Re: Silicone BT seals

Germain Jean-Pierre

Hello William,

I flew heavies and they all use a flow form of checklist.  I have never needed a written one but you could develop your own, specific to your vessel, broken down by areas of concern.  

Include BT pin removal before leaving the dock.  Start the engine 10 minutes before leaving the dock if it is likely you’ll need to give it the beans… perhaps run the genset if you expect to use the BT or windlass.

Fair winds,

Was a private pilot and very familiar with check lists. But…in my sailing I never crossed the concept of checklist from flying pre-flight over to leaving the dock. Humbling realization. Anybody have a checklist for going bow to stern and back again that they could share?

Absolutely agree on releasing the pin at the dock or anchorage and decompressing the seals.  On our boat, pulling the pin and flipping the down switch for as short a time as possible usually lowers it just enough to take the pressure off the seals. This leaves the pressure on the cable and the lowering motor mechanism but there is little force if the anchorage/dock is quiet.  I do the same on the hard except i don't like to leave it on the lifting cable/motor mechanism for such a long period of time.  In that case I use a split pin and rest it on that rather than the locking pin.  Because the split pin (AKA cotter key) is a smaller diameter you can rest it on the thinner spllit pin and the seals are not compressed as much.  This may not seem to be a significant distance but it really reduces the compression.  I think it is that tight, tight compression that gives a good seal--but, again--leaving it that way for a long time causes a problem.  Doing this seems to dramatically reduce the leak problem.

Regarding check lists, let me add that they way we prepare for departure is to start inside and go from bow to stern, then outside from bow to stern checking as we go.  So our first item is the bow thruster, windlass/genoa breaker, inside windlass switch, front hatch, cabinet latches, head hatch, toilet emptied, front bilge check......etc...etc.....ending with a look at the rudder quadrant and rear hatch.  We then do the exterior--bow to stern--starting with running lights, anchor, windlass....etc....ending with davits and stern light.  We do the engine room last.  For us, it is the easiest way to do a thorough check.
