Our History

Some Significant Milestones in Our History

1961 - Seamark Nunn was first established in 1961 by the husband & wife team of Mike & Rosemary Nunn, making us one of the longest established family-run boating businesses in the UK. The company emerged as a boat building and chandlery business to support the growing boating community on the Suffolk & Essex Coast. From its inception, the company built up a solid reputation for building fast racing dinghies in wood and later GRP, and during the 1960s and 1970s was a favourite builder for the OK Dinghy, National Solo and International Optimist, of which many of the latter were exported into Europe.

1980 – We began our involvement with the sales and servicing of outboard engines, initially becoming dealers for Seagull and Evinrude outboards. The Mariner outboards dealership was added in 1988 followed by Suzuki Marine in 1990 and Honda Marine in 1993. Our outboard engine workshop can deal with engines from 2HP-350HP, worked on by our manufacturer-trained technicians. We are now one of the largest outboard engine centres in East Anglia and can offer servicing and repairs both on-site and off-site where required.
1999 - saw the launch of our first ever e-commerce website, making us one of the first UK chandleries to start retailing marine products online. Our website now delivers a significant proportion of our total business and we pride ourselves in keeping our prices as competitive as you will find anywhere on the web.
2006 - after a 6 month building project and significant investment, we opened our newly expanded chandlery, more than doubling the size of our retail and office space.

Marine Retailer of the Year Award

2012 - Seamark Nunn were announced as Marine Retailer of the Year 2012 at the Marine Trade Association / Boating Business (MTA/BB) annual industry awards dinner held during the London International Boat Show, confirming our position as one of the leading marine equipment suppliers in the UK.

Our choice of outboard engine products was complemented by the introduction of the Torqeedo range of electric powered motors - we are now the largest Torqeedo dealer in the UK by units sold.

In 2014 the Yamaha outboards dealership was added to our portfolio of premium marine products, reinforcing our status as the #1 outboard engine dealer in East Anglia.

Fake and Fraudulent Voucher Codes

It has been brought to our attention that there are numerous different websites offering discount vouchers for our store. We are aware that these are easy to find by searching for Seamark Nunn discount codes and as a result a number of our customers are being misled into entering details to claim a voucher code, or being directed via these websites to our website with the claim of a percentage off products.

We want to be really clear that these websites are in no way affiliated with us and therefore are using the Seamark Nunn brand without permission. We do not use third party websites to offer discounts or price promotions and these advertised discount codes will not work. You will therefore always find the best price by going directly to the Seamark Nunn website and any voucher or money off promotion we run will be advertised from our official channels.

You will only find official voucher codes in the following places:

Our website
Our email communications
Our social media channels

Fraudulent voucher code websites mislead you into entering personal data by promising discounts that are not valid. The sources behind these fraudulent sites can use your information and combine this with other sources to provide a clear picture of your identity in order to conduct identity theft or other types of fraud. We strongly advise that if you are a UK customer and you have been a victim of fraud that you report the incident to
