I have read it is almond for the color and GE Silicone Caulk II. Many say kitchen/bath version and it is fine but I would think UV rays and temperature changes would be an issue. I had always been told to use the window/door version outside. But I do see the benefits of having it with mold prevention. Do all still agree that kitchen/bath Silicone II Almond is the correct way to go?

This is a really good question and I have to admit, I didn't know the answer. So I went to the GE site and read about all the different silicone caulks. It looks like the two major differences between Silicone I and II window and Silicone I & II bath is that bath has a mildewcide and Window cures faster. For outside work where there might be rain the future, Window is prefer ed.
So for the boat, on things that may get wet and stay wet, I would probably go for the Bath variety. Note that GE states that no silicone caulk is intended for submersion or constant water. There also seems to be a new caulk, GE Silicone II KB supreme which has the features of both, fast cure and mildew resistant. I would probably use that if available.
All that said for deck plate sealing , deck panels etc, some folks use black silicone. You have to apply neatly using masking tape to get nice lines but the up side is that it doesn't show dirt or mildew since it is already black!

Windows and doors are the most important components in ensuring not only structural stability, but also delivering on essential comfort and safety needs. They must be airtight, waterproof, energy-efficient and, when needed in specific environments, soundproof and protect against dust or insects.

Silicone sealant products enable the making of flexible joints that bond construction materials solidly and protect windows, doors and the facades to which they are fastened, to adjust flexibly to fluctuations of size and pressure brought on by changes in temperature, humidity, wind and other environmental conditions.

What are the main long-term advantages of Elkem silicone-based materials for sealing windows and doors?

Silicone sealants are formulated with different functional group structures in the organic silicon polymer main chain to be flexible, adherent and extremely durable over time, so that they continue to deliver the performance level of their initial specifications for many years. The sealing materials applied to window and door systems we produce feature strong tensile strength, good elasticity, and better temperature and ageing resistance than other sealing materials. Silicone window & door sealants work with the full range of structural and decorative building materials used in contemporary architecture or to modernize older buildings, such as steel, PVCs, glass, concrete, etc.
