The FPBs are designed with drying out in mind, and like all aspects of seamanship, we think testing the process in controlled circumstances before we actually need to use it makes sense. The following comments are based on a lifetime of avoiding experience with the subject at hand. But the old saying – it is not if you will run aground but when – is as true today as it was a couple of generations ago when we made our way without long range nav aids and few, if any, charts. <\/p>\n
In the photos that follow you will see FPB 78-1 Cochise<\/em> aground on the Mahurangi river in New Zealand, where she had been parked for a tidal cycle to test the procedures we had in mind for setting kedge and warping off and\/or holding ourselves, so we would not drift into further danger.<\/p>\n We were on a rising cycle of ever higher tides four days before a full moon, so we were reasonably certain that the tidal cycle would help to float us off as the tide came in, as long as we were not drifting further aground with the tidal current or wind.<\/p>\n In this particular case, setting a kedge anchor to hold us in place was required in order to control the boat. Our main anchor is so heavy that it must have a big winch to handle it – at 325 pounds\/180 kg this is not to be toyed with. So we do the following:<\/p>\n To use a bow and stern anchor:<\/p>\n If we find ourselves unintentionally aground, the odds are we need to run the kedge out with the dinghy. In this case hopefully the dinghy will be protected from the sharp edges of the flukes. With a large dinghy and powerful outboard we tow the rode off the reel in reverse, dinghy bow towards the mothership. Our RIB steers better this way and the rode is kept clear of the dinghy running gear. If you are rowing the rode out, or using a small outboard, you may need to flake the rode into the dinghy to avoid the drag of pulling it off of the reel and through the water.<\/p>\n You can see the anchor fluke sticking out of the mud in the foreground and kedge off the stern – the yellow line – off to the right.<\/p>\n The next morning, with the tide filling in, we start the kedge retrieval process. Breaking the Fortress free from a deeply buried position takes a while, and lots of dinghy horsepower. That is a 60HP Yamaha in the photo above. The chain on the end of the rode had been tied short to the bow, so the pull is close to vertical.<\/p>\n In a more protected location, say the side of the Intercoastal Waterway, we will have a lot less scope on the kedge. In this case, rather than retrieve with the dinghy we ease back on the forward chain rode so we can lift onto the stern, using the kedging winch on the aft deck for the hard work.<\/p>\n We should point out that we spent some time this fall parking the boat across from Jarrette Bay where she is now hauled out. The bottom there is much firmer than the Mahurangi River, and as we were hauling out in a few days’ time, we were curious to see if we could do a little damage to the bottom paint.<\/p>\n With the current running at a couple of knots, we set the main anchor at a ten-to-one scope just for room to play with, and then ended up driving the boat hard onto the bank. After a couple of tries we had the technique down where she would stay put. As the tide was falling we were there for six hours until it began to lift us sufficiently that we could drag ourselves off with the big windlass forward.<\/p>\n For lots more on anchors and anchoring, download free copies of Practical Seamanship and Offshore Cruising Encyclopedia here.<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"\n

\nLinda is wearing a headset (AKA the Wankaphone) so we can communicate easily at a distance. The folded arms and countenance indicate her opinion of this particular test. It is something I have seen before when your correspondent ignored her suggestion not to>>>fill in the blank <<<< and we ended up running out a kedge in earnest.<\/p>\n![\"\"](\"https:\/\/setsail.com\/wp-content\/uploads\/2017\/12\/Cochise-Mashurangi-R-dry-out-103-of-7-1024x683.jpg\")
\nWe are in soft mud here, and looking down about 14 feet aft of the bow.<\/p>\n![\"\"](\"https:\/\/setsail.com\/wp-content\/uploads\/2017\/12\/Cochise-Mashurangi-R-dry-out-102-of-7-1024x576.jpg\")
\nThe prop, prop skeg, and rudder are deeply buried. We are not going anywhere for a while!<\/p>\n![\"\"](\"https:\/\/setsail.com\/wp-content\/uploads\/2017\/12\/Cochise-Mashurangi-R-dry-out-105-of-7-1024x576.jpg\")

\nThe hardest part of this process is actually bringing the anchor into the dinghy. We have since made a bib to tie over the bow which protects the RIB tubes from the anchor.<\/p>\n
