What are the pitfalls of sailing a dayboat with its centreplate up (i.e. stuck up) . The boat is an 18ft seafarer dayboat, which appears to have a stuck centreplate. The previous owner says it sails fine as has a fair amount of ballast. My understanding was that the centreplate should always be down when sailing and raised for beaching or recovery. I don't want to sail away from the berth if the cetreplate is required, but if the performance and sailing ability is not impacted too much, would like to get some sailing in before end of year. Thoughts? |

| It will go downwind and maybe even (depending on design) crosswind just fine. getting upwind may be another matter. It all depends on what there is underwater without the board. Have you got an outboard to get you back to base? |

Well, the previous owner is partly telling the truth if it also has internal ballast - it's unlikely to capsize on you except in v strong winds. However, if you want to sail to windward, then you are going to struggle. It needs fixing! ------------- Peter Ex Cont 707 Ex Laser 189635 DY 59 |

Is the boat in the water? If not the pics of the hull should give is a few clues? ------------- Spice 346 "Flat Broke" Blaze 671 "supersonic soap dish" |

 Here is a pic of a similar boat, same model. |

| Well, with a stub keel like that it ought to be capable enough crosswind and even make some ground upwind on what would really be a close reach. If I had to get home upwind against the tide in a narrow channel I think I'd need an outboard motor, or else anchor up and wait until the tide changed. |

Right, so it has a small keel as well as a C/B, so yes it should be able to sail reasonably upwind - though it will certainly perform significantly better if you can get the centreboard to work. Do you know what the centreboard is made of? If it's heavy, cast iron, or similar, having it down will also improve the heeling stability, in addition to reducing upwind leeway. ------------- Peter Ex Cont 707 Ex Laser 189635 DY 59 |

Think it is iron or steel, definitely ferrous as appear rusty at top of housing, even with all the grease. |

| Can you get in to swing a hammer ? Presuming it uses a hoist to lift and its own weight to descend, probably corrosion got hold of it |

| Only way to do that would be to have a long drift and use a hammer on that |

| Thanks for the advice, especially comments after seeing the underwater profile of the boat. gives me confidence that should be ok for some sheltered sailing prior to taking her out of the water later and getting the centreplate fully operational |

If it is that corroded I'd certainly wait until she is out of the water in case the pivot bolt breaks when you hit it (unless you are on a drying mooring so you can recover it). When the time comes a bit of percussive engineering should solve the problem as long as he corrosion is not too bad . Rust expands the parent metal (which is why steel reinforced concrete splits when the rebar goes rusty) and if it's too far gone you might have a real mare getting it out. ------------- Spice 346 "Flat Broke" Blaze 671 "supersonic soap dish" |
