TECH­NI­CAL

Canal Boat - - The Boat Test -

Grape Es­cape is pow­ered by a Beta 43 en­gine. There’s also a Ve­tus 95kgf bow thruster.

For elec­tri­cal power there’s a size­able bank of seven 110Ah bat­ter­ies for the do­mes­tic sup­ply; it’s a typ­i­cal Bourne spec­i­fi­ca­tion and means there’s plenty of scope for moor­ing up for a day with­out hav­ing to run the en­gine.

That’s par­tic­u­larly true on this boat, which has a 250W Pana­sonic so­lar panel on the roof to top up the bat­ter­ies via an Epever MPPT con­troller.

For heat­ing there’s a We­basto diesel boiler to com­ple­ment the Re­flex stove.

In ad­di­tion, there’s a heat ex­changer on the en­gine, so the ra­di­a­tors can be

warmed up while on the move. It’s a good way of mak­ing use of ex­cess heat from the en­gine.

Bourne have fit­ted them to quite a few of their builds but it’s al­ways been a sur­prise that more boats don’t have one – par­tic­u­larly for fans of boat­ing in colder weather.
