SR4 Manual and Davit Points

Hi,

I'm trying to find out how my searider 4m can be fitted with davit points. There's a plate on the transom providing warnings for davits - so it should be possible. It has a number of tapped bolt pints in the floor and molded transom supports (most of which are plugged at the moment) which look promising.

Does anyone know where I can find the right manual?

With thanks in advance...

Hi, I know these ribs inside out...

There are two types of decks and neither are necessarily made for load lifting...

The best thing to do is give me ca call on 07778 555884 it all depend on the model and how you are going to use it

That'll be a heavy beast to lift if the hull is flooded too...

If you've got moulded knees you have a "Deluxe". The tapped holes in the floor will be for seating.

The hull will drain quicker than you can lift the boat on davits.

We've lifted ours (rescue spec) using a single point secured to a ring bolted to the inside of the bow ring and to two eyebolts at the top of the transom struts.
Not really suited to davits though.

I think there's a searider on davits here in the marina. I'll pop over tomorrow and have a look.

SR4 Manual and Davit Points

If it's the deluxe (moulded transom knees) there will be 4 lifting points, 2 on the moulded knees and 2 near the bow on either side of the deck where it's moulded up at about 35deg.

All of the plugged holes on the deck are for seating.

Thank you for the help. It looks like it's the 'deluxe' - i've found the 4 points described. Great to find that Avon installed them by default.

The two in the bow are under the dashboard, however it looks like if i rig it with a bridle to a single point, the lines can run neatly over the seats and under the dash.

Many thanks - immediate question answered. If anyone has a manual for the SR4 Deluxe that would be great...

Assuming all of the floor boarded area floods to a depth of at least 2 inches. Thats 2.5msq So to lift it just 2 inches might be an extra 125kg compared to lifting the boat alone. You have to lift it to drain it.

The drain hole is about 10cm diameter and based on some fairly basic calcualtions here Flowrate Calculation for a Draining Tank is probably draining at 8litres a second. So to drain that 125litres will take 15seconds. I'd have expected to be winching faster than 8 inches every minute or it'll be a long slow winch - Not sure how high you are winching but 1m seems likely. At that rate of winching thats 5 minutes of continuous winching to lift 1m. So I suspect you will for a reasonable period of time have the boat with water in the hull pulling against the lifting davits. Also don't know what volume is in the tank...

The ballast chamber isn't fully flooded unless there are people in the boat...
