Boat Hull Calculator Area Calculator for Paints

How much Antifoul or Topcoat do I need? That's a question we often get asked. 

Coverages of marine paints vary and so does the surface area from boat to boat so we have put together a couple of calculators which will tell you how many tins you will need to purchase of the specific paint you are looking at. 

For it to work well you need to know certain dimensions of your boat, such as the length of the waterline, beam, draft and others for above the waterline surface. (This is explained on the calculator don't worry.)

How to Use

First, we need to calculate the surface area we need to paint, to do this, select

Sizing Cable & Cable Size Calculator

Getting the right size cable, whether it be for running lights, chargers or larger devices like inverters, inverter chargers or fridges is important both in terms of ensuring it can safely carry the current but even if you know the correct cable for the amps an overlooked factor is the voltage drop across the distance. Both of these factors are important for a proper installation. 

For example, for a 30A 12V battery charger you could use Oceanflex 4mm2 cable as that is rated to 39A but if you were running the cables 2.5m you would lose around 0.71v due to voltage drop meaning your charger won't charge as well affecting it's performance.

We have put together a handy cable sizing calculator to ensure you are getting the right cable for your installation, whatever it is. 

Simply enter the Voltage,

CORRECTLY SIZING YOUR BATTERY CHARGER

When it comes to charging your batteries, it is crucial to have the right battery charger with the appropriate specifications. An undersized charger will take too long to charge while an oversized charger will charge your batteries too quickly and shorten their lifespan. Therefore, it is essential to know how to correctly size a battery for your batteries to ensure longevity of your batteries.

In this article, we will explain the concepts and we have a handy calculator below to save you from doing the calculations.

HOW MUCH ANCHOR CHAIN SHOULD
YOU LET OUT WHEN ANCHORING?

Anchoring is an essential part of boating, it opens a whole other world of opportunities. You are not tied down to making it to a marina or mooring, if you find a nice spot you can stop for a meal or have a lover overnight stay. Being able to set an anchor properly is critical to keeping your boat in place and one of the key components of anchoring is determining the correct length of chain to use. In this article, we will explore how to determine the appropriate length of chain for your boat.

The Importance of Chain Length

Before we dive into the specifics of how much chain you need, let's take a moment to understand why chain length is essential. When you drop your anchor, the weight of the chain helps to keep the anchor on the seabed, preventing

Setting Up An Inverter Guide

Installing an inverter on your boat or van is great, it allows you to run certain appliances such as water heaters, toasters, fridges and other household appliances while you’re not hooked up to shore power. This brings more freedom to your adventures as you are not missing out on toast, hot water or logging onto your work laptop when stopping at that pretty anchorage or pitch without outlets.

If you are fairly competent with electrics fitting an inverter is actually simpler than you may think, you just need to make sure to install certain components to keep everything safe. This is a guide for someone who is looking to fit it themselves, we will explain everything you need, and go over the steps when fitting an inverter for someone who is knowledgeable working with electrics but maybe doesn’t know the process of fitting an inverter.

Fitting an Inverter Charger Guide

Inverter chargers are great, they combine the power of a battery charger and an inverter into one unit. On installations such as boats or vans this can save valuable space but they offer a few other benefits above having the charger and inverter separate as well.

• Less cabling – Inverter chargers use the same cabling from your batteries for both the inverting and charging side so there is less cabling running to your batteries keeping the installation cleaner and reducing costs on cables.

• Better for your batteries – Inverter chargers use the same cabling for both inverting and charging so when you are hooked up to mains power, your AC loads will run directly from the grid instead of from your batteries which allows them to charge your batteries. This results in a faster
