Fastening your self made construction with cable ties seems undeserved luxury. Every item could and should be fastened with special design shiny fastening bracket. Unfortunately there are some arguments for cable tie.

This year I had a trip with Amphibear in Baltic Sea also. As result in some places there is visible galvanic corrosion. Amphibear has frame from AISI316 steel for Mercruiser stern drives. And no matter of zinc anodes on stern drive there are visible marks of white oxide between frame and leg and on small aluminium alloy oil reserve.

Changing beam lights, moving VHF antenna location and a lot of other modifications result sometimes empty holes in your cabin. Amphibear had three visible not covered and not needed holes, some from modification of modifications, one accidental.
