings at the bow keep the boat from moving too far aft and bouncing your stern off the dock.

Takes a bit of work to set things up, but you really only need to do it once. Add lines when a storm's coming.

Good luck- hope you have a great season!

fenders sure help when the boat next to you isn't tied as well as yours.

i leave permanent spring lines tied from the pilings to the dock with loops tied in the middle for my mid ship cleats. makes things easier for me, especially when im out alone.

Re: What items do I need to sucessfully keep my boat in an open slip?

with a self-bailing deck you don't need a cover or a charger; you won't get that much water in the bilge in the first place. If you do, look at sealing your deck-plates and other areas where water drips in.
BTW I have a 17' open boat that drains into the bilge (no scuppers) and a single battery/float switch has worked for 20 years. Occasionally we noticed the pump had failed after a big rain and pumped it out before any problems.*
But you do need a bilge pump and a float switch, hooked up independently to the battery, fused. That's all.
To me, a charger is an unnecessary expense and something else to go wrong, as well as constant power that is bound to "leak" and exacerbate electrolysis. KISS

*like once, the shaft on the pump's impeller broke. Nothing you can do about the stuff like that which inevitably happens to the best of systems. Just check on the boat regularly and try to get some sleep when you can't!

This is why you should have a backup pump. The ideal system is two automatic pumps, one at the lowest point in the bilge and one slightly higher up.

This way if the bottom pump fails then the second pump can take over if needed. Also if you get into a stituation were a single pump can't handle the water load then the second can be a lifesaver.

Bilge pumps fail, frequently. The more rain you get in your area the harder it has to work and the sooner it will fail.

Hi, Scutly-

Where do you slip your boat? I tie up at a private dock in Oronoc Creek. That's 1/2 mile east of the Bayshore marina

Re: What items do I need to sucessfully keep my boat in an open slip?

trendsetter, you are right, for a larger boat. This is a 17' DC with no room for two pumps; kept at the house in the water under daily supervision. I carry a hand pump as a back-up. It has positive floatation so it can hold a lot of water and remain level and not flood. Also, being smaller, this boat doesn't go out in the rough waters--although it has.
As we speak I'm in the process of installing a second pump in a larger boat.

Ladies and gentlemen, self-bailing decks are wonderful.

That being said: Get a bilge pump.

I have strolled past upside down boats that were in their dock, which had sunk, because their self-bailing decks didn't bail all the water. The boat listed in a corner, water poured over and FLIP... the boat is upside down in a mooring slip.

It is to the point that I walk casually past these boats... mostly center consoles.

They don't need bilge pumps! Didn't ya know? If I hear one more insurance guy or surveyor yap on and ON and ON for hours about scuppers and self-bailing and design flaws at the scene of the flipping... well... I am gonna flip. These guys show up with clip boards and LOVE to hear themselves talk. I swear, they live to yap about scuppers. It's like sex to them. They secretly love failed scuppers and other design flaws so we can here 'em yap on about scuppers, deck heights and other stuff you never want to hear.

My knucklehead friend lost two boats the same exact way: Flipped, in docked, cause they took on water.

Hey, they had self bailing decks, so it MUST have been my imagination.

BILGE PUMP!

Re: What items do I need to sucessfully keep my boat in an open slip?

I moored my '22 starting last year and i've learned a lot, definately 2 auto bilge pumps- the bigger the better, a reliable way to maintain the batteries, this will keep your pumps going longer should you spring a leak or it rains heavy for a long time, plus dead batteries on the water are a big PITA. If your in salt water bottem paint is probably in order, I didnt do mine last year and keeping the growth at bay was almost impoosible, needless to say mine is now painted. A boat cover is nice but i opted to make my boat more water and sun resistant- no more nonremovable cuishons and no more carpet. Make some friends at the marina- if your boat has a problem it would be nice know about it.

I'm also big on covering the boat. I have a fitted cockpit cover that's always on when I'm not on the boat. It keeps 99% of rainwater out of the bilge and protects everything else from UV damage.

Galvanic isolators

If you connect to shore power in a marina you should invest in a galvanic isolator.As soon as you plug in you connect yourself to your neighbouring boats through the ground wire in your shore power cord.This creates a galvanic circuit between you and the other boats(not good if your neighbours have bad stray electrical currents on their boats,it will eat up your anodes fast)

The galvanic isolator interrupts low galvanic voltage/current but will connect larger amounts in the case or an appliance short that needs to be grounded.

An Isolating transformer will perform similar function.*
