Pic - Shaver rope cutter fitted

[Tintin]

I thought some may find this pic useful of the shaver type rope cutter, recently fitted to my new boat.

While the unit cost was lower than other rope cutters the engineering cost from the yard was the same again, due mainly to the need to modify the P-bracket and add a bush onto the shaft.

No doubt as these become more popular and yards get used to them the fitting cost will drop.

Only time will tell if it is more or less effective than the other types.

Where I had my problem with a Stripper was the thread pitch of the three bolts holding the static part onto the P-bracket. The thickness of the metal here is so little that there was only about one turn of thread per bolt holding it on. It would have been better to drill and tap right through the cutless bearing but this did not seem an attractive option at the time. On two occasions when I picked up ropes in the water the threads stripped out of the P-bracket.

The thread is finer so time will tell

Vyv- I had a similar problem when a Dawin Candidate at a Gosport yard drilled, tapped and fitted the fixed part of the Stripper to a composite P bracket. It ripped right out first time it caught a rope.

Stripper do a special fitment for composite brackets. Due to the time frame I made one from a heavy S/S tube and strip.

It has the fixed part welded to it and slips over the bottom of the cutlass and has two legs that bolt to the sides.

It is still going several years later and has been used in anger more than once.

It is a good remedy for a thin wall P bracket.

Thanks Comrade,

The other big difference is there are no shock loads when rope is cut, just forward pressure on blade.

I believe that Ambassador offer a similar fitting now for metal P-brackets.
