Underwater lights on a catamaran

This Lagoon 450F changed owners last month, and quite a lot of improvements and changes were made by its new owners. This project was about adding underwater lights at the back of both hulls.

Everyone has different views on the pro and cons of underwater lights. We can share here a few which comes to our mind.

Pros

  • Looks good: whatever the color, underwater lit boats always stand out while moored or anchored. If you like the attention, that’s one sure way to get it.
  • Docking safety: Mediterranean docking by night (meaning moving backward to the dock) is always a challenge. Lights will improve visibility on other boats, their forward lines etc, and make it easier to measure the distances.
  • Fishing: If you want small bait (shrimps, planktons) to surround your boat, lights are must-haves. They will attract fish. Best color for this will be green or white.
  • Swimming: If you want to go for a night swim, nothing beats the comfort of seing were you’re diving. Aside from safety, it also helps to appreciate underwater scenery.

Cons

  • New holes: This is always an issue, especially for modern boats with already quite a large number of tru-hull. These holes needs to be made with caution, to insure no water will leak inside.
  • Costly: Like most boat equipment, high-quality lights are expensive.
  • Power hungry: Even with the LED technology, these additional lights will take their toll on the boat’s battery bank, especially for those high performing units (6W/12V per unit in our project).

Anyway … this is not our call to make.
Today, we’re here to install 3 lights per hull, B6W model, from the AquaIDEA range:


I guess it doesn’t feel natural at all to drill an additional hole in this hull (which had already quite a lot of tru-hulls of various nature), so we were very cautious here.

The electric connection is made inside the hull, greatly limiting the risk of leak

All in all, we installed three lights per hull.

We plan to put her back in the water by mid-March, and then we will finish some work while docked in Marina Cala del Sole. Obviously we’ll do a real-life water illumination test then, and we will share it with you 🙂
