In reply to Removed UserBlaseSlayer:
I'd say you would be best off with a layering set, good base layer made from merino or merino-polyester, good fleece, good synthetic puffy and a good rain jacket. This prevents overheating as you can mix and match depending on circumstances and activity.
The rain jacket is going to be a challenge. Saltwater tends to eat technical gear for breakfast so I would have a look at the sailing jacket market, as those tend to be a bit more built for that particular use case than technical outdoor sports wear.
The tricky thing with anything garment and technical is that the more you are willing to spend on it, the better it will be able to dump your heat. Cheap membranes generally have a poor moisture vapour permeability rating (and also don't last as long generally speaking, buy once cry once).
