boom not horizontal


 

?

?

?

I have a 2014 Hartley Wanderer ( sail no 1741) and am trying to resolve an irritation in that my boom is not level but dipping towards the aft of the boat.?

?

We have placed the rear of the mast foot at the end of the mast step, up against a fitted nut and bolt.? (Though I note there is another hole which is available.)? The tabernacle pin is removed.?

?

We have replaced the ¡®standard¡¯ stay adjusters (Allen A4372, see ) with vernier adjusters (Allen A4272) and pressed rigging links (Allen A4138) so as to give a longer adjustment range.? We have not measured the length of the shrouds.?

?

The Selden mast spreaders are 430mm long but the spreader deflection is 195mm rather than the 165mm specified by Selden for a Wanderer¡¯s set up or 178mm suggested in WCOA technical data at .? (As an aside, the Selden Wanderer¡¯s data sheet does not seem to be available anymore.)? We did not measure the mast prebend.

?

Our mast was rigged with the jib reefing line below the main sail reefing line.? We found that this did not give us enough room to achieve a reasonable tension in the shrouds so we reversed them.? The Cunningham is not fitted.

?

So having tensioned up the shrouds to 280 lbs via the jib (checked with a borrowed Loos PT-1M), the mast rake is 22 feet and 6 inches (the closest we have managed to get it).? But the boom is nowhere near horizontal and the kicker seems to make little impact on the boom¡¯s levelness.

?

So two questions.?

?

Does the spreader deflection make a difference?? Given it is slightly larger than specified, which in turn means the main sail hits the end of the spreader sooner (at a smaller angle), thus limiting the broad reach set up without the impacting on the shape of the sail.

?

What else can one do to adjust the level of the boom????
thank you

Are you getting the main up to the top of the mast? ?Don¡¯t put the boom on the gooseneck until after raising the sail. On my boat the luff has shrunk so it¡¯s quite hard to pull down.?

Hi Eleanor

I too have a Hartley Wanderer and mine also is lower at the aft end. I¡¯ve noticed this on older boats too so am thinking it is probably normal.?

Thanks for the suggestion Mike. I will check the height of the top of the sail when we rig the boat on Wednesday. I have to confess that we have been raising the mainsail with the boom on the gooseneck, so maybe our technique has not helped.

Hello John
Thank you for the reply. The dip in the boom was fairly pronounced until we altered the shrouds. It was catching my head regularly when tacking, so I think it was a bit lower than it should have been. Sadly we don't have any other wanderers at our club so have none to compare ours to.

We have had a similar problem on our sailing club Hartleys. Part of the problem can be that the mast step can slide forward. We have found that it helps to put another bolt in the mast step, in front of the mast, then put a wooden or plastic block in the mast step channel, between the bolt and front of the mast step, to push the step right back against the aft bolt (you can¡¯t get a bolt directly in front of the mast due to sides of the tabernacle obstructing the holes). You can then remove the tabernacle pivot bolt, without risk of the mast step sliding forward, and pull the mast more upright. We have found, however, that the shrouds are very short and that they can only be put in the top holes of the chain plates.

As mentioned previously, it is also important to make sure that the mainsail is pulled as high as possible. This is best done before putting the boom on the gooseneck.

If all fails, you can take up some tension on the reefing line to keep the boom from drooping. We sometimes do this with novice crews to increase the head clearance, although it does upset the sail shape.

Hope this helps.

Regards

Mike

On the Hartley boats I thought the slot in the foot of the mast was supposed to sit over the bolt in the track so it can¡¯t move either way.

This means removing the pin and lifting the mast after getting it upright.

Hi Mike,

That's very interesting. I hadn't heard that suggestion before. I'll give it a try.

Mike
