The Blue Seas cable clam is the way to go. After trying many different
things over the past 40+ years, these were the only thing that were truly
watertight and you can have a continuous cable if that is a goal. Myself,
since I take the mast down every year, need to have a connection in the
cables below deck. I have a terminal block inside the head locker for the
12v power cable (completely dry and out of the way) and I use a Shakespeare
PL258 splice connector for my RG8X VHF cable (also in the head locker).
