Internal engine layout

It seems having an internal engine on a Vivacity 20 is very unusual. As such a number of people on the excellent Yahoo forum  have shown an interest in the layout.  I have tried to document in this post.

Engine Housed beneath hatch

Positioned beneath the entry hatch the engine does not intrude into the cabin too much but allows sufficient access for maintenance. This is balanced by lead ballast in bows for balance.

Engine in situ with cover removed

Arrangement of fuel line, exhaust & propeller shaft behind engine under cockpit

Batteries charged by engine

Fuel tank in port cockpit locker

All of this is then counterweighted with a load of old lead piping packed in the bows.

Calculating costs for river boating on the Thames.

This year I am planning to just use the boat for a few overnight trips up the river with the kids. In fact, she may never see salt water again whilst I own her, perhaps not even a tide!

Now having bought her on eBay I am starting to add up the costs of ownership.

Thames River Licence (length x beam x £15.35 psqm): £203.47 (Jan 1st – Dec 31st)

River Safety Certificate: £100 (lasts four years)

Insurance: £106

Mooring on Thames (£1.30 per foot + VAT, per week): £1,622.40 per annum

Total: £2031.87 and rising!

Getting the inboard Stuart Turner engine running again: Awaiting quote.

I have a feeling I will be adding more to this list pretty soon!!

Interview with Des Pollard

Des Pollard’s interview with Tony B for the Twinkeeler Newsletter

Des Pollard was the owner of the former Russell Marine of Southen, Essex, England where most of the Alacrities and Vivacities were built. The info below was taken form an interview with him in the Twinkeeler Newsletter.

Between 1959 and 1980 Des built about 6000 boats. In 1959 he started with dinghies – building Enterprises, Albacores and GP14. In 1960 Peter Stephenson drew the lines for the hull of the twinkeeled Alacrity. The trial model was introduced at 17’3″ and adjusted to 18’6″. The Alacrity started life as a cold-moulded marine plywood craft, the hull being moulded by the same company that produced the DeHavilland Mosquito fighter bomber in WW2.

Within a year GRP hulls were produced. About six months after the production of the Alacrity started an extended version called the Vivacity20 was built, available with either twin or fin keels. A deluxe version was also which had more headroom and a divider which allowed separate cabins and privacy in the heads.

In 1963 the V20 was further extende to produce the V21/650 (6.5m) with it’s slightly odd looking flat level cabin/coachroof or raised deck,depending on your point of view. The V24 came along in 1973/4, designed by Alan Hill, again with twin or fin keel.

Des said “Although it [the V24] sold OK, I favoured the Alacrity, V20 and V21. At about the same time we produced the Islander23, another twin keeler. About 600 Alacrities and Vivacities were shipped to the States. Nine of them are believed to have sailed across the Atlantic Ocean.

V20’s were also built in Jo’burg, Barcelona and Sydney. The V21 and V24 were also built in Spain and the Islander was built in Nagoya which my search indicates is in Japan.

In 1975 Russell Marine linked up with Catalina in the States and produced the 22,25,27 and 30 footer Catalinas which were marketed as Jaguars in Europe, the Middle East and Africa. Des had to fight the Jaguar Car Company in court to use the name, needless to say, he won!
